ANSWER: 41.66666666666667 = x. Or in a fraction, 41 6/9 = x.

STEP BY STEP:

We know that you want to earn $500. So left start by putting that As our total in the equation.

500=

Next, we know that each pie is $12. To finish our equation we will put 12 next to a variable to put 12 standing for the cost and x (our chosen variable) for the number of pies. Put this next to the equal sign.

500 = 12x

Finally, we want to know how many pies you have to sell. Let's get x by itself. Do this by diving 12 on both sides.

500 ➗12 = 12x ➗12

This leaves us with
41.66666666666667 = x. Or in a fraction, 41 6/9 = x.

How do you solve: 2(7-x)+4x=20
Angelina_Jolie [31]
First expand it
Next subtract 14 - 2x + 4x so it can be 14 + 2x
Next subtract 14 from both sides
Next subtract 20 - 14 so it can be 6
Then divide both sides by 2
And lastly reduce the fraction 6/2 and once u reduce it u have your answer which is x = 3.

If RV=w and SU=w–30, what is the value of w?
gtnhenbr [62]

Answer:

w = 60

Step-by-step explanation:

the midsegment SU is half the measure of side RV , then

SU = \frac{1}{2} RV , so

w - 30 = \frac{1}{2} w ( multiply through by 2 to clear the fraction )

2w - 60 = w ( subtract w from both sides )

w - 60 = 0 ( add 60 to both sides )

w = 60

1.3 lesson help please
Airida [17]

Answer:

1. 125

2. 25

3. 40

4. 39

First question:

(15-10)^2 + (15-5)^2

parentheses first to get 5^2 + (15-5)^2

exponents next to get 25 + (15-5)^2

parentheses again 25 + 10^2

exponents again 25 + 100 = 125

Second question:

simplify the exponents (3 *3) + (4 * 4) + (2 * 2) to get 9 + 16 + 4 = 29

Third question:

simplify in the parentheses 6 1/7 - 1/7 = 6

divide 60 by 6 to get 10

multiply 10 by 4 to get 40!

Fourth question:

simplify the fractions to get 1/3 + 8/3 = 3

multiply the 3 by 13 to get 39

DOES ANYONE KNOW THE ANSWER?????????
givi [52]

There's only information to answer question C.

We can only know that 32 marbles were chosen. (yellow and black)

Why?

To answer the first two questions (a and b), we need to know the total number of marbles, so, we can only answer the last question (c).

We know that 7/10 of the 20 yellow marbles were chosen.

So, calculating we have:

\frac{7}{10}*20=14(yellow)

Also, we know that 18 black marbles were chosen, so, the total of marbles chosen is equal to 32 (yellow marbles and black marbles)

TotalMarbles=14(yellow)+18(black)=32marbles

Have a nice day!
