What is the answer to this question?

x = 10, y = 40

Step-by-step explanation:

Given the 2 equations

y = 4x → (1)

2y + 2.5x = 105 → (2)

Substitute y = 4x into (2)

2(4x) + 2.5x = 105, that is

8x + 2.5x = 105

10.5x = 105 ( divide both sides by 10.5 )

x = 10

Substitute x = 10 into (1)

y = 4x = 4 × 10 = 40

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
