Answer:

Step-by-step explanation:

Original problem:

2x + 7 > x + 19

Subtract x from both sides.

x + 7 > 19

Subtract 7 from both sides.

x > 12

Problem with 3 instead of 2.

3x + 7 > x + 19

Subtract x from both sides.

2x + 7 > 19

Subtract 7 from both sides.

2x > 12

Divide both sides by 2.

x > 6

2nd question (I'm not sure I understand it correctly.)

x < 3

Solving 2x + 7 > x + 19

2x + 7 > x + 19

Move 7 by subtracting from both sides.

2x > x + 19 - 7

2x > x + 12

Move x by subtracting from both sides.

2x - x > 12

x > 12

Therefore, x is greater than 12.

Solving 3x + 7 > x + 19

3x + 7 > x + 19

Move 7 by subtracting from both sides.

3x > x + 19 -7

3x > x + 12

Move x by subtracting from both sides.

3x - x > 12

2x > 12

Divide 2 on both sides to get x.

2x/2 > 12/2

x > 6

Therefore, x is greater than 6.

Part 2:

Write an expression for if 3 was open inequality and line continues past negative 5.  This may not be correct due to the vagueness of what it's asking.

Expression: x < -5 < 3

x indicates all real numbers less -5

3 is open inequality and is the greatest

The 2nd question is like really vague.

Let x represent number of rabbits and y represent number of chickens.

We have been given that Jessie told her friends that there were total 30 heads for both animals. This means that there are total 30 animals.

[tex]x+y=30...(1)[/tex]

[tex]y=30-x...(1)[/tex]

We have been given that Jessie only had chicken and rabbits. We know that a rabbit has 4 legs, so total number of legs for x rabbits would be [tex]4x[/tex].

We know that a chicken has 2 legs, so total legs of y chickens would be [tex]2y[/tex].

Since all animals has 76 legs in all, so we can represent this information in an equation as:

[tex]4x+2y=76...(2)[/tex]

Upon substituting equation (1) in equation(2), we will get:

[tex]4x+60-2x=76[/tex]

[tex]2x+60=76[/tex]

[tex]2x+60-60=76-60[/tex]

[tex]2x=16[/tex]

[tex]\frac{2x}{2}=\frac{16}{2}[/tex]

[tex]x=8[/tex]

Therefore, Jessie have 8 rabbits on his farm.

Number of chickens would be [tex]y=30-x\Rightarrow 30-8=22[/tex].

Therefore, Jessie have 22 chickens on his farm.

No map given but it shouldn't matter.

E is the 5th letter, L the 12th.

Start at S(6,12).  End at E(10,5)

The vector between them, E-S=(4,-7)

Each unit is 1/16 of a mile, though that probably doesn't matter that much.

Doug has to stay on the grid, so has to run |4|+|7|=11 units.  At 30 mi/hr that takes (11/16)/30 =  0.022916 hours.

Bert can go diagonally, so flies √(4²+7²)=√65 ≈ 8.06 units.  At 20 mi/hr that takes (8.06/16)/20 = 0.025194 hours.

Answer:  Doug wins

Why? Because it's quicker to cover 4+7 at 30 mph than it is to cover √(4²+7²) at 20 mph.  That is, Doug is 1.5 times faster and the 1.5 times the diagonal distance is more than the grid distance.

Answer:

Doug wins. He finishes in 1.38 minutes. Bert takes 1.51 minutes.

Step-by-step explanation:

Each city block is a square 1/16 mile by 1/16 mile.

From 6th Av and L Street to 10th Av and E Street, they need to go 4 avenues and 7 streets over. These two distances along blocks are the legs of a right triangle. The right triangle has legs of length 4 * 1/16 mile and 7 * 1/16 mile.

leg1 = 4 * 1/16 mile = 0.25 mile

leg2 = 7 * 1.16 mile = 0.4375 mile

The hypotenuse of the right triangle can be calculated by the Pythagorean theorem.

a^2 + b^2 = c^2

(0.25 mile)^2 + (0.4375 mile)^2 = c^2

c = 0.50389

The direct distance from one corner to the other is 0.50389 miles.

The bird travels this distance since the bird can fly above the streets.

The dog has to travel along the legs of right triangle by running in the streets and avenues. The dog travels 0.25 mile + 0.4375 mile = 0.6875 miles

Now we need to see what takes less time:

Bird: distance of 0.50389 miles at 20 mph, or

Dog: distance of 0.6875 miles at 30 mph

We start with the formula for speed:

speed = distance/time

s = dt

Now we solve it for time:

st = d

t = d/s

Time equals distance divided by speed.

Now we find the times for the bird and for the dog.

