Which phrase is not a way to state the meaning of the expression y-7

"a number subtracted from 7" will be 7 - y.

Step-by-step explanation:

The options for this question are

A. 7 less than a number

B. A number subtracted from 7

C. A number minus 7

D. The difference between a number and 7

The given expression is

As you can observe, the expression two terms which are subtracting. However, it's important to pay attention to the right order of the subtraction. Notice that from a number is being subtracted seven units, so the choice we are looking for has to have the wrong order of the subtraction.

SO, option B has the wrong order of the operation, because states "a number subtracted from 7" which means which is not the case.

Therefore, the right answer here is B.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
