Answer: 10, 11, & 12
<u>Step-by-step explanation:</u>
Let x represent the age of the youngest child.
Their ages are consecutive so,
Youngest: x
Middle: x + 1
Oldest: x + 2
The age of the Youngest squared (x²) equals 8 times the Oldest [8(x + 2)] plus 4.
x² = 8(x + 2) + 4
x² = 8x + 16 + 4
x² = 8x + 20
x² - 8x - 20 = 0
(x - 10)(x + 2) = 0
x - 10 = 0 or x + 2 = 0
x = 10 or x = -2
Since age cannot be negative, x = -2 is not valid
So, the Youngest (x) is 10
the Middle (x + 1) is 11
and the Oldest (x + 2) is 12
Well if you take 468 and divide it by 18 you get 26 that 26mpg take 754 divide it by 26 and you get 29 and that's how many gallons he used
Answer:
a
Step-by-step explanation:
The correct answer is a. 47.10 - 25 + d = 97.43.
This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.
Also, Tina made a deposit of an amount that she can't remember. A deposit is adding a certain amount of money, so you have to +d.
This rules out option B.
The only option left is option A, which makes complete sense.
