Answer:
x=21, y= 35
Step-by-step explanation:
3x+7=5x-35
(subtract seven from -35)
3x=5x-42
(subtract 5 from 3)
-2x=-42
(-42/-2= positive number)
x=21
y+75=3y+5
(subtract 75 from 5)
y=3y-70
(subtract 3y from y)
-2y=-70
y=35
It is A
The first one
266yd^2
A = b x h
15.2 x 17.5 = 266
12y-9-(3y-4)-4y+7 =
(9y-5)-4y+7 =
(5y-5)+7=
5y+2
