Answer:
a = -2
Step-by-step explanation:
7a + 10 = 2a
subtract 7a from each side
7a-7a+10 = 2a-7a
10 = -5a
divide by -5
10/-5 = -5a/-5
-2 = a
check
7 (-2) +10 = 2(-2)
-14 + 10 = -4
-4 = -4
Answer:
15 box of cookies =$9
1 box of cookie = $9/15=$0.6
((5x2)+5.5+(6x3)+6.5+(7x5)+(7.5x4)+(8x4))/20
137/20
= 6.85
M = 9
o = 7
m + 0 = 9 + 7 = 16
Hence, the answer is 16.
