Answer:

<h2>Anja's mistakes is solving coefficients, she must divide.</h2>

Step-by-step explanation:

The given expression is

\frac{10x^{-5} }{-5x^{10} }

Anja simplfied to

\frac{15}{x^{15} }

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.

\frac{10x^{-5} }{-5x^{10} }=-\frac{2}{x^{15} }

Ralph is 3 times as old as Sara in 4 years Ralph will be twice as old as Sara will be then. Find Ralph’s age now.
Xelga [282]

Answer:

3x+4 Ralph is currently 12 years old.

Step-by-step explanation:

You can find the equation by reading the scenario given. When you read it, it says that Ralph is 3 times as old as Sara and since her current age is going to be used to represent x you will first get 3x. That automatically eliminates the second and third choice given. It then says the equation is for Ralph's age in four years which means to add four to the equation. This gives you 3x+4 as your equation.

When something is tripled and then in a few years it is doubled, it is easiest to first try the number that is being added. So in this case the number is four. When you multiply 4 by 3 you get 12. If Sara is 4 she'll turn eight in four years and if Ralph is 12 he'll turn 16 in four years. 16 divided by 2 is 8 which shows you that Ralph is currently 12
