What value is true of x makes this equation true 0.7x-5=0.2x+1

Sever21 [200]

Answer:

x=12

Step-by-step explanation:

First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.

What is the volume of the rectangular prism below in cubic inches?

lions [1.4K]

Answer:

24

Step-by-step explanation:

The volume formula is all the dimensions multiplied together, or lengthxwidthxheight.

So, you do 1x1x2 which is 2 feet. HOWEVER, it is looking for CUBIC INCHES, not cubic FEET.

There are twelve inches in a foot so 2x12=24 inches.

You and your friend share a paper route. You can deliver 4 papers in one minute and your friend can deliver 3 papers in one minu

nadezda [96]

Answer:

$n\times \frac{1}{4}+(75-n)\times \frac{1}{3}$

Step-by-step explanation:

Given that:

4 papers are delivered by first person in one minute.

Rate of delivering one paper

or

Time taken to deliver one paper can be calculated by the formula:

$\dfrac{\text{Total Time taken}}{\text{Number of papers delivered}}$

Time taken to deliver one paper by first person = $\frac{1}{4}$

3 papers are delivered by second person in one minute.

Time taken to deliver one paper by second person = $\frac{1}{3}$

Total number of papers = 75

Number of papers delivered by first person = $n$

So, number of papers delivered by second person = ( $75-n$ )

Time taken to deliver $n$ newspapers = Number of newspapers delivered <em>multiplied by </em>Time taken to deliver one newspaper

Time taken by first person = $n\times \frac{1}{4}$

Time taken by second person = $(75-n)\times \frac{1}{3}$

So, Total time taken can be written as:

$n\times \frac{1}{4}+(75-n)\times \frac{1}{3}$
