Answer:

Angles 2, 4, 6 & 8 are 118 degrees and angles 1, 3, 5 & 7 are 62 degrees.

Step-by-step explanation:

∠4 ≅ ∠2 by the Vertical Angle Theorem.

∠4 ≅ ∠8 by the Corresponding Angle Theorem.

∠4 ≅ ∠6 by the Alternate Exterior Angle Theorem.

∠4 is supplementary to ∠1 and ∠4 supplementary to ∠3 by the Linear Pair Postulate.

∠4 is supplementary to ∠5 because ∠4 ≅ ∠2 (explained above) and ∠2 supplementary to ∠5 by the Same-Side Interior Angle Theorem.

∠4 is supplementary to ∠7 by the Same-Side Exterior Angle Theorem.

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

Answer:

x = -40

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Multiply 5 to both sides of the equation:

(x/5) * 5 = (-8) * 5

x = -8 * 5

x = -40

x = -40 is your answer.

Answer:

[tex] \mathbb= > \frac{x}{5} = - 8[/tex]

[tex]\mathbb = > x = - 8 \times 5[/tex]

[tex]\mathbb = > x = - 40[/tex]

Answer:

3 x - 2 y = 8

y = 3/2 x - 4     rearranging

y = m x + b       standard equation for line

m' = - 2/3    for perpendicular line    m m' = -1

y = - 2/3 x + b

b = y + 2/3 x = 2 + 2/3 * -3 = 0       substituting given values

y = 2/3 x       required line

Answer:

1st number is 64

Step-by-step explanation:

Lets start by making the words into equations.

So the 1st plus the 2nd is 75:

1st+ 2nd= 75

Now the tricky part. The 1st is 9 more than 5 times the 2nd. The key word 'times' means multiplication, we we will have 5 x 2nd somewhere in our equation. The '1st is 9 more than' part tricks us into thinking we will have 1st plus 9, BUT WE WON'T because it isn't 9 more, its 9 more THAN. This means we will get.

1st= 5 x 2nd +9

To make this a little cleaner, I will have the 1st = X and the 2nd= y.

x+y=75

x=5y+9

We can substitute the bottom equation into the top equation.

5y+9+y=75

Combine like terms

6y+9=75

Solve for Y by getting y alone.

6y+9=75

6y=66

y=11

Then we can take our value of y and plug it back into either equation to solve for X. The top equation is the easiest.

x+11=75

Isolate x to solve for x

x=64

And we established that x= the 1st number, so the 1st number is 64

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.

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:

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!

Step-by-step explanation:

f(x) = x² , then

f(3.5) = 3.5² = 12.25

which means the area of a square with a side of length 3.5 units is 12.25 units²

The area of a square with a side of length 3.5 units is 12.25 square units.

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Given that, the area for any square is given by the function f(x) = x², where x is the length of a side of the square

f(x) = x²

f(3.5) = 3.5²

f(3.5) = 12.25

Hence, The area of a square with a side of length 3.5 units is 12.25 square units.

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:

4gb

Step-by-step explanation:

$55-$35 =$20

after paying min monthly cost she has $20 left before reaching cap of $55

at $5 per gb she can buy 4 gb for $20

The number of gigabytes she can use while staying within her budget less than 4 gigabytes.

It is required to find the umber of gigabytes.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

Let the number of gigabytes be represented be  g

Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $55 per month.

Under $55 = less than (<) $55

According to given question we have,

$35 + $5 × g < 55

35 + 5g < 55

compare like terms and simplify we get,

5g < 55 - 35

5g < 20

g < 20/5

g < 4 gigabytes

Therefore, the number of gigabytes she can use while staying within her budget less than 4 gigabytes.
