C) 91%
D) 100%

PLEASE EXPLAIN WHY OR I WILL RATE TWO STARS!

Answers

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%

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

Answers

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.

Step-by-step explanation:

Essentially, because ABCDE and JKLMN are similar, their corresponding sides have a common ratio. To find x, we can simply the ratio between NJ and its corresponding side equal to the ratio of another pair of corresponding sides.

[tex]\frac{BA}{KJ}=\frac{AE}{JN}[/tex]

2/3 a - 1/6 = 1/3

answer this math question asap pls

Answers

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.

the answer is a= 3/4
