Anja simplified the expression StartFraction 10 x Superscript negative 5 Baseline Over Negative 5 x Superscript 10 Baseline EndFraction to StartFraction 15 Over x Superscript 15 Baseline EndFraction. What mistake did Anja make?

Step-by-step explanation:

The given expression is

Anja simplfied to

Anja did well powers, however, she did wrong coefficients, instead of dividing them, she subtracted them as she did with powers.

Therefore, Anja's mistakes is solving coefficients, she must divide.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
