Answer:
(a) The monthly budget for housing would range from $2,291.50-$2,749.80.
the good estimate would be $2,566.48.
(b) The monthly budget for housing would range from $1,250-$1,500.
the good estimate would be $1,400.

Answer:
1) x=4-y-z
2) x=-12+4y-4z/3
3) x=-1+y+4z/2
Step-by-step explanation:
1) Subtract y+z from both sides.
x+y+z-(y+z)=4-(y+z)
Simplify
x=4-y-z
2) Subtract -4y+4z from both sides.
-4y+4z-(-4y+4z)=12-(-4y+4z)
Simplify
-3x=12+4y-4z
Divide both sides by -3
-3x/-3=12/-3+4y/-3-4z/-3
x=-12+4y-4z/3
3) Subtract -y-4z from both sides.
2x-y-4z-(-y-4z)=-1-(-y-4z)
Simplify
2x=-1+y+4z
Divide both sides by 2
2x/2=-1/2+y/2+4z/2
Simplify
x=-1+y+4z/2
Hope this helps! Pls give brainliest!
D. P(A x B)
To work out the success of both events you have to multiply them together. I'd seriously reccomend learning this rule as it's very important later on in mathematics as it's basically the foundation of all probability statistics.
