Celia simplified the expression - 4x{1-+2). she checked her work by letting x-5 in both expressions. her work for the
original expression is shown below.

I think it is the last one

Step-by-step explanation: if you work it out, it equally 6x-2

6x-2

Step-by-step explanation:

When x=5 the value of the expression is 28

Now we check with each expression given in the options

Plug in 5 for x in each option

So 6x-2 gives us 28 when x=5

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
