Answer:
The absolute Values are not clear
Step-by-step explanation:
The equivalent expression the equation 12+4x is 4(3+x) using the distributive property.
To find the additive inverse, multiply 2/7 by -1.
Answer: -2/7.
Why is the answer -2/7?
When you add 2/7 + (-2/7) the answer will be 0.
This is why -2/7 is the additive inverse.
Answer:
12 in diameter bed will give better value
Step-by-step explanation:
Given:
Cost of cover 12 in diameter bed = $150
Cost of cover 18 in diameter bed = $300
Find:
Better value
Computation:
Area of bed = πr²
Area of 12 diameter of bed = (22/7)(6)²
Area of 12 diameter of bed = 113.14 in²
Area of 18 diameter of bed = (22/7)(9)²
Area of 18 diameter of bed = 113.14 in²
Area of 18 diameter of bed = 254.57 in²
Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar
Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar
So,
12 in diameter bed will give better value
