Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y
2y = 180-5x
Divide by 2
2y/2 = 180/2 -5x/2
y = 90 -5/2 x
Answer:
17 pants and 9 shirts
Step-by-step explanation:
questions like this require you to guess numbers first then adjust them as needed. I originally guessed 20 pants and 6 shirts, however the number was too high, so I put less pants, since they're the higher number. if the number was too low you would use less shirts since they're the lower number. after a couple of tries you'll get
(225 × 17) + (125 × 9) = 4950
but seriously who spends almost 5000 dollars on clothes from one store in one outing, that's so much money
