We are asked to solve the following one-step equation.
We solve the equation by solving for x. We must isolate the variable by performing the inverse operation.
x is being multiplied by 8 (8x = 8*x). The inverse operation of multiplication is division. Divide both sides of the equation by 8. This eliminates the 8 on the right side of the equation so only x remains.
We can check our answer by substituting it back into the original equation.
This checks out, so we know our answer is correct and x is equal to <u>-13.</u>
All are congruent. Congruent means identical in size or shape. the different markings on the two shapes show that they are congruent. I can’t fully see number 10 so I can’t say it that one is or not
