Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed
72 minutes
convert 8 hours to minutes ⇒ =8 × 60 = 480 minutes
15% of 480 = 0.15 × 480 = 72 minutes
Answer:
- The range of the given function is [6, + ∞)
Step-by-step explanation:
It is assumed the function is:
We know the square root is non-negative, so:
- x - 8 ≥ 0 therefore the function gets values
We can show this as:
