Sweater: 1/3 = 0,333
Jeans: 3/5 = 0,6
1 – 0,6 – 0,333 = 0,067
So the 36$ represents 6,7% of all the money he had at first. (just for you to know 1 represents 100% of the money he had)
Now, you just have to use the rule of three
0,067 = 36
0,333 = x
(0,333•36)/0,067= 179,1$
The sweater costed 179,1$
No because the scale factor is inconsistent while it would be neccecary to be consistent if it was similar. 19.9/15.3=1.3 while 29/25=1.16 which proves that they have an inconsistent scale factor.
Answer (2,-5) when it is reflected across x=3
Answer:
Let the 3 digits are xyz.
For x we have 6 options, for y - 5, for z - 4 since all digits are different.
<u>Number of options:</u>
Even numbers will have z = 2, 4 or 6, then
x - 5 options, y - 4 options
<u>Number of options:</u>
