Answer:
42
Step-by-step explanation:
The correct choice is marked.
If you follow instructions, you will compute the quotient for each value in the set:
2520 ÷ 30 = 84
2520 ÷ 42 = 60 . . . . . the value we're looking for (we need go no further)
2520 ÷ 84 = 30
__
The easier way to solve the problem is to multiply the equation by x/60, so you have ...
2520 ÷ 60 = x
Then, you're doing one division instead of two or three.
2520 ÷ 60 = 42 = x
<u>Answer:</u>
96
<u>Step-by-step explanation:</u>
Let's assume that the marks needed in the next exam is 
. Then if the average becomes 90,
Now we can simply solve for :
⇒ 
⇒ 
[Multiplying both sides by 4]
⇒ 
[Subtracting 264 from both sides]
⇒ 
Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.
<u>|Vertices </u><em><u>ABCD</u></em><u>| (x - 3, y + 5) |Vertices </u><em><u>A'B'C'D'|</u></em>
| (-4, 1) | (-4 - 3, 1 + 5)| (-7, 6) |
| (1, 3) | (1 - 3, 3 + 5) | (-2, 8) |
| (2, 0) | (2 - 3, 0 + 5) | (-1, 5) |
<u>| (-3, -2) |(-3 - 3, -2 + 5)| (-6, 3) |</u>
The vertices of (-4, 1), (1, 3), (2, 0), and (-3, -2) is (-7, 6), (-2, 8), (-1, 5), and (-6, 3).
The answer is D.
Answer:
(30-6) ÷1.25
Step-by-step explanation:
30-6=24
|
24÷1.25=19.2
↓
you round that and you get 19
