84
Step-by-step explanation:
This question is solved using proportions.
From the sample:
11 + 3 = 14 out of 13 + 11 + 3 = 27 would rate the test something other than easy.
Out of 162:
Applying the rule of three:
14 - 27
x - 162
Applying cross multiplication:



Thus the correct answer is given by option C.
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>The equations are:</u>
<u>Add up the equations to eliminate y and solve for x:</u>
- x - y + 2x + y = 2 + 13
- 3x = 15
- x = 15/3
- x = 5
<u>Now find the value of y:</u>
- y = x - 2
- y = 5 - 2
- y = 3
Answer:
The percentage is 1/2 * 2/5 = 1/5 = 20%.
Answer:
what do you want for the answer 12 goes in to 36 3 times
18 goes into 54 3 times and 25 goes into 75 3 times
Step-by-step explanation:
so im guessing k=1/3
because x=1/3 of y
