$7\frac{4}{5} = \frac{28}{5}$

because 7 x 4 = 28

$4\frac{7}{5} = \frac{28}{5}$

because 4 x 7 = 28

This means that

$7\frac{4}{5} = [tex]4\frac{7}{5}$

$6\frac{12}{5} = \frac{72}{5}$

because 6 x 12 = 72

This means

$7\frac{4}{5} = [tex]6\frac{12}{5}$

<h2>And h is false.</h2>

Max makes bread that calls for 7/8 cup of raisins per loaf. He has 5 1/4 cups of raisins. How many loaves of bread can he make?

Sveta_85 [38]

Answer:

False.

Step-by-step explanation:

The answer is NOT 6 1/2 loaves it is 6 loaves.

Knowing that there Max has 5 1/4 cups of raisins and each loaf requires 7/8 cup of raisins, we would need to divide.

Let's turn the 5 1/4 into an improper fraction so when we divide the two fractions, it would be easier!

<u>To turn 5 1/4 into an improper fraction we need to...</u>

5 x 4 = 20

20 + 1

21/4

Now we divided 21/4 by 7/8.

When dividing fractions remember the rule: KEEP CHANGE FLIP!

We keep the first fraction...which is 21/4 in this case

Change the sign from division to multiplication

21/4 x 7/8

And flip 7/8 so it becomes 8/7

21/4 x 8/7

= 168/28

= 6 loaves

So, the answer is not 6 1/2 loaves (false!)

Can someone please help me with math.

Oxana [17]

Answer:

Step-by-step explanation:

Hello There!

First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)

Because the fee is 3 dollars we can immediately eliminate answers B and C

Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)

Once again we want to choose two points on the line and plug it in into the slope formula

the points are optional but i have chosen the points (1,4.5) and (2,6)

*plug it into the slope formula*

$slope=\frac{6-4.5}{2-1} \\6-4.5=1.5\\2-1=1\\slope =\frac{1.5}{1} or1.5$

so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A

there were some people on a train. 19 people get off the train at first stop.17 people get on the train.now there are 63 people

sdas [7]

Let the people initially on the train be 'x'.

19 people got off the train --> x - 19

17 people got on the train --> x - 19 + 17

Remaining people on the train = 63

Therefore, x - 19 + 17 = 63
                  x - 2 = 63
                       x = 63 + 2
                       x = 65

Verification:
65 - 19 + 17 = 63
65 - 2 = 63
63 = 63
