"keep-change-flip" is a strategy used to dividing fractions.
always change the mix fraction to a improper fraction and you slove.
I'll do the first one and the rest is basically done the same way.
for the last fraction equation I cross multiply the 4 divided into 4 gives you 1 and the 3 divided into 21 gives you 7.

Bella has a stack of 41 bills (ones, fives, and tens) in an envelope. She has 3 less tens than fives and the quantity of ones doubles the number of fives. Write and solve an equation to determine how many of each bill type she has
Answer:
x+(x-3)+(2*x)=41
Step-by-step explanation:
We know that the other two bills are based of of a constant value for fives. Therefore, the fives can be x. There are 3 less tens than fives, so the number of tens equals x-3. We double the number of fives to get the number of ones, so the number of ones equals 2 times x. When we add all 3 of those together, we get our total number of 41. If you want to solve, you have to solve for x, then you can plug it back into the formula. I hope this helps!

Abigail has a bag that contains pineapple chews, lemon chews, and watermelon
chews. She performs an experiment. Abigail randomly removes a chew from the bag,
records the result, and returns the chew to the bag. Abigail performs the experiment
35 times. The results are shown below:
A pineapple chew was selected 20 times.
A lemon chew was selected 7 times.
A watermelon chew was selected 8 times.
Based on these results, express the probability that the next chew Abigail removes
from the bag will be a flavor other than watermelon as a decimal to the nearest
hundredth.
Answer:

A park has a grassy section that covers 2 1/3 acres. Denny mowed half of the grassy section. What is the number of acres that Danny mowed?
Answer:
7/6 (1 1/6)acres
Step-by-step explanation:
The grassy section covers 2 1/3 acres overall. To find half of that, we divide it by two because half of an amount or object is one of the two equal parts that together make up the whole amount or object.
To turn a mixed number (in this case, 2 1/3) into an improper fraction, multiply the whole number with the denominator of the proper fraction.
2*3 = 6Add the numerator to this product to obtain the numerator of the improper fraction.
6 + 1 = 7
so the improper fraction is 7/3
then we multiply that fraction by 1/2 because we are trying to find half of the overall section
7/3 * 1/2 = 7/6
A women buys 23 pounds of potatoes. She gives 10% of them to a neighbor and 15% of them to her mother. How many pounds dose she have left?
Answer:
= 17.25 pounds (Answer)
Step-by-step explanation:
Potatoes she bought = 23 pounds
Amount she gave outsiders= 10+15=25%
= 23×25/100= 23/4=5.75 pounds
Potatoes left with her= 23 — 5.75
= 17.25 pounds (Answer)
Answer:
17.25 pounds
Step-by-step explanation:
10% of 23 is 2.3
15% of 23 is 3.45
Add them together you get 5.75
Subtract 5.75 from 23
Answer is 17.25

Answer:
1) Yes, it is rational.
2) Yes, it is rational.
3) There are three repeating digits.
Step-by-step explanation:
Lets solve them in order.
1) First lets see what the characteristics of a rational number are. We know that, to be a rational number, a number must either:
Can be expressed as a fractionRepeatAre integersAnd terminateAn irrational number is a number that never repeats or ends. They are also not integers, but we will focus on the never repeats or ends part.
So, lets look at it. Does 0.147 repeat, terminate, be expressed as a fraction, and is it an integer? Well, its not an integer, it doesn't repeat, and it isn't a fraction. However, it does terminate, which means it is rational.
2) Is 0.147 repeating a rational or irrational number. Remember, we need to see if it terminates, repeats, is an integer, or is a fraction. Well, it doesn't terminate, it is not a fraction, and it is not an integer. However, it does repeat. That means that it is a rational number.
3) Now, to figure out how many repeating digits there are. In math, we know that the line above the numbers in the decimal place means that they repeat. So simply find out how many digits are below that line. Well, we see that 1, 4, and 7 are under the line. In total that is three digits. So the answer is 3.

Write an equation for the description.
The length of a rectangle is twice its width. The perimeter of the rectangle is 130 feet.
Answer:
2x + 4x = 130
x = 21.7 feet
Step-by-step explanation:
Width: x
Length: 2x
2x + 2(2x) = 130
6x = 130
x = 130/6
x = 21.7 feet
Sarah's grandmother has a square blanket that covers an area of 25 square feet. Sarah wants to put a string of pearls around the sides of the blanket. How many feet long will the string of pearls have to be for Sarah to complete the job?
Answer:
20 ft
Step-by-step explanation:
area of square = (side)^2
area of square = 25 ft^2
(side)^2 = 25 ft^2
side = 5 ft since (5 ft)^2 = 25 ft^2
The side of the square measures 5 ft.
All around the square is the perimeter.
perimeter = 4 * side
perimeter = 4 * 5 ft
perimeter = 20 ft
Answer: 20 ft

Find the slope and intercepts of 3x + 4y = 12. Sketch a graph.
The slope of 3x + 4y = 12 is m = -3/4
To get the slope, you must use the slope-intercept form y = mx + b to find the slope.
The x-intercept of 3x + 4y = 12 are located at: (4,0)
To find the x-intercept, you must substitute in 0 for y and solve for x.
The y-intercept of 3x + 4y = 12 are located at: (0,3)
To find the y-intercept, you must substitute in 0 for x and solve for y.
Please view the graph attached below that has the slope and intercepts of 3x + 4y = 12 sketched.
