Answer:
He raised $25.50 over his fund raising goal
Step-by-step explanation:
Here, we want to calculate his fund raising goal.
Let his fund raising goal be $x
We are told that he raised 151% of his fundraising goal;
Thus,
mathematically;
151% of x = 75.5
151/100 * x = 75.5
151x = 100 * 75.5
151x = 7550
x = 7550/151
x = $50
So the amount he raised over his fund raising goal will be $75.50 - $50 = $25.50

Answer:
1/10 is the correct answer

3/5=6/10
7/10-6/10=1/10
Answer:
(5,2,2)
Step-by-step explanation:
-3x+4y+2z = -3
2x-4y-z=0
y = 3x-13
Multiply the second equation by 2
2*(2x-4y-z)=0*2
4x -8y -2z =0
Add this to the first equation to eliminate z
-3x+4y+2z = -3
4x -8y -2z =0
-------------------------
x -4y = -3
Take the third equation and substitute it in for y
x - 4(3x-13) = -3
Distribute the 4
x - 12x +52 = -3
Combine like terms
-11x +52 = -3
Subtract 52 from each side
-11x +52-52 = -3-52
-11x = -55
Divide by -11
-11x/-11 = -55/-11
x=5
Now we can solve for y
y =3x-13
y =3*5 -13
y = 15-13
y=2
Now we need to find z
2x-4y-z=0
2(5) -4(2) -z=0
10-8 -z=0
2-z=0
Add z to each side
2-z+z= 0+z
2=z
x=5, y=2, z=2
