Answer:
Step-by-step explanation:
5x - 8x - 22 = 14
-3x - 22 = 14
-3x = 36
x = -12
20% off means that now it costs 80% of original price
80% = 0.8
costs 80% of (means here times (*))original price
29.99*0.8≈23.99
10% off means that now it costs 90% of original price
90%=0.9
costs 90% of (means here times (*))original price
26*0.9=23.40
23.99>23.40,
so is
<span> 10% off the original price of $26 is cheaper</span>
Answer:
B/ x=4
Step-by-step explanation:
Just take 2x to another side to be neg-, the same thing with 4 , then divide it both sides by 4 to get the answer.
The length of the actual car is 240 inches
1/25 = 9.6/x
25x9.6/1=240
x=240 inches
Hope this helped you! :D
Answer:
390=W 195=L Area=76050
Step-by-step explanation:
You have two lengths and one width for your perimeter
P= 2L + W
you are given your perimiter 780
780= 2L + W
To solve for your maximum Width
780-2L=w
Area is L * W
A= (780-2L)*L
A= 780L - 2L^2
the derivitive of the Area
A' = 780-4L =0
add 4L to both sides
780=4L
divide by 4 on both sides
195=L
Bring back 780-2L=W and plug in what you now know is L
780-2(195)=W
780-390=W
390=W
