1*60/40=1.5 pages per min

1.5*60=90

**B - 90**

1.5*60=90

First you can turn the fractions into improper fractions.

5 3/4 = 23/4 6 3/4= 27/4

Add numerators, denominators stay the same.

23 + 27= 50

50/4

You can either leave it or simplify

Simplified:

50/4 = 12 1/2

QUESTION POSTED AT 06/12/2019 - 12:51 PM

So,

We have three placeholders.

x, y, and z will represent the number of cookie boxes they sold for the first, second, and third weeks, respectively.

"The girls sold 5 more boxes the second week than they did the first."

x + 5 = y

"They doubled the sales of the second week for the third week."

z = 2y

"To sell a total of 431 boxes of cookies"

x + y + z = 431

Now we have our three equations.

x + 5 = y

z = 2y

x + y + z = 431

Obviously, we can substitute y and z in the last equation, because the other two open sentences tell us what they are.

x + (x + 5) + 2(x + 5) = 431

x + x + 5 + 2(x + 5) = 431

Collect Like Terms.

2x + 5 + 2(x + 5) = 431

Distribute.

2x + 5 + 2x + 10 = 431

Collect Like Terms.

4x + 15 = 431

Subtract 15 from both sides.

4x = 416

Divide both sides by 4.

x = 104

Now we can use the other two original sentences to figure out what y and z are.

x + 5 = y

104 + 5 = y

109 = y

z = 2y

z = 2(109)

z = 218

Now, to check, add x, y, and z.

x + y + z = 431

104 + 109 + 218 = 431

213 + 218 = 431

431 = 431 This checks.

The Girl Scouts sold 104 cookie boxes on the first week, 109 boxes on the second week, and 218 boxes on the third week.

We have three placeholders.

x, y, and z will represent the number of cookie boxes they sold for the first, second, and third weeks, respectively.

"The girls sold 5 more boxes the second week than they did the first."

x + 5 = y

"They doubled the sales of the second week for the third week."

z = 2y

"To sell a total of 431 boxes of cookies"

x + y + z = 431

x + 5 = y

z = 2y

x + y + z = 431

Obviously, we can substitute y and z in the last equation, because the other two open sentences tell us what they are.

x + (x + 5) + 2(x + 5) = 431

x + x + 5 + 2(x + 5) = 431

2x + 5 + 2(x + 5) = 431

Distribute.

2x + 5 + 2x + 10 = 431

Collect Like Terms.

4x + 15 = 431

Subtract 15 from both sides.

4x = 416

Divide both sides by 4.

x = 104

Now we can use the other two original sentences to figure out what y and z are.

x + 5 = y

104 + 5 = y

109 = y

z = 2y

z = 2(109)

z = 218

Now, to check, add x, y, and z.

x + y + z = 431

104 + 109 + 218 = 431

213 + 218 = 431

431 = 431 This checks.

The Girl Scouts sold 104 cookie boxes on the first week, 109 boxes on the second week, and 218 boxes on the third week.

The values given is not sufficient.

However, the rates could 18/2n or 90/10n

In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.

**Answer:**

44.44 miles per hour.

**Step-by-step explanation:**

A truck driver drove 300 miles in hours.

We have to calculate the speed per hour.

First we convert hours to decimal form.

= 6.75 hours

∵ in 6.75 hours the driver drove = 300 miles

∴ in 1 hour he drove = miles

= 44.44 miles

**The truck driver drove 44.44 miles per hour.**
