Thanks for posting your question here. The answer to the above problem is x = <span>48.125. Below is the solution:
</span>
 x+x/7+1/11(x+x/7)=60 
x = x/1 = x • 7/7
x <span>• 7 + x/ 7 = 8x/7 - 60 = 0
</span>x + x/7 + 1/11 <span>• 8x/7 - 60 = 0
</span>8x <span>• 11 + 8x/ 77 = 96x/ 77
</span>96x - 4620 = 12 <span>• (8x-385)
</span>8x - 385 = 0
x = 48.125

Answer:

Option (a) is correct.

x = 48.125

Step-by-step explanation:

Given:  x+\frac{x}{7}+ \frac{1}{11}(x+\frac{x}{7})=60

We have to solve for x,

Consider the given expression x+\frac{x}{7}+ \frac{1}{11}(x+\frac{x}{7})=60

First solving for brackets, we get,

x+\frac{x}{7}=\frac{7x+x}{7}=\frac{8x}{7}

Put , we get,

x+\frac{x}{7}+ \frac{1}{11}(\frac{8x}{7})=60

Simplify, we have,

x+\frac{x}{7}+(\frac{8x}{77})=60

Taking LCM(7,77) = 77

We have,

\frac{77x+11x+8x}{77}=60

Simplify, we have,

\frac{96x}{77}=60

Multiply both side by 77, we have,

96x = 60 \times 77

96x =4620

Divide both side by 96, we have,

x=\frac{4620}{96}=48.125

Thus, x = 48.125

Option (a) is correct.

Okay here is another math problem I'll give a brainliest for the right answer!
Sliva [168]
To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:

2 x 2 = 4

8 x 8 = 64

64 + 4 = 68

Your answer should be 68 ft.^2
