Answer:
49/54
Step-by-step explanation:
Let x = the first number
y = the second number
-------------------------------------
First: set up the equations.
Four times a first number: 4x
Decreased by a second number: - y
Is 4: = 4
4x - y = 4.
The first number increased by: x +
three times the second number: 3y
is -25: = -25
x + 3y = -25.
------------------------
You can make your system of equations now.
4x - y = 4
x + 3y = -25
I would use substitution to solve these.
To do substitution, isolate a variable first, in one of the equations. I would probably isolate x in the second equation.
x + 3y = -25
x = -25 - 3y
Now, you can substitute -25 - 3y into 4x - y = 4, as x.
4x - y = 4
4(-25 - 3y) - y = 4
Now just solve for y.
-100 - 12y - y = 4
-13y = 104
y = -8
Now, you can put -8 as y into one of the original equations, I'll just use 4x - y = 4.
4x - y = 4
4x - (-8) = 4
4x + 8 = 4
4x = -4
x = -1
So the first number is -1, and the second -2.
It would be: 5(6h - 1) - 5h
= 30h - 5 - 5h
= 25h - 5
In short, Your Answer would be Option C
Hope this helps!
Each 0 is a point in the right direction like 2.2x10^4 would be 22,000 because you are moving the 2.2 4 place right of the decimal point.
