Answer:
1.06
Step-by-step explanation:
An equation can be set up as: 45,750 = 50x + 800
x representing each installment
We can simplify this by subtracting 800 and dividing by 50:
44,950 = 50x
899 = x
I’m not sure whether there is a typo in the function but I might have the answer.
If f(x) = 5(x+1)+3 = -12 then you can solve for x.
5(x+1)+3 = -12
5x + 5 + 3 = -12 << expand the brackets
5x + 5 = - 15 << minus 3
x + 1 = -3 << divide everything by 5
x = -4 << minus 1
I don’t know if this helps x Sorry
Answer:
x²+2x+3
Step-by-step explanation:
We are to simplify the expression;
5x³+10x²+15x/5x
Factor out 5x from the numerator
= 5x(x²+2x+3)/5x
5x will cancel out both at the top and bottom to have;
x²+2x+3
Factorize
x²+2x+3
Hence the simplified form is x²+2x+3
So you use 40 gallons of water *PER* day.
Average water use in Dec?
(hint: in math * means multiplication)
Dec. has 31 days
so
40 * 31
1240
Average water use is 1240 gallons
Hope this helps :)
