Px + qy = r
2px - qy = 2r
----------------add
3px = 3r
x = 3r/3p
x = r/p
252 divided by 9 is 28
Firstly, I muplity 20 and 9.
I have 180.
Then I also muplity 8 and 9.
I got 72.
Then I add 72 and 180 which got me 252.
(I hope this helped!)
Answer:Lateral surface area is 847.8 centimeters^2
Step-by-step explanation:
The formula for determining the lateral surface area of a cylinder is expressed as
Lateral surface area = 2πrh
Where
r = radius of the cylinder
h = the height of the cylinder
From the information given,
r = 9 centimeters
h = 15 centimeters
π = 3.14
Lateral surface area = 2 × 3.14 × 9 × 15 = 847.8 centimeters^2
Let the letter o represent the original price.
17.85 = o + (o*1.10)
17.85 = 2.10 * o
o = 17.85/2.10=8.5
The original price was $8.50
<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)
</span><span>zero-product property
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
x = -5/4
x = -1.25
x - 5 =0
x = 5
answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25
