Answer 1

Answer:

convert it to improper fractions first

Step-by-step explanation:

4 x 7 + 3 = 31

So, 7 3/4 = 31/4

Similarly, 5 x 2 + 2 = 12

So, 2 2/5 = 12/5

Now we have,

31/4 - 12/5

Make the denominators same....

Multiply both the denominators by each other...

4 x 5 and 5 x 4 = 20 both the denominators equal to 20.

Now multiply the numerators like that

so, 31 x 5 and 12 x 4

equals to 151/20 and 48/20

Now subtract both ...

151-48 = 103

So the answer is 103/20

Hope it helps!!!

It's the third option, y = [tex]\frac{1}{3}[/tex] x + 2

Step-by-step explanation:

It is rise over run.

This means you go up one, then go three right.

Answer:

Read below please :)

Step-by-step explanation:

when writing an equation, you use rise over run, or, [tex]\frac{rise}{run} or ( \frac{y}{x} )[/tex], so you'd get 3/1 (3) + 6/2 (3) as you can see, y = half of x. So, because you know what x(6), and what y(3) is, just imput the answers and see which makes sense.

Ratio of the ages of three children is 2:5:1. The sum of their ages is 32 years. Find the ages of the youngest and the eldest

child.

Answers

Answer:the ages of the youngest and the eldest is 4 years and 20 Years respectively

Step-by-step explanation:

Ratio of the ages of three children is 2:5:1.

Total ratio =2+5+1=8

So that

the 1st Child's age =2/8 x 32=8 years

2nd Child's age =5/8 x 32= 20 years

3rd Child's age =1/8 x 32= 4 years

Therefore the ages of the youngest and the eldest is 4 years and 20 Years respectively.

Melanie earns $97.50 in 6 hours. Earl earns $296.00 in 20 hours. Who earns the higher rate per hour? Explain your answer.

Answers

We will divide the earnings with the time needed to work to earn that money .

Melanie : 97.5 ÷6=16.25

Earl: 296 ÷20=14.8

So Melanie earns $16.25 per hour,while Earl earns $14.8 per hour

Since 16.25 >14.8,Melanie earns more per hour

(Hope this helped)

Melanie earners a higher rate per hour because 97.50/6 = 16.25
