Isolate the y

add 7 to both sides

y - 7  = 21

y - 7 (+7) = 21 (+7)

y = 21 + 7 

y = 28

28 is your answer

hope this helps

Which of the following numbers are written correctly in expanded form? Select TWO that apply.
ivolga24 [154]

Answer:

C is correct, D might be correct if you forgot 000 at the end of the question.

Step-by-step explanation:

005  = 5x1  so A is incorrect

945 = 9x100 +  4x10 +   5x1 so B is incorrect

15.859 = 1x10 +  5x1 +  8/10 +  5/100 +  9/1000 +  so C is correct

973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect

7.935 x 10 to negative 5 power
Effectus [21]

Answer:

0.00007935

Step-by-step explanation:

7.935 x 10 to negative 5 power can be written as:

7.935 x 10^(-5)

7.935*10^{-5}\\\frac{7.935}{10^5}

A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

\frac{7.935}{100000}\\

When dividing by tens, move the decimal to the left by the amount of 0's

So our answer is 0.00007935
