Answer:
area = 8x^2 - 2x - 15
Step-by-step explanation:
area = length x width
area = (2x-3) x (4x+5)
area = 8x^2 + 10x - 12x - 15
reduce:
area = 8x^2 - 2x - 15
1. -6y
2. 4y+20
3. -6x+6y+4
4. 3x-44
5. •work:
•plug in 4 to the equation
5(2-4)=-10
10-20=-10
-10=-10
•so, yes it is a solution to 5(2-x)
6. •work:
4x+20=0
-20 -20
4x=-20
4x/4=-20/4
x=-5
7. •work:
5x-3=2x-27
-2x -2x
3x-3=-27
+3 +3
3x=-24
3x/3=-24/3
x=-8
8. •work:
6x-8=2x+16
-2x -2x
4x-8=16
+8 +8
4x=24
4x/4=24/4
x=6
9. •work:
12-3x=22+2x
-2x -2x
12-5x=22
-12 -12
-5x=10
-5x/-5=10/-5
x=-2
10. •work:
x+7x-12=-20
8x-12=-20
+12 +12
8x=-8
8x/8=-8/8
x=-1
11.•work:
7x+4-13x=-1+23
-6x+4=-1+23
-6x+4=22
-4 -4
-6x=18
-6x/-6=18/-6
x=3
here you go! hope this helped!! :)
To find the volume of a dome, you would have to find the volume of the sphere, theoretically, and then divide it by two. To calculate the volume, we would use the formula 4/3
![r^{3}](https://tex.z-dn.net/?f=%20r%5E%7B3%7D%20)
. The radius (r) in this case is half of the diameter which is 14. 4 x 3.14 (pi) = 12.56. 12.56 x 14 x 14 x 14 (2744) = 34464.64. If we divide this number by 3, we get 11488.2133. If we divide this by 2 (to get the dome), we get 5744.10656. Which would be 5744.1 rounded to the nearest tenth.
Answer:
Find out the how much will the bike cost after the 30% off and markdown .
To prove
As given
Original cost of the bike = $950.00
A bike was recently marked down $200.00 from its initial price.
Than
Price of bike after marked down = $950.00 - $200.00
= $750
As given
If you have a coupon for an additional 30% off after the markdown.
30% is written in the decimal form.
![= \frac{30}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B30%7D%7B100%7D)
= 0.30
Cost of the bike when coupon for an additional 30% off after the markdown iapply = 0.30 × 750
= $ 225
Than cost of the bike when coupon of 30% off and marked down of $200.00 apply = Price of bike after marked down - cost of bike when coupon for an additional 30% off after the markdown apply
= $750 - $ 225
= $ 525
Therefore the Than cost of the bike when coupon of 30% off and marked down of $200.00 apply is $ 525 .
