Answer:
a = 3.2
Step-by-step explanation:
2( -a - 8) + 7a = 0
-2a -16 + 7a = 0
5a - 16 = 0
5a = 16
a = 16/5
a = 3.2
The answer is (6g-5h)(8g+3h)
Answer:
x=2
Step-by-step explanation:
First of all cross-multiply.
1/2x=1/4
(1) x (4) =1 x 2x
4=2x
After flip the equation.
2x=4
Then divide both sides by 2.
2x/2=4/2
x=2
(1,10) satisfy the first equation and the second equation.
Since the x-coordinate is 1 and the y-coordinate is 10, you can plug these numbers in for the x and y of the equation like this:
10 = 1 + 9
10 = 10
This satisfy the first equation of y = x + 9
10 = 9(1) + 1
10 = 10
This satisfy both of the equations, so this is a solution to this system of equations.
LOL! I was in eighth grade last year, I understand the struggle! ._.
