<span>Equation:
0.15x + 0.10(5-x) = 0.11*5
---
Multiply thru by 100:
15x + 10*5 - 10x = 11*5
---
5x = 5
x = 1 liter (amt. 15% oj needed)
----
5-x = 4 liters (amt of 10% oj needed)

A.
7 times number of cats=pay
if pay=49 then
7 times number of cats=49
divide both sides by 7
number of cats=7
da equaton can be
c=number of cats
7c=49
he fed 7 cats
B.
7c=49
divide both sides by 7
equality property of division
(7c)/7=49/7
math fact
(7/7)c=7
1c=7
identity property of division
c=7
identity property of multiplication
7 cats
C. 7 cats
You would need to do 48×2=96 pages an hour .it would be 96 pages an hour because for half an hour it is 48 pages so you need to do times two to make it one full hour.i hope this helps if you dont get how I explain it please tell me or if you already have an answer
