Last week Macy ran 4 times as many miles as Jackson. They ran a total of 20 miles. How many miles did Macy run? how many morr mi

WITCHER [35]

Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
$j = 20 \div 4$
which would end up in the answer being 5 which is the right answer while someone else can see it as
$j = 20 - 4$
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20

Need help with this question 2 + (4h- 1) = 13h Need All Steps Plz

vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

First, we need to Simplify the equation.

2 - 1 + 4h = 13h

1 + 4h = 13h

Now, we need to Subtract 4h from both sides of the equation.

1 + 4h - 4h = 13h - 4h

1 = 9h

Finally, we Divide both sides by 9 to get h.

$\frac{1}{9} = h$

h is equal to $\frac{1}{9}$ .

To check your answer, we plug $\frac{1}{9}$ back into the given equation.

$2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1$

I hope this helps!

A grocer has 36 apples and 20 pears. The grocer arranges the fruit into groups that have the same ratio of apples to pears as th

cupoosta [38]

Answer:

Therefore no of apples in that group is 18

Step-by-step explanation:

Given:

No. of apples = 36

No. of pears = 20

Also it is given that grocer arranges the fruit into groups that have the same ratio of apples to pears as the whole collection of fruit.

first we find the ratio of apples and pears in whole collection which is given below

No. of apples/No. of pears = 36/20 = 9/5

Now its a problem of ratio

It is given that no of pear in one group is 10

Let the no of apples in that group be X

According to the question

No. of apples in whole collection/ No. of pear in whole collection = No. of apples in the group/ No. of pears in the group -------------> A

9/5 =X/10

=> X = (9*10)/5 = 18

Therefore no of apples in that group is 18.
