Leon has a handful of of dimes and quarters valuing $3.40. He has 6 more dimes than he does quarters. How many of each coins doe

lesya [120]

Answer: 14 dimes and 8 quarters

Step-by-step explanation:

dimes ($0.10): x + 6

quarters ($0.25): x

Cost*quantity of dimes + Cost*quantity of quarters = Total value

0.10(x + 6) + x(0.25) = 3.40

0.10x + 0.60 + 0.25x = 3.40

0.35x + 0.60 = 3.40

-0.60 -0.60

0.35x = 2.80

÷0.35 ÷0.35

x = 8

dimes: x + 6 = 8 + 6 = 14

Josephine can correct her students' test papers in 9 hours, but if her teacher's assistant helps, it would take them 7 hours. Ho

kirill [66]

Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given as follows:

Josephine: 1/9.

Assistant: 1/x.

Together: 1/7.

Hence:

$\frac{1}{9} + \frac{1}{x} = \frac{1}{7}$

$\frac{x + 9}{9x} = \frac{1}{7}$

$9x = 7x + 63$

2x = 63

x = 31.5.

It would take the assistant 31 hours and 30 minutes to do it alone.

7nadin3 [17]

Answer: 270.9 miles.

Step-by-step explanation:

The formula we use here is :

$\text{Distance=Speed * Number of gallons of gasoline}$

Given : Ashton used 12.6 gallons of gasoline to drive his car on a weekend trip. he averaged 21.5 miles per gallon.
