Answer:
<h2><u><em>
2/7</em></u></h2>
Step-by-step explanation:
I answer for what I understand, the question is not clear.
2 divided by what times what equals 7
2 : x = 7
x = -2/-7
x = 2/7
-------------
check
2 : 2/7 = 7
2 * 7/2 = 7
7 = 7
the answer is good
Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
Let's say Samantha has s marbles and Paul has m marbles.
We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.
Substitute 20 in for s:
20 = 6m
m = 20/6
Thus, the equation is m = 20/6.

4b+3s=72
6b+3s=96
Multiply the second equation by -1
-6b-3s=-96
Now you can cross out the +3s -3s
-2b=-24
Divide both sides by -2
b=12
s=8
So blouses cost $12 each and skirts cost $8 each
Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
ANSWER
0.9738 or 97.38%
EXPLANATION
Given:
Desired Outcome:
Probability that it will last 10 years
z-score for the sample:
p-value
For the z-score of 1.9376, the p-value is 0.9738 or 97.38%
Hence, the probability that it will last longer than 10 years if you randonly purchase one item is 97.38%
