Answer:
-2-20p <em>OR</em> -20p-2
Step-by-step explanation:
2-4(5p+1)
Rewrite (the spaces can help me to view the different parts):
2 -4(5p + 1)
Distribute:
2 -20p -4
Combine like terms:
-2-20p
Answer:
-2-20p <em>OR</em> -20p-2
Using the absolute value function, we have that:
- The gasket with a weight of 0.53 lb should be thrown out.
- The inequality is: |x - 0.6| ≤ 0.06.
<h3>What is the absolute value function?</h3>
The absolute function is defined by:
It measures the distance of a point x to the origin.
For the batch, the weights are given as follows:
0.58, 0.63, 0.65, 0.53, 0.61.
Hence the mean is:
(0.58 + 0.63 + 0.65 + 0.53 + 0.61)/5 = 0.6.
Weights that are more than 0.06 of the pounds must be thrown out, hence the inequality for the valid weights is given by:
|x - 0.6| ≤ 0.06.
Hence the range of valid weighs is:
- x - 0.6 ≥ -0.06 -> x ≥ 0.54.
- x - 0.6 ≤ 0.06 -> x ≤ 0.66.
0.53 is not in the interval, hence the gasket with a weight of 0.53 lb should be thrown out.

I'm not 100% sure, but imma have a go.
Answer:
a = 261; b = 253
Step-by-step explanation:
label candy bar A as a
label candy bar B as b
<u>Make 2 equations.</u>
2b + a = 767 (1)
b + 2a = 775 (2)
<u>Solve for a in (1)</u>
2b + a = 767 (-2b)
a = -2b + 767
<u>Substitute for into (2)</u>
b + 2( -2b + 767 ) = 775 (flip)
2( -2b + 767 ) + b = 775 (solve)
−4b + 1534 + b = 775 (add b)
-3b + 1534 = 775 (subtract 1534 from both sides)
−3b = −759 (divide both sides by 3)
b = 253
<u>Substitute b into (1)</u>
a = -2b + 767 (substitute)
a = -2 (253) + 767 (solve)
a = -506 + 767 (add)
a = 261
Geometric mean =√(45*5)=√(5*5*9)=15
Square root because we have 2 numbers.
Answer is A.15
