What you do is multiply each number by 35. You get 35 by multiplying the denominators, 7 and 5. You then multiply the numerators and 51 by 35. Once you multiply the numerators you divide that answer by the denominator. Just remember, you multiply all of the numbers by 35 in this equation and ONLY divide the the answer by the denominator if it’s in a fraction.
When you convert them all..
10x+7=51
Now you can isolate the variable.
Subtract both sides by 7 so then it looks like..
10x = 24
Divide both sides by 10
Answer: x = 2 4/10; simplified to 2 2/5
Answer:
A = 53.34 
Step-by-step explanation:
To find the length of the rectangle we solve the PLA triangle
Using the Pythagorean theorem we find the PL side.

Then the length of the rectangle is 12.65
Now we solve the MALU triangle. Where MU = PL
We use the Pythagorean theorem:

Where LU and MA are unknown.
Finally we solve the triangle MPA

Where PM = LU
So:

Now we have two equations and two unknowns. So we solve the system.
(i)
(ii)
We introduce (ii) in (i)

Now we clear MA



MA = 1.3342 (iii)
Now we introduce (iii) in (ii)
1.3342^2 + 4^2 = LU^2
LU = 4.2166
Now we have the length of the rectangle and also its width.
The area A of a rectangle is:
A = l*w
Where
l = length
w = width
A = 4.2166*12.65
A = 53.34
