Hello!
Judging by the question you have provided I have figured that the best way to go about finding the solution is by using the distributive property!
This means you will want to distribute the y = -3 into the 2y+7-4y-10 equation.
However, the first step you should take is to simplify the equations.
After simplifying the equations you should come out with the new equation being -2y-3.
You now want to distribute the y=-3 into the equation!
You should get -2(-3)-3. Now solve!
The answer you get should be 3!
Hope this helped!

12 is sq root of 144

(70 -100)/15 = -2 . . . . the z-score of a score of 70
p(z < -2) ≈ 2.3%
A score of 70 would place you in approximately the 2nd percentile.
Prism maybe:)
have a good day!!
