Answer:
$41.33
Step-by-step explanation:
Let the money be x
Game cost = 2/3*x
balance= 1/3*x
x/3= 15.5
Solve for x
x= 15.5*3
x=$46.5
so his money was $46.5
Amount spent on Game
=2/3*46.5
=$31
He spent 2/3 of 15.5 on Jacket
=2/3*15.5
=$10.33
In all he spent =31+10.33 =$41.33
I think the answer is
No
No
Yes
But I'm not sure about the last one
Answer:
Step-by-step explanation:
In this equation what is strange is probably using the letter a as the unknown, but this is a matter of choice we could have calle y or z for that matter. Then we will treat it ans any other equation and solve it.
-11 -5a = 6(5a+4)
-11 -5a= 30a + 24
-11 - 24 = 30a + 5a (placing the unknown a in the rght side and the numbers in the left to solve the equation)
- 35 = 35a
-35/35 = a
- 1= a
