The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
Answer:
26+32=10v
add numbers
58=10v
10v=58
divide both sides by 10
v=5.8
There will be 6 vans needed
58/6=9.6
There will be 10 students in four vans, and 9 students in two vans.
Answer:
Step-by-step explanation:
Eliminate the y terms by adding the equations together:
-10y+9x = -9
10y+5x = -5
——————-
14x = -14
x = -1
y = 0
Answer:
m = 3/4
Step-by-step explanation:
A(3, 7)
B(7, 10)
As we move from A to B, we see x increasing by 4 to 7 and y increasing by 3 to 10. Thus the slope is
m = rise / run = 3/4
