Step-by-step explanation:
<u>It looks like</u>
<u>Cross-multiplication:</u>
- 4m(m+7) = 9*18
- 2m(m+7) = 9*9
- 2m^2 + 14m = 81
- 2m^2 + 14m - 81 = 0
Here is the quadratic equation

Answer:
$299
Step-by-step explanation:
Given that 70% is $230 you can divide this by 7 to get 10%.
10% is 23. The remaining percentage we need is 30.
Soo 10% x 3 = 30%. (23x3)
23 x 3 = 69.
69 + 230 = $299
Answer:
36
Step-by-step explanation:
9+9+9+9=36
Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
