Answer:
3/100 times 3 is 0.09 or 9/100
x intercept is calculated by putting y = 0 in equation which gives us x = 3.
so option 4
Because ratios can be written as fractions
![\frac{mulch}{2.25}=\frac{gravel}{1.33}](https://tex.z-dn.net/?f=%5Cfrac%7Bmulch%7D%7B2.25%7D%3D%5Cfrac%7Bgravel%7D%7B1.33%7D)
172 =
![\frac{mulch}{2.25}+ \frac{gravel}{1.33}](https://tex.z-dn.net/?f=%5Cfrac%7Bmulch%7D%7B2.25%7D%2B%20%5Cfrac%7Bgravel%7D%7B1.33%7D)
172 -
![\frac{mulch}{2.25}](https://tex.z-dn.net/?f=%5Cfrac%7Bmulch%7D%7B2.25%7D)
=
![\frac{gravel}{1.33}](https://tex.z-dn.net/?f=%5Cfrac%7Bgravel%7D%7B1.33%7D)
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56
(Y) Number of buckets given away
(X) Number of gallons donated
Y = X/5 is the equation
If X = 30000 and y= X/5, then Y=30000/5=6000 buckets donated
Using Distributive Property:
Combine and get all the terms in left sides and set it equal to zero and solve for m.
(m-5) (m-1) = -3 //Basic step of distribution.
m(m-1) -5(m-1) = -3
m^2 - m - 5m + 5 = -3 //Combine like terms and add 3 on both sides.
m^2 - 6m + 8 = 0 //Factor
m^2 - 4m - 2m + 8 = 0
m(m-4) -2(m -4) = 0
(m-4)(m-2) = 0 //Solve for m.
Got two equations:
1)m - 4 = 0
m = 4
2) m - 2 = 0
m = 2
Solution: m = 4, 2
//Hope this helps
