To solve this we must isolate x which involves having the variables on one side and the numbers on the other.
First add 2m to both sides
<em>3m+7/2=-2m+5/2</em>
<em>5m+7/2=5/2</em>
Then we subtract 7/2 from both sides
<em>5m+7/2=5/2</em>
<em>5m=-1</em>
Finally we divide both sides by 5
<em>5m/5=-1/5</em>
<em>Our final answer is -1/5</em>
<em>So the answer is B</em>
Hope this helps!
Answer:
16%
Step-by-step explanation:
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 12.5 minutes
μ is the population mean = 17 minutes
σ is the population standard deviation = 4.5 minutes
z = 12.5 - 17/4.5
z = -1
Probability value from Z-Table:
P(x<12.5) = 0.15866
Converting to percentage
= 0.15866 × 100
= 15.866%
Approximately , the percentage of people living in Flint have a travel time to work that is less than 12.5 minutes is 16%
Answer:
A
Step-by-step explanation:
Let us start with B = 90
That would mean that each of the other 2 angles must add to 90 which makes each of them 45.
But the question doesn't allow that. B has to be greater than 90 which means that the other two angles must be less that 45 each.
the only answer that does that is A
