VMariaS [17]3 years ago

3 0

Answer:

f= 0.7

Step-by-step explanation:

Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f

Then, you are left with: 5f-3 = 1/2

Then you subtract by three on both sides to get: 5f=3.5

Finally, divide by 5 on both sides to get: f=.07

If ∠RST = 65, m∠QST = 2x, and m∠QSR= 3x – 10, what is the value of x?

Rina8888 [55]

Answer:

x = 15

Step-by-step explanation:

Given: ∠RST = 65, m∠QST = 2x, and m∠QSR= 3x – 10

∠QST + ∠QSR = ∠RST

Plug in

2x + 3x – 10 = 65

Combine like terms

5x - 10 = 65

Add 10 to both sides

5x = 75

Divide both sides by 5

x = 15

So answer: x = 15

The games have been sorted into video gunes and board games. The number of video games is 28 less than 6 times

vladimir2022 [97]

There were 14 board games

<h3><u>Solution:</u></h3>

Let "v" be the number of video games

Let "b" be the number of board games

Given that The number of video games is 28 less than 6 times the number of board games

number of video games = 6 times the number of board games - 28

v = 6b - 28 ------ eqn 1

Also given that The games are 80% video games

So this means out of total games(video + board) , 80 % are video games

video games = 80 % of (video + board games)

v = 80 % of (v + b)

$v = 80 \% \times (v + b)$

$v = \frac{80}{100} \times (v + b)\\\\v = 0.8(v + b)\\\\v = 0.8v + 0.8b\\\\0.2v = 0.8b\\\\v = 4b$

Substitute v = 4b in eqn 1

4b = 6b - 28

-2b = -28

b = 14

Thus there were 14 board games
