Answer:
8.52
Step-by-step explanation:
you have to add all of the amounts that were spent which is 631 and then use proportions to find it. 631 x 1.35 devided by 100
.18 x 67.45 = 12.14 so 67.45 + 12.14 = 79.59
Answer:
D
Step-by-step explanation:
To determine the roots equate the factors to zero, that is
(x + 2)(x² + 7x + 10) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x² + 7x + 10 = 0
(x + 2)(x + 5) = 0
x + 2 = 0 ⇒ x = - 2
x + 5 = 0 ⇒ x = - 5
roots are x = - 5 and x = - 2 with multiplicity 2
Step-by-step explanation:
The answer is 40.5 because 117/6=19.5 19.5+21=40.5
