Answer:
a) the ratio is 9:4
b) Hilda did save $16.
Step-by-step explanation:
Let's define the variables:
C = Cheryl's savings.
H = Hilda's savings.
We know that:
(1/3)*C = (3/4)*H
We also know that Cheryl saved $36, then we have:
C = $36
Now we can replace that in the above equation to get:
(1/3)*$36 = (3/4)*H
$12 = (3/4)*H
$12*(4/3) = H = $16
Then Hilda did save $16.
And the ratio between of Cheryl's savings to Hilda's savings is:
36 : 16
We can simplify this if we divide both by 2.
(36/2) : 16/2
18 : 8
Again, we can divide both by 2:
(18/2) : (8/2)
9 : 4
Then the ratio is 9 : 4

Step-by-step explanation:
Let's solve your equation step-by-step.
6(3x+5)=7(2x+2)
Step 1: Simplify both sides of the equation.
6(3x+5)=7(2x+2)
(6)(3x)+(6)(5)=(7)(2x)+(7)(2)(Distribute)
18x+30=14x+14
Step 2: Subtract 14x from both sides.
18x+30−14x=14x+14−14x
4x+30=14
Step 3: Subtract 30 from both sides.
4x+30−30=14−30
4x=−16
Step 4: Divide both sides by 4.
