Find the values of each variable

x = 38°

y = 104°

Step-by-step explanation:

You have to find the value of x and y.

All angles on a straight line are equal to 180° also called supplementary angles.

Step 1: Find y

76 + y = 180° (because supplementary angles)

y = 180 - 76

y = 104°

Step 2: Find x

2x + y = 180° (because supplementary angles)

y = 104°

2x + 104 = 180°

2x = 180 - 104

2x = 76

x = 76/2

x = 38°

Therefore, y = 104° and x = 38°.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

1) is right
