John received a 68%, 72%, and 85% on three of his math tests. After his fourth math test he now has a 79% average. What score did he have received on his fourth test?
A) 79%
B) 89%
C) 91%
D) 100%
PLEASE EXPLAIN WHY OR I WILL RATE TWO STARS!
Answer:
68+72+85=225
plus 79 =304 divided by 4 = 76
plus 89 =314 divided by 4 = 78.5
plus 91=316 divided by 4 = 79
so the answer is C
plz brainlest
Answer:
91%
Step-by-step explanation:
(0.68 + 0.72 + 0.85 + x)/4 = 0.79
(2.25 + x)/4 = 0.79
0.5625 + 1/4x = 0.79
1/4x = 0.2275
x = 0.91 = 91%

2/3 a - 1/6 = 1/3
answer this math question asap pls
Answer:
a=3/4
Step-by-step explanation:
1. Get 2/3a by itself.
•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.
•Because you only add and subtract like denominators
This will make it look like:
2/3a - 1/6 = 2/6
Then, add 1/6 to both sides to get 2/3a by itself.
It'll look like this:
2/3a = 3/6
2. Get a by itself.
•Multiply the reciprocal (opposite) of 2/3 to get a alone.
This will look like:
(3/2) • 2/3a = (3/2) • 3/6
a = 18/24
3. Simplify.
Find the largest number that can simplify the equation.
For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.
But the largest number you can divide both sides by is 6.
18 ÷ 6 = 3 and 24 ÷ 6 = 4.

Find the range of the following list of numbers:
62, 59, 59, 61, 70, 120, 62, 70, 62, 65
59
61
69
62
Answer:
The range is 61.
Step-by-step explanation:
The range is the difference between the highest and lowest number. 120 is the highest, 59 is the lowest, you subtract them and get your final answer of 61.

While on a plane, Charlie counted the number of adults, children, and empty seats. 1/5 of the seats were occupied by children.
3/4 of the seats were occupied by adults.
10 seats were empty .
A. How many passenger seats were on the plane
B. Write how you figured it out
Answer:
200 seats
Step-by-step explanation:
Let s = numbers of seats
1/5s = children
3/4 s = adults
10 = empty
The total number of seats = children + adults + empty
s = 1/5s + 3/4s + 10
Subtract 1/5s and 3/4s from each side
s -1/5s -3/4s= 1/5s-1/5s + 3/4s-3/4s + 10
s - 1/5s - 3/4s = 10
Get a common denominator
20s/20 - 4s/20 -15s/20 = 10
Combine like terms
1s/20 = 10
Multiply each side by 20
s/20 *20 = 20*10
s = 200
Answer:
19 seats
Step-by-step explanation:
you take the denominators: 5,4, and 9
then you add them to get 19.
