(8v^2+6v+5)+(9v^2+v+6)

lisabon 2012 [21]

Answer:

= 17 v^2 + 7v + 11

Step-by-step explanation:

Given that:

= (8v^2+6v+5)+(9v^2+v+6)

by removing brackets

= 8v^2 + 6v + 5 + 9v^2 + v + 6

Addin like terms:

= (8v^2 + 9v^2) + (6v + v)+ (5 + 6)

= 17 v^2 + 7v + 11

A collection of dimes and quarters is worth $6.50. There are 35 coins in all. How many dimes are there. Work it out with two equ

zimovet [89]

D + q = 35....d = 35 - q
0.10d + 0.25q = 6.50

0.10(35 - q) + 0.25q = 6.50
3.50 - 0.10q + 0.25q = 6.50
-0.10q + 0.25q = 6.50 - 3.50
0.15q = 3
q = 3 / 0.15
q = 20 <=== 20 quarters

d + q = 35
d + 20 = 35
d = 35 - 20
d = 15 <=== 15 dimes
