-1/3. Use the formula x1-x2/y1-y2
Step-by-step explanation:
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5·x + 20 = 135
5·x = 115
x = 23
So the sequence is
23, 25, 27, 29, 31
The second number is 25.
Do you agree?
First, you find the biggest number that you can divide 24, 30, and 12 by. I would go with 6, because it will simplify all the numbers into the simplest forms possible in this equation. Then, divide each number by 6.
24/6= 4
30/6= 5
12/6= 2
The answer:
4 : 5 : 2
Hope I could be of help:)
Answer:
17 %
Step-by-step explanation:
12 of 72 cars needed mufflers
% = cars needing mufflers/total cars × 100 %
= 12/72 × 100 %
= 17 %
17 % of the cars serviced needed muflers.
