In the 3rd grade there are 60 kids and ten more girls than boys how many boy costumes and girl costumes will they need

They will need 25 boy costumes and 35 girls costumes.

Step-by-step explanation:

There are x boys.

There are x + 10 girls.

Altogether, there are x + x + 10 students.

Altogether, there are 60 students, so

x + x + 10 = 60

2x + 10 = 60

2x + 50

x = 25  (boys)

x + 10 = 35  (girls)

"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.
