1.06(12.95+x)=31.27 solve for x

Step-by-step explanation:

1.06(12.95 + x) = 31.27

Multiply the terms in the bracket

That's

13.727 + 1.06x = 31.27

Subtract 13.727 from both sides

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

Divide both sides by 1.06

That's

We have the final answer as

Hope this helps you

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

the solution is h=10 because you add 9 to each side of the equation.
