T = (3m - n)/5
5 * T = (3m - n)/5 * 5
5T = 3m - n
n + 5T = 3m - n + n
n + 5T = 3m
(n + 5T)/3 = (3m)/3
(n + 5T)/3 = m
Answer: m = (n+5T)/3
Hope that helped =)
Is it equal to 50% because 2/4 is .5 and to make a fraction you move the decimal over two places to the right<span />
Answer:
2x - y = -7
Step-by-step explanation:
The equation y = 2x+7 needs to be written in standard form where A must be positive.
To convert to standard form, subtract 2x from both sides.
-2x + y = 7
Multiply each term by -1.
-1(-2x + y =7)
2x - y = -7
Answer:
-7x(x + 4)
Step-by-step explanation:
Not sure exactly what you're doing with this, but I know you're not solving it for x because there's no " = " there so I am assuming you're simplifying it as much as possible. I'm going with that.
First thing is to distribute through the parenthesis by multiplying 4x by 3x and then 4x by -7 to get:
Now combine like terms to get
The last thing you could do now is pull out what's common between each of those terms which is -7x. When you do that, you're left with
-7x(x + 4)
