What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?

Answer:

A. C = (d-ab)/a

Step-by-step explanation:

a(c + b) = d

a(c + b)/a = d/a

c + b = (d/a)

c = (d/a) - b

a(c + b) = d

ac + ab = d

ac = d - ab

ac/a = d/a - ab/a

c = (d/a) - b

Answer:

x=4

Step-by-step explanation:

4x-8+5x=28

9x-8=28

Add 8 to both sides.

9x=36

Divide 9 from both sides.

x=4

Answer:

B:8x-9y=23

Step-by-step explanation:

First find the slope:

m= y2-y1/x2-x1

y2 is 3

y1 is -1

x2 is 1/2

x1 is -4

3-(-1) is 4

1/2-(-4) is 9/2

Now the equation looks likes this:

4 / 9/2

Which can be rewritten as

4*2/9

Thus the slope is 8/9

So the equation is

y=8/9x+b

Now you can substitute to find the y-intercept:

(you can do either (-4,1) or (1/2,3)

I am going to do (1/2,3) since it is easier

3=8/9(1/2)+b

Simplify:

3=4/9+b

Subtract 4/9 on both sides:

b=23/9

Thus the equation is

y=8/9x+23/9

Multiply 9 on both sides:

9y=8x+23

Subtract 8x on both sides:

8x-9y=23

Hope this helps!

equal

is

y = 17x

Step-by-step explanation:

After 1 hour , 17   bicycles are produced

After 2 hours, 34 bicycles are produced

Ratio of bikes produced per hour after one hour is

= no. of bikes produced after 1 hr / no of hours

= 17 / 1 = 17

Ratio of bikes produced per hour after two hours is

= no. of bikes produced after 2 hrs / no of hours

= 34 / 2 = 17

a. equal

b. is

equation of y is

no of bikes produced = (rate/ hour) * no of hours

y = 17 * x

Answer:

a.) 130°

b.) 70°

Step-by-step explanation:

For a given triangle

The sum of all angles on a straight line is equal to 180°

Now,

50° + a = 180°

Subtract 50° from each side we get,

50° - 50° + a = 180° - 50°

a = 130°

Thus, The size of the angle marked a is 130°

The sum of all angles in a triangle is equal to 180°

Now,

b + 50° + 60° = 180°

b + 110° = 180°

Subtract 110° from both side we get,

b + 110° - 110° = 180° - 110°

b = 70°

Thus, The size of the angle marked b is 70°

Answer: The answer is 40.

Step-by-step explanation: 7(7-9) when you use distributive property you will use the 7 outside the parenthesis. Multiply the property inside. then you will get 49-9. Then you will solve it and get the answer 40.

Answer:

1/12

Step-by-step explanation:

find the least common multiple of the denominators.

which is 12

so 1/4=3/12

2/3=8/12

1/2=6/12

so 3/12- 8/12 - 6/12 = -11/12

so there is 1/12th pieces left after they all ate their portions of the pie

(c). The y-intercept is a flat fee.

Answer:

[tex]y = \frac{-2}{3}x + 2[/tex]

Step-by-step explanation:

The first step is convert the given equation in a dependent and independent equation.

[tex]2x + 3y = 12[/tex]

[tex]3y = 12 - 2x[/tex]

[tex]y = 4 - \frac{2}{3}x[/tex]

[tex]x[/tex] is the independent variable and [tex]y[/tex] the dependent variable.

Since both lines are parallel the slope of both equations are the same

[tex]y = \frac{-2}{3}x + b[/tex]

Now for find the unknow [tex]b[/tex] replace the [tex]x[/tex] and [tex]y[/tex] fo the given point.

[tex]4 = (\frac{2}{3})3 + b[/tex]

[tex]4 = 2 + b[/tex]

[tex]4 - 2 = b[/tex]

[tex]2 = b[/tex]

So the final equation is equal to

[tex]y = \frac{-2}{3}x + 2[/tex]

Answer:

Step-by-step explanation:

Given equation

Putting the value of y

Hope it's helpful!

ᔕEᒪEᑎᗩ328

The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14.

An equation is said to be linear if the maximum power of the variable is consistently unity.

More than one variable may be present inside a linear equation.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

-3x = y + 51

At y = -9

-3x = -9 + 51

-3x = 42

x = -14

Hence "The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14".

Answer:

a = 57.5

b = 57.5

Step-by-step explanation:

XY=XZ so c=d

[tex]c = d = \frac{180 - 65}{2} = 57.5[/tex]

Now draw the XH

So angle YXH = 180 — 90 — 57.5 = 32.5

a+YXH=90

a+32.5=90

so a = 57.5

We know that a + 65 + b = 180

So 57.5 + 65 + b = 180

b = 180 — 122.5

b = 57.5

From the above diagram we can conclude that ~

Angle c = Angle a (Alternate interior Angle pair)

Angle d = Angle b (Alternate interior Angle pair)

and,

because their opposite sides are equal.

now, according to linear pair property ~

replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~

(because Angle c = Angle d)

So,

Part A

Extend the table so that we have row and column totals as shown in the diagram below.

There are 986 accurate orders from all four restaurants combined, out of 1125 orders total. The probability of an accurate order is 986/1125. Selecting two such orders, with replacement, means we get a probability of

(986/1125)*(986/1125) = 0.7682 which is approximate.

Now to the question of independence vs dependence. It all comes down to this: Does the first selection affect the second selection? If so, then we have dependent events. Otherwise the events are independent. Because we put the first selection back (or replaced it with an equivalent order), this means the first selection does not alter the second selection. The two selections effectively exists in their own separate universe so to speak.

============================================================

Part B

This time, we aren't putting the order back in the pile. Whatever we select is taken out entirely without replacement. The first selection will affect the second one. The probability of getting an accurate order for the first selection is 986/1125 = 0.8764 while the second selection is slightly different at 985/1124 =  0.8763. This difference is enough to show that we have dependent events. The second event depends on the first.

Note the second fraction has each term drop by 1.

The probability of picking two accurate orders, when replacement is not made, is (986/1125)*(985/1124) = 0.7681 approximately

Answer: 50 * 100 = 5000
