Step-by-step explanation:
Using the rules of radicals/ exponents
×
= 
⇔ ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Simplifying each term
7
= 7
x
= x ×
× 
= x × 3 × 
= 3 × 
= 3
Subtracting the 2 simplified like terms, that is
7
- 3
= 4
← return to radical form
= 4
Answer:
Step-by-step explanation:
x + 8 < - 28
x < - 28 - 8
x < - 36
Option A is the correct answer
Rounded to the nearest cent, the answer is 1.19
7 hours X 60 minutes = 420 minutes
420 minutes + 20 minutes = 440 minutes
