120 people. 50% is 60 people. 20% is 24 people, the rest is 36.
Let L=large donation, M=medium. We also have L=4M. The donation equation is then:
60L+36M+24=4440
60L+36M=4416 substitute L=4M
276M=4416
M=4416/276=16
So the answer is $16
Step-by-step explanation:
Pythagorean Formula = a2 + b2 = C
which is a = Side of triangle
b = Side of Triangle
c = Hypotenuse
Answer:
B. No solution
Step-by-step explanation:
y = 3x+9
y = 3x-7
Set the two equations equal since they are both equal to y
3x+9 = 3x-7
Subtract 3x from each side
3x+9-3x = 3x-7-3x
9 = -7
This is never true, so there are no solutions
Answer:
y = 8x + 25
Step-by-step explanation:
Using the coordinates (10, 105) and (20, 185)
The standard linear equation is expressed as y = mx+c
m is the slope
c is the intercept
m = 185 - 105/20-10
m = 80/10
m = 8
Get the y-intercept
Since y = mx+c
105 = 8(10) + c
105 = 80 + c
c = 105 - 80
c = 25
Get the required equation
Recall that y = mx+c
y = 8x + 25
Hence the required equation is y = 8x + 25
Is is the first one. 1600=.45x
