Answer:
13a
Step-by-step explanation:
9a + 3a + a = 13a
Step-by-step explanation:
The slop is M= 1÷x-y-xy
F(x)=2x
I would write that since x represents the weeks and we know that she watches two movies a week
the length is given and i got the width as 8 so you just add up all the sides and i got 40
Answer:
8x = 32
x = 4
y = 6
Step-by-step explanation:
2.5y + 3x = 27
5x – 2.5y = 5
_____________
8x = 32 (equation obtained after adding the two equations)
x = 32/8
x = 4
Plug x = 4 in 2.5y + 3x = 27
2.5y + 3*4 = 27
2.5y + 12 = 27
2.5y = 27 - 12
2.y5= 15
y = 15/2.5
y = 6
