Answer:

173 inches

Step-by-step explanation:

i don't entirely understand the question but i think you're trying to add 3 feet 6 inches + 8 feet 2 inches + 4 inches + 2 feet 5 inches?

<u>(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)</u>

<em>i've added these parentheses in order to make it easier to see the grouped measurements. this isn't necessary but i'm just doing it to hopefully aid my explanation since there's so many terms in the expression!</em>

<em />

start by converting everything to inches just to make the addition as well as showing your work easier. all you have to do is multiply the amount of feet by 12 because there are 12 inches in a foot! :)

<u>(3 feet 6 inches)</u><u> + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)</u>

for your first measurement, <u>3 feet 6 inches</u>, convert 3 feet to inches by multiplying the amount of feet, 3, by 12.

3(12) = 36<em> (therefore 3 feet is equal to 36 inches!)</em>

and add the remaining 6 inches.

36 + 6 = 42 <em>(therefore 3 feet 6 inches is equal to 42 inches!)</em>

<em />

<u>(3 feet 6 inches) + </u><u>(8 feet 2 inches)</u><u> + (4 inches) + (2 feet 5 inches)</u>

for your second measurement, <u>8 feet 2 inches</u>, convert 8 feet to inches by multiplying the amount of feet, 8, by 12.

8(12) = 96 <em>(therefore 8 feet is equal to 96 inches!)</em>

and add the remaining 2 inches.

96 + 2 = 98 <em>(therefore 8 feet 2 inches is equal to 98 inches!)</em>

<u>(3 feet 6 inches) + (8 feet 2 inches) + </u><u>(4 inches)</u><u> + (2 feet 5 inches)</u>

nothing needs to be done to this quantity since it's already in inches.

<u>(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + </u><u>(2 feet 5 inches)</u>

for your fourth measurement, <u>2 feet 5 inches</u>, convert 2 feet to inches by multiplying the amount of feet, 2, by 12.

2(12) = 24 <em>(therefore 2 feet is equal to 24 inches!)</em>

and add the remaining 5 inches.

24 + 5 = 29 <em>(therefore 2 feet 5 inches is equal to 29 inches!)</em>

now, here is the expression with everything in inches.

<u>42 inches + 98 inches + 4 inches + 29 inches</u> <em>aka</em> <u>42 + 98 + 4 + 29</u>

<u />

now add everything up!

42 + 98 + 4 + 29 = 173 inches

your total is 173 inches! i hope this helps and i hope i explained it well enough. have a lovely day! <3

The cost of a book was decreased from 60 to 50 by what percent the price decrased with solution​
Artist 52 [7]

Answer:

The price decreased by 16 1/3%, or approximately 16.3%

Step-by-step explanation:

Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.

percent change = (new price - old price)/(old price) * 100%

In this case, use:

new price = 50

old price = 60

percent change = (new price - old price)/(old price) * 100%

percent change = (50 - 60)/60 * 100%

percent change = -10/60 * 100%

percent change = -1/6 * 100%

percent change = -100/6% = -50/3% = -16 1/3%

The price decreased by 16 1/3%, or approximately 16.3%

Solve this problem please <br> x/3+6-2x=-6
Nikolay [14]

Answer:

36/5

Step-by-step explanation:

x/3 + 6 -2x = -6

multiply the whole equation by 3 to get rid of the denominator of the first x term.

x+18-6x = -18

move x terms to one side and numerical terms to the other, subtract 18 from both sides in this case

x+18-6x-18=-18-18

x-6x = -36

simplify

-5x = -36

divide both sides by -5 to isolate x

x = -36/-5

=36/5
