Answer:
or 6
gallons of gas.
Step-by-step explanation:
First, you have to convert both of your mixed numbers into a improper fractions.
2
= 9/4
4
= 26/6
Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.
Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM. Multiply both the nominator and the denominator by that number.
<em>4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.</em>
<em />
Repeat that for the second fraction's denominator.
<em>6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12. </em>
<em />
Then add both fractions together.
![=\frac{79}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B79%7D%7B12%7D)
If you need to, simplify.
![\frac{79}{12} = 6\frac{7}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B79%7D%7B12%7D%20%3D%206%5Cfrac%7B7%7D%7B12%7D)
Hope that helped!
Minus 6 both sides
7x²-x-6=0
hmm
using ac method we get
7x²-7x+6x-6=0
group
(7x²-7x)+(6x-6)=0
7x(x-1)+6(x-1)=0
undistribute
(7x+6)(x-1)=0
set to zero
7x+6=0
7x=-6
x=-6/7
x-1=0
x=1
x=-6/7 or 1
Answer:
x = 1 and y = -4
Step-by-step explanation:
It is given that,
-2x = 2 + y
-2x - y = 2 ---(1)
-6x - y = -2 ----(2)
<u>To find the solution of equations</u>
Step 1: Subtract eq(2) from eq(1)
-2x - y = 2 ---(1)
<u>-6x - y = -2 </u> ----(2)
4x + 0 = 4
x = 4/4 = 1
Step 2: Substitute the value of x in eq (1)
-2x - y = 2 ---(1)
-2*1 - y = 2
-2 - y = 2
y = -2 - 2 = -4
Therefore x = 1 and y = -4

Percent proportion is just any positive fraction, which, as it was mentioned, can exceed whether the percentage has a fixed denominator, equal to 100. So, although there's no intuitive difference, there is a slight distinction in the mathematical sense. It is also the amount of items in a mixture. Example: two eggs for every two cups of flour.
percent equation is a part of something equals to percent times the whole
part = percent x whole
Example: what is 80% of 20?
n = 80/100 x 20
n= 0.80 x 20
n = 16
So 16 is 80% of 20
part (16) = percent (80%) x whole (20)
n = p x w (variable representation
