Answer:
both statements are fine
Step-by-step explanation:
To find the price of a product after decreasing it, they can be done in the two ways that the statement tells us,
First, calculate that% that was decreased and then subtract it from the original price or simply multiply that original price by the percentage in which the new price would remain.
For example:
let "x" be the original price
in the first case it would be:
0.2 * x and then subtract from x, i.e .:
x - 0.2 * x
in the second case it is:
1 - 0.2 = 0.8
that is, the new price would be 0.8 * x
1/3+5/12=4/12+5/12=9/12=3/4 of guests choose meat
1-3/4=1/4 of guests are vegetarians
so
23 guests is 1/4 of all guests
23*4=92 all guests
The answer is: E

Answer: x = 35</h3>
==========================================================
Explanation:
All three angles must add to 180. This is true for any triangle.
x+x+110 = 180
2x+110 = 180
2x = 180-110 ... subtract 110 from both sides
2x = 70
x = 70/2 .... divide both sides by 2
x = 35
As a check: 35+35+110 = 180 which helps confirm the answer.
