Answer:
115
Step-by-step explanation:
20% is one fifth. If Mary has one fifth fewer than Susan, then she has 4 fifths of what Susan has. So 92 is 4 fifths of some number.
To find out what one fifth is, you can divide 92 by 4 because it is four fifths.
92/4 = 23
So one fifth of the number of blouses Susan has is 23. Now you can multiply 23 by 5 to get the total number of blouses Susan has.
23 * 5 = 115
Answer:
Step-by-step explanation:
8(3x + 4) = 2(12x − 8)
Open brackets
24x + 32 = 24x - 16
Collecting like terms
24x - 24x = -16 - 32
No Solution since the x as cancelled out
Answer:
5
Step-by-step explanation:
To find the median number of
3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7
Number them from least to greatest
2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53
Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5
Hope this helps!
