G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
20%of £800 is 800÷5 =160
800 + 160 =960
Answer:
Option C that is
the right choice.
Step-by-step explanation:
Given,
A rectangle with the measures of its diagonal DF and EG.
Measure of diagonal DF = ![5x-5](https://tex.z-dn.net/?f=5x-5)
Measure of diagonal EG = ![x+11](https://tex.z-dn.net/?f=x%2B11)
Note:Diagonal length of the rectangle are same.
So DF = EG
![5x-5=x-11](https://tex.z-dn.net/?f=5x-5%3Dx-11)
Subtracting
and adding
on both sides.
We have,
![5x-x=11+5](https://tex.z-dn.net/?f=5x-x%3D11%2B5)
![4x=16](https://tex.z-dn.net/?f=4x%3D16)
Dividing 4 both sides.
![x=\frac{16}{4}=4](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B16%7D%7B4%7D%3D4)
So the value of
is
.
Now plugging the value of
,we will find the numeric value of DF and EG.
DF = ![5x-5 =5(4)-5=15](https://tex.z-dn.net/?f=5x-5%20%3D5%284%29-5%3D15)
EG= ![x+11=4+11=15](https://tex.z-dn.net/?f=x%2B11%3D4%2B11%3D15)
Both are equal DF = EG.
So x=
and the length of diagonals are equal, DF = EG =
unit.
