Answer:
91 scores
Step-by-step explanation:
Let x be the score meg get on fourth test,
Let the total sum of the scores in four test = 45 + 48 + 56 + x (91) = 149 + x
149 + x = 240
x = 91
So to put this in easier words, (45+48+56+91)/4=91
Hence, she should get 91 scores on the fourth test to get an average score of 60.
I hope this helps you, Enjoy!

The answer is 86
Following PEMDAS, which is:
parentheses
exponents
multiplication
division
addition
subtraction
I found that the answer was 86
Answer:
-10.
Step-by-step explanation:
Step 1: Explain/define
This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.
P (Parenthesis)
E (Exponents)
M/D (Multiplication/division, whichever comes first)
A/S (Addition/subtraction, whichever comes first)
This is the correct sequence of steps when solving expressions with multiple operations.
PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."
------------------------------------------------------------
Step 2: Solve.
REMEMBER PEMDAS!
Expression given: 4 × 3 + 2 × 9 - 40
There are no parentheses.
There are no exponents.
There is multiplication, but no division.
4 × 3 + 2 × 9 - 40
12 + 18 - 40
There is addition and subtraction. Remember to solve whichever comes first.
12 + 18 - 40
30 - 40
30 - 40 = -10.
I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.
Please let me know if you have any further questions.

Answers
Answer:
n=2
Step-by-step explanation:
Answer:
The answer is n=2.
Step-by-step explanation:
First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.
Then, add 0.12 to both sides, which now looks like 3.6n=7.2.
Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

John had a total of $150. He purchased a DVD box set which costs $50 as well as a single DVD. He is left with $75. Which equation could be used to find the cost p of the DVD?
150 − 50 + 75 = p
150 + 50 + p = 75
50 + p + 75 = 150
150 + 50 + 75 = p
Answers
--Answer--
50 + p + 75 = 150
--Explanation--
The total number of money he had originally is 150. If he is left with 75, that starts us with 150 = 75 ______.
He spend something that was 50 dollars, so add that to 75 which equals 125.
Subtract 125 from 150 and you get 25. 25 is the cost of the single DVD, so we'll make 25 "p."
The cost of the DVD box set, the single DVD, and how much he is left with equals how much money he had originally.
That would make it 50 + p + 75 = 150.

Mai distributed another group of flyers equally among the five volunteers. Then she remembered that she needed some flyers to give to teachers, so she took 2 flyers from each volunteer. Then, the volunteers had a total of 40 flyers to hang up. How many flyers did Mai distribute to each of the five volunteers originally? The answer is 10, but how do you figure that out? Please leave an explanation of how you got your answer.
Answers
Step-by-step explanation: So, she took 2 from each of the volunteers, and there were 5 volunteers in total. What I did, was I found out how many people were taken in total and given to the teachers, which was 10 (2*5), and then I added it to the total number of flyers still with the volunteers (40), which equals 50. Divide that by 5 (number of groups) and you get 10.

Answers
Answer:
Step-by-step explanation:
1) x +22.5 = 49.25
Subtract 22.5 from both sides
x + 22.5 - 22.5 = 49.25 - 22.5
x = 26.75
Checking: LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS
2) 37.2 = n - 12
Add 12 to both sides
37.2 + 12 = n - 12 + 12
49.2 = n
n = 49.2
3) 55t = 176
Divide both sides by 55
[tex]\frac{55t}{55}=\frac{176}{55}\\\\t = 3.2[/tex]

First number be x Second number be 1-x .According to first condition :-
[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Answers
Hello! I believe that I have the answer.
My answer: The total amount was $47.79.
8% of $37.50 is $3. $37.50 + $3 = $40.50.
18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.
