Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55
Answer:
its A
Step-by-step explanation:
not gonna explain it cause I dont have to ._. plus it wasnt that hard
5y and 155 create a straight line so:
5y + 155 = 180
5y = 25
y = 5
5y and 13x create a 90 angle so:
5y = 5(5) = 25
25 + 13x = 90
13x = 65
x = 5
Hope this helps :)
Answer:
m^3 + 2 3/4
Step-by-step explanation:
Change the order
7m^3 - 6m^3 + 2 3/4
m^3 + 2 3/4
