We have 2 angles that are supplementary, so their sum equals 180⁰.

(4x - 10) + (7x - 8) =180

11x - 18 = 180

11x = 198

x = 18

Assuming you want the value of x:

The angles are on a straight line which means they must add up to 180 degrees. Make this into an equation.

(4x - 10) + (7x - 8) = 180

Combine like terms.

11x - 18 = 180

Add 18 to both sides.

11x = 198

Divide both sides by 11.

x = 18

If you want the measurements of the angles, plug x into the angles.

4x - 10 ⇒ 4(18) - 10 = 62°

7x - 8 ⇒ 7(18) - 8 = 118°

A car moves at a speed that allows it to move 45 yards in 5⁄4 of a second. How long will it take a car at the same speed to move
Dimas [21]

First, to make things easier, let's turn 5/4 into a decimal given a second is equal to 1000 milliseconds.

5/4 = 1,25

1,25 * 1000 = 1250 milliseconds = 1.25 seconds


So, we've found that 45 yards can be covered in 1.25 seconds. Now we'll use the rule of 3:

45 - 1.25

80 - x


Now we solve:

(80 * 1.25) / 45 = x

100 / 45 = x

2,22... = x


So, according to our answer, 80 yards can be covered in 2,22 seconds, which in fractions would be:

2,22 =\frac{222}{100} = \frac{111}{50}


Hope it helped,
