30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
<u>Answer:</u>
The correct answer option is D. He multiplied the divisor by 100 and dividend by 10.
<u>Step-by-step explanation:</u>
We are given that Miguel completed the division where initially he had to divide 754 by 0.52.
To make it easier, he multiplied both the divisor and the dividend by the same number to get rid of the decimal in the divisor.
If he multiplied the divisor by 100, he should have multiplied the dividend by 100 too. But instead, he mistakenly multiplied the divisor by 100 and dividend by 10.
the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
Answer:
- B. the reader cannot accurately assess the airline because the evaluations are not necessarily representative of all evaluations.
- D. the reader cannot accurately assess the airline without reading all the evaluations.
Step-by-step explanation:
Using the most positive and the most negative comments to evaluate the airlines will not be an accurate measure of the airline because these are not a good enough sample. The opinions of those who fall in-between the most positive and negative should also be included as they could have some vital details as well.
Also, in order to be completely accurate, all the comments of the airline should have been posted because this would represent the entire population of comments and so would give the best assessment.
