Number is x
3 times of x is increased by 22, that euals 14 less than 7 times x
3x+22=-14+7x
minus 3x both sides
22=-14+4x
add 14 to both sides
36=4x
divide both sides by 4
9=x
the number is 9
To find area (of squares and rectangles), you multiply the sides together. 1.5 (or one and a half; can't make mixed fractions well) times 1.5 doesn't make 1.5. In reality, it makes 2.25. Perimeter doesn't have much to do with area.
The answer is simple.
First, you must look what is the least among the list. In this case, it is 16x.
Then get the factors of 16x and they are (4,4) , (8,2) and (16,1).
Since you can't then divide it to 36.
Since you can't divide 36 by 16 and 8. You must eliminate them from the list of GCF.
2 and 4 are possible but 4 is the greatest Common Factor which can be divided to both 16 and 36.
First arrange the numbers from least to greatest:
67, 76, 76, 82, 84, 93
The median is the middle number. But since we have two numbers that are in the middle we have to find the average of them.
76 + 82 = 158
158/2 = 79
So your answer is 79
