Answer:
She is correct.
Step-by-step explanation:
1/2 and 50% is the same thing
50% is 1/2 of 100
Answer: 1/12
Step-by-step explanation: If you multiply the two factors, you would technically get -1/12, but since there are 2 -'s -*-=+
Answer:
m = {-6, -4}
Step-by-step explanation:
<u><em>Subproblem 1:</em></u>
Set the factor '(6 + m)' equal to zero and attempt to solve:
Simplifying
6 + m = 0
Solving
6 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + m = 0 + -6
Combine like terms: 6 + -6 = 0
0 + m = 0 + -6
m = 0 + -6
Combine like terms: 0 + -6 = -6
m = -6
Simplifying
m = -6
<u><em>Subproblem 2:</em></u>
Set the factor '(4 + m)' equal to zero and attempt to solve:
Simplifying
4 + m = 0
Solving
4 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + m = 0 + -4
Combine like terms: 4 + -4 = 0
0 + m = 0 + -4
m = 0 + -4
Combine like terms: 0 + -4 = -4
m = -4
Simplifying
m = -4
The first thing we must do for this case is to define variables.
We have then:
x = Multiple-choice questions
y = short-answer questions
We write the following system of equations:
2x + 4y = 80
x + y = 25
Solving the system of equations we have:
x = 10
y = 15
Answer:
there are 10 multiple-choice questions
