Create a proportion.
Since it takes 7 minutes to print 63 pages, and half an hour is 30 minutes, you create two ratios(unit per unit) and line up the units(minutes to minutes, pages to pages).
Now you cross multiply, 63 * 30 = 1890 and 7 * x = 7x.
So we have 1890 = 7x.
Then we divide both sides by seven.
270 = x, therefore you can print 270 pages in half an hour :)
First take note that Mr. Day gave them $24 to share and Mrs. Day gave each of them $2. There were also four girls in total.
So we'll divide 24 by 4 resulting each girl getting $6 each from Mr. Day.
Now we'll add the $2 Mrs. Day gave them resulting in the answer.
Each girl made $8 from Mr. and Mrs. Day
Answer:
Step-by-step explanation:
You start off by rewriting the equation:
Then you have to factor:
Then you subtract the 0.2x:
Add the positives on the right:
Add 14:
Divide:
You get x is approximately equal to 10.84
The general formula: y=mx+b
(6,2) ⇒ x=6,y=2
m=3
b=?
2=3*6+b
2=18+b
b=-16
<u>y=3m-16</u>
Answer:
68
Step-by-step explanation:
F = 1.8(20)+32 = 68
