Maggie's brother is 6 years younger than four times her age. The sum of their ages is 29. How old is Maggie?

Hi there!

Let m = Maggie's age

Let her brother's age be represented by (4m - 6)

The ages sum up to 29, therefore:

29 = m + (4m - 6)

Combine like terms:

29 = 5m - 6

Add 6 to both sides:

35 = 5m

Divide both sides by 5:

m = 7.

answer:

your answer is: c. 196 7/8 in^3.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
