An equiavalent expression for 40+36 can be:
46+30
50+26
etc.
As long as the expression equals 76, it is correct
hope this helps
We can subsitute since
23x+4=y and
4-2x=y
therefor
23x+4=y=4-2x
so
23x+4=4-2x
minus 4 on both sides
23x=-2x
add 2x to both sides
25x=0
divide both sides by... uh oh
I guess x=0
sub
4-2(0)=y
4-0=y
4=y
the solution is (0,4)
Answer:
15
Step-by-step explanation:
Let x represent the number of hours it takes the larger hose to fill the pool. Then each hour, it contributes 1/x of the pool volume. Similarly, the other hose contributes a volume of 1/(1.5x) each hour.
The two hoses together contribute a volume of 1/9 of the pool volume each hour:
1/x +1/(1.5x) = 1/9
2.5/(1.5x) = 1/9 . . . . combine the fractions
22.5/1.5 = x . . . . . . multiply by 9x
15 = x
It takes the larger hose 15 hours to fill the pool alone.
Volume of cone : (1/3) * pi * r^2 * h
<span>35 = (1/3) * 3.14 * 2.4^2 * h </span>
<span>h = 35 / ((1/3) * 3.14 * 2.4^2) </span>
<span>h ≈ 5.805 in </span>
<span>h = 5.81 in

The answer is A because it is -1 because it would go to the right when you add two
