We need to solve for x. Let's try problem b:

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:

Let's isolate x, so subtract 1 from both sides:

Since x can't have a coefficient, divide both sides by 3:


So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:

Let's get our whole numbers on the right side. Add 1 to both sides:

Subtract 4x from the right side on both sides:

Since this is not true, your answer would be:
No solution
Answer:

Step-by-step explanation:
so you already have the formula, which is
![\sqrt[3]{ \frac{3v}{4\pi} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B3v%7D%7B4%5Cpi%7D%20%7D%20)
the v represents Volume.
and 3v would be 3×volume.
![\sqrt[3]{ \frac{3 \times 1000}{4 \times \pi} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B3%20%5Ctimes%201000%7D%7B4%20%5Ctimes%20%5Cpi%7D%20%7D%20)
![\sqrt[3]{ \frac{3000}{12.56637061} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B3000%7D%7B12.56637061%7D%20%7D%20)
![\sqrt[3]{238.7324147 }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B238.7324147%20%7D%20)

to the nearest tenth place.

Answer:
401 MILES
Step-by-step explanation:
miles from A to B:
64 * 5.5 = 352 miles
miles from A to C:
352 + 49 = 401 miles
