PLS HELP ME WITH THE QUESTION IN THE PICTURE BELOW :D

I pick d, eleven times the sum of a number and 5,

11(x + 5)
The parenthesis act as a multiplication sign here, 11 Times the sum of a number and 5,
“A number” refers to x.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
