Cost per ounce means you take the cost and divide it by the cost:
<span>3.36 / (21/2) </span>
<span>division of fractions changes to the multiplication of the reciprocal: </span>
<span>3.36 * (2 / 21) </span>
<span>3.36 and has 21 as a factor, so let's cancel it: </span>
<span>0.16 * 2 </span>
<span>$0.32 per ounce</span>
BD = BC + CD
7x - 10 = (4x - 29) + (5x - 9)
7x - 10 = 9x - 38
2x = 28
Ans: x = 14
BC = 4x - 29
= 4(14) - 29
= 27
Ans: BC = 27
CD = 5x - 9
= 5(14) - 9
= 61
Ans: CD = 61
BD = 61 + 27
= 88
Ans: BD = 88
Hi there! :)
<u>Answer:</u>
Donovan babysat for 7 hours on Saturday in order to earn $31.50.
Step-by-step explanation:
In order for you to answer your question, you'll need to use the cross product method:
$9 → 2 hours
$31.50 → X hours
<u>(2 × 31.50)</u> ÷ 9 = X hours
<u>63 ÷ 9</u> = X hours
<u>7 = X hours</u>
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
There are 18 seniors and 25 juniors.
Step-by-step explanation:
- Find your equation. For this equation, it comes out to be:
x + x + 7= 43 or 2x+7=43
X represents the amount of seniors.
The amount of juniors can be represented as x+7
- Solve the equation. It comes out to be:
1st - Transfer the 7 to the other side to get the x by itself
2x=36
2nd - Divide 36 by 2 to leave x by itself
x=18
- Answer the question. Because you didn't specify what your were asking for, I imagine it's the number of player from each class.
Because x represents the seniors, there are 18 seniors.
There are 7 more juniors, add 7 to 18, so there's 25.
