Answer:

Move the decimal point one space to the right

Step-by-step explanation:

12*10=120 12=12.0 move the decimal one space to the right=120

You can also just add 0 if there isn't a decimal point

13.5*10=135 move the decimal one space to the right

Jason solved the following equation to find the value for x. –8.5x – 3.5x = –78 x = 6.5 Describe how Jason can check his answer.

sweet-ann [11.9K]

Answer: Jason can substitute $x=6.5$ into the equation. The left side of the equation must be equal to the right side of the equation.

Step-by-step explanation:

The equation $-8.5x-3.5x=-78$ must be solved by calculating the value of the variable x:

Add like terms:

$-12x=-78$

Divide both sides by -12:

$\frac{-12x}{-12}=\frac{-78}{-12}\\\\x=6.5$

Once Jason solves for x, he has to substitute $x=6.5$ into the equation and simplify to check his answers.

If his answer is right, the left side of the equation will be equal to the right side of the equation.

Then:

$-12(6.5)=-78\\-78=-78$

$x=6.5$ is a solution of the equation.
