Answer:
q = 
c = 
Step-by-step explanation:
First solve for q:
0.162q + 0.035c = 4
0.162q = 4 - 0.035c (move term to other side)
q = 
(divide both sides by 0.162 to get it away from q)
q = (simplify fraction)
Solve for c:
0.162q + 0.035c = 4
0.035c = 4 - 0.162q (move term to other side)
c = 
(divide both sides by 0.035 to get it away from c)
c = (simplify fraction)
Answer:
Step-by-step explanation:
I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".
Let x be the number.
Ratio is division.
(x-7)/(x+7)=2
Multiply by (x+7) on each side:
x-7=2(x+7) = 2x+14
Add 7 on each side
x=2x+21
Subtract 2
-x=21
x=-21
Answer: 12 - c
Step-by-step explanation:
Really, the expression is 96/8 - c
where 96/8 means The number of questions each child would have gotten if the grandma was fair, and - c means the amount of cookies fewer Cindy received. Simplifying this, makes the expression 12 - c.
