A) 79%
B) 89%

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%

Describe, in great detail, how you would put a line into slope-intercept form (y = mx + b) if it wasn't already, so that it would be ready to graph.
Use 2y - 4x = 104 as your example.
Answer:
y=2x+52
Step-by-step explanation:
you would put y to one side so subtract 4x from the side with y and move it to 104
2y=104+4x
Now divide by 2 so you have y alone
y=52+2x
answer y=2x+52
2 is m, and 52 is b

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.

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.
3/4.

Angel and Jayden were at track practice. The track is 2/5kilometers around. Angel ran 1 lap in 2 minutes. Jayden ran 3 laps in 5 minutes. How many minutes does it take Angel to run one kilometer?
pls, help I don't want to fail!!
Answer:
5 minutes
Step-by-step explanation:
if one lap is 2/5 km then you would need to run 2.5 laps to run a km and if it takes 2 minutes to run a lap then you multiply 2 minutes by the number of laps aka 2.5 so 2 times 2.5=5
