2.about 2 bottles of paint
Answer:
p = 3
q = 4
Step-by-step explanation:
p + 2q = 11 --------------------(I)
p = 11 - 2q
2p + q = 10 --------------------(II)
Substitute p = 11 -2q in equation (II)
2(11 - 2q) + q =10
2*11 - 2q *2 + q = 10
22 - 4q + q = 10
22 - 3q = 10
-3q = 10 - 22
-3q = -12
q = -12/-3
q = 4
Plugin q = 4 in equation (I)
p + 2q = 11
p + 2*4 = 11
p + 8 = 11
p = 11 - 8
p = 3
You have to answer the problem and follow the clues that is shown on you expression
600feet square ( I think)
X = number of dimes
x + 2 = number of nickels
3(x + 2) = number of pennies
10x + 5(x + 2) + 3(x + 2) = 52
10x + 5x + 10 + 3x + 6 = 52
18x = 36
x = 2
x = 2 (number of dimes)
x + 2 = 4 (number of nickels)
3(x + 2) = 12 (number of pennies)
Check:
2(10) = 20 cents in dimes
4(5) = 20 cents in nickels
12(1) = 12 cents in pennies
Total = 52 cents
