Hope this helps! :)

1/2

5/8-1/8=4/8, we know this because when subtracting fractions with the same denominator, you keep the denominators the same and subtract the numerators. 5-1=4. this gives you 4/8. now, we know 4 is half of 8, so this is equal to 1/2, but we also can divide both 4 and 8 by 4, giving us 1/2.

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.

________________________________________________
Kenzie has $7.25. What is the maximum number of scrunchies she can buy?
______________________________

Answers

Answer:

48

Step-by-step explanation:

20 scrunchies=3 dollars

7.25 dollars = ?

1 dollar=6.66666666

0.25 dollar=1.666666666666

7*6.66666666=46.666666

:)

Answer:

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

I hope that helped :)

1/7 of ___ is 1/35
help me plz :)

Answers

Answer:1/5

Explanation: 1/35 divided by 1/7= 1/5. 1/7 of/x 1/5= 1/35.

The value of unknown number would be equal to  1/5

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the unknown number.

A negative divided by a negative is positive, then;

1/7 of x  is 1/35

1/35 divided by 1/7

1/7 of x 1/5 = 1/35.

x = 1/5

Therefore, The value is x = 1/5

Does the equation have one solution, no solutions, or all solutions? 7x + 4 = 9(x-1)

Answers

One solution
Explanation:
First you remove the parenthesis
28=9x-9
Then you calculate
-9x = -9 - 28
Then you divide both sides
-9x = -37
Solution: 37/9
Alternative form:
4 1/9 or 4.1
Note: these are all the same solutions, they are just in different forms

he closing amount of the Dow Jones Industrial Average on the stock market for four days is shown in the table below.

Date
Closing amount (in points)
01/27
13,895.98
01/28
13,881.93
01/29
13,954.4
01/30
13,860.42

Which best represents the greatest amount of change that took place from one day to the next day over the four-day period?
a loss of 93.98 points
a loss of 72.47 points
a gain of 72.47 points
a gain of 93.98 points

Answers

Answer:

C) a gain of 72.47 points

Step-by-step explanation:

because on 1/28 it has 13,881.93 and the next day 1/29 it has 13,954.4

subtract 13,954.4 - 13,881.93= 72.47

72.47 is the greatest amount change

And it can’t be 93.98 because in the instructions it said one day to the next not 2 day’s in advance
