J. -8 is the correct answer
If we break down the problem if basically gives the answer:
five times the quotient of some number and ten
5 times (any variable) divided by 10
The answer is B. The answer isn't A because you have to go in order of what the question states. It didn't say ten first. It can't be C or D because those are not quotients.
Is there an image so I can see
An easy way to do this is by using the simplest equations you can:
x + y and x - y
(3, 5) is (x, y). all you have to do is plug those into your equations and get a result, so:
x + y = 8
(because 3 + 5 = 8)
x - y = -2
(because 3 - 5 = -2)
and those can serve as your system of equations.
you can check it by solving by substitution:
x - y = -2
x + y = 8
solve one of the equations for a single variable:
x = y - 2
plug it into the second equation:
(y - 2) + y = 8
y - 2 + y = 8
2y - 2 = 8
2y = 10
y = 5
then plug that result back into the equation:
x + y = 8
x + 5 = 8
x = 3
Answer:
7x + 9
Step-by-step explanation:
5x + 2x = 7x
4 + 5 = 9
