Please help me I am so lost

Answer:

x = 64°

Step-by-step explanation:

In a parallel line the opposite angle sides have the same value.

first you have to get the value of the angle beside the 128° angle.

we know the half the circle has 180°. so the rest of the angle must be 180° - 128° = 52°

Now the opposite site of the parallel line its going to be the same.

since now we have the value of the angle.

2x + 52 = 180

2x = 180-52

2x = 128

x = 128/2

x = 64

OR,

You can just cut all the nonsense and write

2x = 128°

because its on the opposite side of the parallel. the value will be same.

so,

x = 128/2

x = 64

Thank me later.

1/4(z +3z)+ 7=−z + 1 please help with this ive been stuck
madam [21]
First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1

Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1

Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6

Divide both sides by 2. You’ll get :
z=-3

John is joining a gym. There is a membership fee of $25 per month and a fee of $2 per workout class he attends. Given this infor
skad [1K]

Answer:

Input variable x: Number of classes he attends.

Output variable y: Monthly cost

Slope: Cost per class, of $2

y-intercept: Membership fee, of $25.

Function: y = 2x + 25

Step-by-step explanation:

This situation can be represented by a function is the following format:

y = mx + b

In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).

We have that:

There is a membership fee of $25 per month and a fee of $2 per workout class he attends.

This means that b = 25, m = 2. So

y = 2x + 25

lukranit [14]
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.

If there bill was 58.65 and they gave a sever a 15% tip, how much did they pay altogether
masha68 [24]

Answer:

<u>$67.43 altogether</u>

Step-by-step explanation:

A 15% percent tip means 15% OF the bill.

15% of 58.65

0.15*58.65=8.7975

You can't really pay $8.7975, so you would round to the nearest one hundredth which is $8.78.

Now you add the $8.78 to $58.65 which will give you $67.43.

I hope that helps!
