Finley has 152 yellow, red, and blue marbles in a bag. He has seven more red marbles than yellow marbles, and three times as many blue marbles as yellow marbles. How many yellow marbles does Finley have? Write an equation to represent this problem. Then solve the equation. A. x + x + 7 + 2x = 152; x = 36 B. x + x + 7 + x = 152; x = 48 C. x + x + 7 + 5x = 152; x = 21 D. x + x + 7 + 3x = 152; x = 29

Answers

X=yellow
X+7=red
3x=blue

So x+x+7+3x=152
5x=145
X=29

Your answer is D.

8374 exponential notation

Answers

Expanded for of 8,374 is:

8000 + 300 + 70 + 4

And writing it with the exponential notation would look like this (for example):

8 * 10^3 + 3 * 10^2 + 0.7 * 10^2 + 0,04 * 10^2

Hopefully that's what you meant :)

what does that mean then what do we need to do

Toby sells nachos at the baseball concession stand. each serving if nachos contains about 3 1/3 onces of chips. which is the best estimate of the number of servings of nachos Toby could make from a 51 5/8 once bag of chips?

Answers

(51 5/8 ) / (4/3)= 1239/32
or 38 and 23/32 so you could round up to 39 servings or down to 38 it probably tells you what you should do in the instructions.

Mathematically 23/32 is greater than .5 so you should round up, but then again logically you can have an imaginary portion of nachos. 

Final answer:

To find the best estimate of the number of servings of nachos Toby could make from a 51 5/8 ounce bag of chips, divide the weight of the bag by the weight of each serving. Toby could make about 177 servings of nachos from the bag.

Explanation:

To find the best estimate of the number of servings of nachos Toby could make from a 51 5/8 ounce bag of chips, we need to divide the total weight of the bag by the weight of each serving. The weight of each serving is 3 1/3 ounces, which is the same as 10/3 ounces. We can divide 51 5/8 by 10/3 to find the number of servings.

Converting the mixed number to an improper fraction, 51 5/8 is equivalent to 413/8. When we divide 413/8 by 10/3, we can multiply the numerator and denominator of the first fraction by the reciprocal of the second fraction: 413/8 multiplied by 3/10. This gives us (413 x 3) / (8 x 10) = 1239/80.

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 7. Dividing 1239 by 7 gives us 177, and dividing 80 by 7 gives us 11. Therefore, Toby could make about 177 servings of nachos from the 51 5/8 ounce bag of chips.

How can you decide if finding common multiples or common factors is helpful in solving problems

Answers

Suppose, John arranges stack of Gold and Silver coins in such a way that each stack either contains Gold or contains Silver coins only.

He also tries to arrange them in the least area.

Here, the number of coins in each stack is the common factor of number of Gold and Silver coins.

If we find the highest common factor, then the area occupied by the coins will be least.

Hence, in this situation, we have to find the common factor.

Suppose, George and David are walking along the circular pathway of a park with different speeds.

The problem is to find the time after which they will meet again at the starting point.

Clearly, here the required time is the common multiple of independent time taken by both.

it depends if you like working with big numbers or not. if you are working with large numbers and you want to bring them down you can use factors. multiples are easier to work with when multiplying to cancel out and make your sum easier

Answers

No, the number would remain positive since you have already  mentioned the word "depth". Using a negative umber just wouldn't make sense, nor would it add any beneficial information too the answer.

Don't put the negative sign even though the problem is negative number.
