Answer:159
Step-by-step explanation:
ur welcome
Since you have y alone on one side of the equation......
Use substitution and plug in 1/2x-4 for y in the other equation.
Distribute
Combine like terms
Add 8 to both sides
Divide by 4
and 
Plug this value in for x
Simplify
Multiply everything by 8 and simplify
Divide.....
Your answers are:
You must use distributive property to get 2m+10+48m+8 and then add all like terms. You get 50m+18 as your final answer.
Answer: To find the finance charge you multiply the balance times 0.23 / 12 .
To find the interest charge to an account, you have to multiply the balance by the percent rate (APR).
The problem in this case is that interest is charged monthly, but the rate is yearly.
To fix this problem, just divide the rate by 12.
0.23 / 12
x^2+6x-5=0
x^2=2x
2x+6x-5=0
2x+6x=8x
8x-5=0
+5 +5
(if you don’t know what I’m doing here is that I’m removing the negative 5 by putting a positive 5 since both of them make 0. Also the “x” always stay alone and the unit stays as the unit)
(I putted the positive under the 0 because what u do to the unit you need to do the same thing with the other.)
8x/8=5/8
(If ur lost here it means dividing.)
The answer
X=0.625
(btw I’m not really sure if this is right so um don’t really trust me in this lol)
