For every 14 dollars you can get 5 kg. $14/5kg
You want to find one kg so divide by 5 on both sides
So...
$2.80/kg
Hope this helps and have a nice day!
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
Answer:
y = mnp/(m + n)
Step-by-step explanation:
I assume that both capital y and small case y are meant to be the same variable. If not, let me know, and I'll solve it again for small case y.
y/m + y/n = p
Factor y out on the left side.
y(1/m + 1/n) = p
y = p/(1/m + 1/n)
Multiply the right side by (mn)/(mn).
y = pmn/[(1/m + 1/n)mn]
y = pmn/(n + m)
y = mnp/(m + n)
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