Bird:

t = d/s = (0.50389 mi)/(20 mi/h) = 0.02519 hours = 1.51 minutes

Dog:

t = d/s = (0.6875 mi)/(30 mi/h) = 0.0229 hours = 1.38 minutes

The bird takes 1.51 minutes, and the dog takes 1.38 minutes.

The dog takes less time to get there, so the dog wins.

Answer:

The value of x is 2

Step-by-step explanation:

Diameter = 2r -------------------------------------------------------------------(1)

where r is the radius

The value of the diameter = 32 m   and  radius is given to be 4(x+2)

substitute the above into equation (1)   and then solve for x

32  =  2 [ 4(x + 2)]

first open the inner bracket

32 = 2[4x + 8}

then open the outer bracket

32 = 8x + 16

subtract 16 from both-side of the equation

32 - 16 = 8x +16 - 16

16 = 8x

Divide both-side of the equation by 8

16/8  = 8x/8

2 = x

x = 2

Therefore, the value of x is 2

A straight line makes a 180 degree angle. Since we know one side is 54, just subtract 54 from 180.

Answer:

The answer is A.

Step-by-step explanation:

It factors to (x+12)(x-12)

This is the same as (x-12)(x+12) as we can multiply two expressions in any order we want. This is like saying 7*5 is the same as 5*7

I used the difference of squares rule to factor x^2 - 144. It might help to write x^2 - 144 as x^2 - 12^2, then compare it to a^2 - b^2 = (a-b)(a+b)

If you view the triangle face in halves, the bottom leg is  units as 8/2 = 4. The hypotenuse is 5 units given in the centre of the triangular prism. You can then use the Pythagorean theorem to calculate that the height is 3.  

Answer:

58.4 Degrees

Step-by-step explanation:

Look at the attachment

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The measure of the third angle of a triangle is 58.4°.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

The sum of all the angle of the traingle is always 180°.

31.8° + 89.8° + x = 180°

x = 58.4°

Hence, the measure of the third angle of a triangle is 58.4°.

Answer:

C

Step-by-step explanation:

Answer:

D cannot be used. first 3 are correct

Step-by-step explanation:

Consider the triangle ABD,

Here,

AB = 5

BD = 15

AD = s

As we know,

In a triangle, the sum of lengths of two sides is greater than the third side.

So,

[tex]5 + 15 > s[/tex]

[tex]15 + s > 5[/tex]

[tex]s + 5 > 15[/tex]

Now,

To satisfy the equation, the value of s can possibly be 11, 12, 13, 14, 15, 16, 17, 18, 19

Answer: the value of s is 17 units

Step-by-step explanation:

Answer:

arc BAD = 244°

Step-by-step explanation:

The sum of the angles around the centre of the circle = 360°, thus

∠APD = 360° - (136 + 74 + 42)° = 360° - 252° = 108°

The angle at the centre is equal to the arc that subtends it, thus

arc BAD = arc BA + arc AD = 136° + 108° = 244°

The requried measure of arc BAD on circle P is given as  244°.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

The Arc of the whole circle measures, 2π = 360°,
Angle ∠APD is given as

∠APD = 360° - (136 + 74 + 42)°
∠APD   = 360° - 252° = 108°

The angle at the center is equal to the arc that subtends it, thus

Arc BAD = Arc BA + Arc AD
Arc BAD = 136° + 108° = 244°

Thus, the requried measure of arc BAD on circle P is given as  244°.

Its pretty obvious since the other answer has 1 star, but its B. I got it right on khan academy:)

The correct statement is option A)

Function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given here: The graph of the function h(t)=0.32-[tex]0.5^t[/tex]

which can be re written as h(t)=  [tex]\frac{8}{25}[/tex] - [tex]\frac{1}{2} ^t[/tex]

Thus clearly as the value of t increases or as we move from negative to positive values the graph of the function tends towards zero and is negative for negative values of t.

For instance, at t= -4 we have

8/25 - 16=15.68

and at t=4 we have

8/25 - 1/16 =0.2575

And it intercepts the x-axis at (1.644,0)

Clearly h(t) is smaller for negative values of t and higher for higher values of t and thus has a upward curvature when we input the values from left to right.

Hence, The curve should slowly bend towards x-axis and option A is the correct answer because the graph is higher values for higher values of t.

Answer: The answer is 9

Step-by-step explanation:

It is 9 because 3x3x3x3 is basically 9x9 and 9x9 is 81, so 81 is the numerator. Then we gat to the denominator, which is 3x3 and 3x3 is 9. So the new fraction you get is 81/9, which is basically 81 divided by 9. 81 divided by 9 is 9.

Answer:
