Find the value of x and y.
(5y – 4)º
3yº
(2x + 13)º

x = 28

y = 23

Step-by-step explanation:

3y + 5y-4 = 180*

8y = 184

y = 23

*This equation can be written because the same-side interior angle to the (5y-4) angle equals '3y' due to being vertical angles

3y = 2x + 13  (This equation is justified because angles are 'corresponding')

3(23) = 2x + 13

69 = 2x + 13

56 = 2x

x = 28

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

you never say the total so we cant find the percentage used for petrol
