The first option is the correct choice of answers.
Answer:
B, 24 (second answer choice)
Step-by-step explanation:
4r+7s=23
r-2s=17
8r+14s=46
7r-14s=119
15r=165
r=11
11-2s=17..........by putting value of r in ii
-2s=17-11
2s= -6
s= -3
3r+3s=3*11+3(-3) you get this by putting values of r and s
=33-9
=24 (B)
25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100
15%=15/100
15% of 25=(15/100)25=(25*15)/100
Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100
3.75=3.75
The defenition of a trapezoid is only 1 pair of paralell sides
a paralellogram is defined as having 2 pairs of paralell sides
therefor a trapezoid cannot be a paralellogram
rectangles, rhombuses and squares are all paralellograms
since trapezoid≠paralellograms and
rectanges&rhombuses&squares=paralellograms
therfor trapezoids≠rectanges&rhombuses&squares
