3. Olivia has $8. Her mother has $4,784. The a
Olivia's mother has is how many times the
amount Olivia has?

598 times

Step-by-step explanation:

4,784 / 8 = 598

598

Step-by-step explanation:

if u are dividing it then is 598

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer: 45
