Answer:
Michelle must get an 80 on her next test to keep her average score.
Step-by-step explanation:
Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:
X / 2 = 80
X = 80 x 2
X = 160
X x 3 = 80 x 3
X x 3 = 240
X = 240/3
x = 80
So, Michelle must get an 80 on her next test to keep her average score.
Answer:
Infinitely many solutions
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
2x+12= 2(x+6)
2x+12= (2)x+(2)6
Step 2- Multiply
2x+12= 2x+12
Since they are equal, they are infinite.
Answer:
The answer is
Step-by-step explanation:
We must find a solution where
Consider the Left Side:
First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get
Which equals
Add the fractions
Simplify the right side by multiplying the fraction
Set both fractions equal to each other
Since the denomiator are equal, we must set the numerator equal to each other
