Find three consecutive even integers such that six times the sum of the first and the third is twenty - four greater than eleven

dedylja [7]

Answer:

1st = 22

2nd = 24

3rd = 26

Step-by-step explanation:

1st = x

2nd = x +2

3rd = x + 4

6(x + x + 4) = 24 + 11(x + 2)

6(2x + 4) = 24 + 11x + 22

12x + 24 = 46 + 11x

x + 24 = 46

x = 22

x + 2 = 24

x + 4 = 26

Hey please help with this question( no links!!)

So the area of a circle is pi times the radius squared.
A= pi*r^2
The radius here is the diameter divided by 2.
radius = 16/2
r = 8
A= 3.14*(8)^2
A= 3.14*64
A= 200.96

C. 200.96 in^2

Lily's car has a fuel efficiency of 8liters per 100 kilometers. What is the fuel efficiency of Lily's car in kilometers per lite

Ne4ueva [31]

Using Algebra I have concluded that the answer is 12.5 kilometers per liter. :D

First set up your equation

$\frac{8}{100} = \frac{1}{x} \\\\Next multiply by x (\frac{8}{100})x = (\frac{1}{x})x \\\\$

$(\frac{8x}{100}) = 1\\\\$

Then multiply by 100

$(\frac{8x}{100}) 100 = (1) 100$

$8x = 100\\\\Finally divide by 8\frac{8x}{8} = \frac{100}{8}$

$x = 12.5$

Hope this helps!
