Expression equivalent to

cestrela7 [59]

Answer:

$7

Step-by-step explanation:

To solve this one we will subtract how much he spends from what he has.  At the start he had 19 and then spent 8 meaning he now has 8 less than when we started so 19-8 is 11.  He now as 11 dollars, then he spend another 4 meaning we have to subtract another 4 dollars.  11-4 is 7.  So he as 7 dollars left at the end.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Ill give a brainliest <br> i need help its due today
aliya0001 [1]

Answer:

w=15

Step-by-step explanation:

-24=-3w+21

We move all terms to the left:

-24-(-3w+21)=0

We get rid of parentheses

3w-21-24=0

We add all the numbers together, and all the variables

3w-45=0

We move all terms containing w to the left, all other terms to the right

3w=45

w=45/3

w=15
