80 = 10r
you need to isolate the variable, so divide both sides by ten.

you get

NEED HELP ASAPPP!!! Drag each scenario to show whether the final result will be greater than the original
Lemur [1.5K]

Answer:

Greater than the original = 2, 4

Less than the original = 5

Same as the original = 1, 3

Step-by-step explanation:

Let the original value be x.

1. A $30 increase followed by a $30 decrease.

New value =x+30-30=x, it is same as original value.

2. A 20% decrease followed by a 40% increase.

Afer 20% decrease.

New value =x-\dfrac{20}{100}x=x-0.2x=0.8x

Afer 40% increase.

New value =0.8x+\dfrac{40}{100}(0.8x)=0.8x+0.32x=1.12x, it is greater than original value.

Similarly check the other values.

3. A 100% increase followed by a 50% decrease.

New value =x+\dfrac{100}{100}x-\dfrac{50}{100}(x+x)=x, it is same as original value.

4. A 75% increase followed by a 33% decrease

New value =x+\dfrac{75}{100}x-\dfrac{33}{100}(x+0.75x)=1.1725x, it is greater than the original value.

5. 55% decrease followed by a 25% increase

New value =x-\dfrac{55}{100}x+\dfrac{25}{100}(x-0.55x)=0.5625x, it is less than the original value.

Therefore, Greater than the original = 2, 4, Less than the original = 5, Same as the original = 1, 3 .

Day Drive 270 miles and 6 hours how many miles do you drive in 13 hours ​
NikAS [45]

Answer:

The answer is

<h2>585 miles</h2>

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

Day Drive 270 miles in 6 hours

So in order to find the distance drove in 13 hours, we compare the distance drove in 6 hours to the distance drove in 13 hours and solve

That's

if in 6 hours Day drove 270 miles

Then in 13 hours the person will drive

\frac{13  \times 270}{6}  =  \frac{3510}{6}

We have the final answer as

<h3>585 miles</h3>

Hope this helps you
