Answer:you would tell them that you would divide $15.00 by 3 to get you’re answer.
(1 * 10) ^ 15 * (1 * 10) ^ 15
10^15 * 10^ 15
X^m * X^n = X^m +n
10^15 * 10^15 = 10^ 15+15 = 10^30 or (1 x 10) ^30.
Answer:
no
22.25 minutes
Step-by-step explanation:
First determine how long it will take her to read the entire book
20 pages 47 pages
-------------- = ----------------
35 minutes x minutes
Using cross products
20x = 35*47
20x=1645
Divide by 20
20x/20 = 1645/20
x =82.25 minutes
This is more than 1 hour ( 1 hour = 60 minutes)
82.25 minutes - 60 minutes = 22.25 minutes
She will need 22.25 more minutes
We have that
<span>If (5x-4+13x=5) --------------> then x=1/2
Step 1
</span>let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then
5=5-----------> <span>the value of x = (1/2) satisfies equality</span>
Answer:
10.8 yards
Step-by-step explanation:
Since she has 19.7 yards left over, the amount she used for curtains is ...
84.5 - 19.7 = 64.8 . . . . yards
Then each of the 6 identical curtains used 1/6 of this amount, or ...
(64.8 yards)/6 = 10.8 yards
_____
You can write an equation if you like. Let c represent the yardage used for each curtain. Then the total number of yards of fabric Jennifer has is ...
6c +19.7 = 84.5
We can find the value of c by subtracting 19.7, then dividing by 6 (as above).
6c = 64.8 . . . . subtract 19.7
c = 10.8 . . . . . divide by 6
Jennifer used 10.8 yards of fabric per curtain.
