Answer:

x less 21.5

Step-by-step explanation:

Given : the algebraic expression x - 21.5

a. 21.5 decreased by x

the expression becomes 21.5 - x

b. x more than 21.5

more than means we add , so expression becomes 21.5 +x

c. 21.5 minus x

For minus we use subtraction symbol,

so the expression becomes 21.5 -x

d. x less 21.5

x less 21.5 , we subtract 21.5

so the expression becomes x - 21.5 . that is the given expression

Alina [70]

ANSWER:

Carlos is building a screen door.The width of the screen is 3 feet.

SOLUTION:

Given, Carlos is building a screen door. The height of the door is 1 foot more than twice its width.

And height of the screen door is 7 feet high.

Let the width of the screen door be x feet wide.

Now, according to given information,

Height is 1 foot more than the 2 times of width. Hence we can form a equation as,

7 = 1 + 2x

2x = 7 – 1

2x = 6

x = $\frac{6}{2}$ = 3

Hence, the width of the screen is 3 feet.
