Answer:
y = -10
Step-by-step explanation:
Hey there!
To solve this you first have to distribute the -3 to y and 5. When you do this you get...
-3y - 15 = 15
Add 15 on both sides you get...
-3y = 30
Divide by -3 and you get...
y = -10

Answer:
24.75 = 3*4.50 + x*4.50
x= 2.5 pounds of Granny Smith apples
Step-by-step explanation:
Gala apples = 3 lbs
Granny apples = x lbs
They cost 4.50 a pound
Total cost = 24.75
Total cost = gala apples * cost per pound + granny apples * cost per pound
Substitute in what we know
24.75 = 3*4.50 + x*4.50
24.75 = 13.50 + 4.5x
Subtract 13.50 from each side
24.75-13.50 = 13.50-13.50 + 4.5x
11.25 = 4.5x
Divide by 4.50 on each side
11.25/4.5 = 4.5x/4.5
2.5 =x

Answer:
Step-by-step explanation:
she had $ 24 to spend on 7 pencils....and after buying them she had $ 10.
this means that the total of the pencils was (24 - 10) = $14
and assuming each pencil cost the same price....
14/7 = $ 2 per pencil
or u can set it up as an equation
24 - 7x = 10....with x being the price of a pencil
24 - 10 = 7x
14 = 7x
14/7 = x
2 = x <==
