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

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.

Question about finding intercepts from a table. Hope someone can answer!

Answers

Basically you have to use the table to find the equation of the line, then plug in a point into x and y and the b you will get is your y-intercept.

Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:

1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)

2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.

Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)

Now that you know m, your incomplete equation will be this:
y=2x+b.

Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)

Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

Then you divide both sides
-9x = -37

01/29

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

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 :)
