To repeat, we need this:
15+c=17.50.

let's imagine a person who wants to save up for a book that costs 17.50. This person has already saved 15 dollars. how much more does he or she still need to save?
So now we solve:
15+c=17.50
subtract 15 from both sides
15+c=17.50
15-15+c=17.50-15
c=2.5

so the person needs to save 2.5 dollars more.

Jake drove 66 miles in 2/5 hour. what's the unit rate in miles per hour?
Ad libitum [116K]

Answer:

He was going about 26 miles an hour.

Step-by-step explanation:

This is a fraction equal to

66 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

66 miles ÷ 2.5

2.5 hours ÷ 2.5

=

26.4 miles

1 hour

=

26.4 miles

hour

= 26.4 miles per hour

Simplify the following expression: 2x-2y+5z-2x-y+3z. A.x-3y+8z. B.2x-2y+8z. C.3y+8z. D.-3y+8Z Plzzzzzzzz help
Sergeu [11.5K]
Hello there ^ _ ^

2x - 2y + 5z - 2x - y + 3z
The first thing you need to do is to put all the common terms together.

2x - 2x - 2y - y + 5z + 3z
2x - 2x = 0 or nothing so we don't need to put that in the solution
-3y + 8z

The correct option is D
