Answer:
x = 30 I'm sure hope this helps
This one you can't really make a formula for or anything, but it's fairly simple to figure out, with a bit of guess and check.
14 is really close to 15, but that's bigger, so let's try a smaller number that would work.
It has to be divisible by 2, because you've got a whole number that is 3 1/2 times the other number. (1/2 of a whole number means it's divisible by 2).
10 is divisible by 2,
10 ÷ 2 = 5
But, 10 x 3 = 30 which is much bigger than 14.
So, we've got to start with a smaller number.
Let's try something really small, like 4. We could try 2, but 2 x 3 = 6, which, even with 1/2 of 2, isn't nearly close to 14.
Now, 4 x 3 = 12
That's quite close to 14.
And 1/2 of 4 is 2.
All we do now is add 12 to 2 and see if it works.
12 + 2 = 14
14 = 14
This one works.
That means that Gina volunteered for 4 hours, because 3 1/2 x 4 = 14.
FALSE
only 1 times 11 makes 11
if you add it that makes 12

Answer:
k=-5 or k= -13
Step-by-step explanation:
lk+9l=4
k+9=4 or k+9=-4
k=-5 or k= -13
To find
, you can switch the "x" and "f(x) or y" in the equation.
![y = \sqrt[3]{x-2}+ 8](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7Bx-2%7D%2B%208)
![x = \sqrt[3]{y-2}+8](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7By-2%7D%2B8)
Now you need to isolate the "y"
Subtract 8 on both sides
Cube ( ³ ) each side to get rid of the ∛
![(x-8)^{3} = (\sqrt[3]{y-2}) ^{3}](https://tex.z-dn.net/?f=%28x-8%29%5E%7B3%7D%20%3D%20%28%5Csqrt%5B3%5D%7By-2%7D%29%20%5E%7B3%7D)
Add 2 on both sides
