<span> 2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17)
...........15x+6y=51</span>........equation 2
adding equation 1 and equation 2;
19x=57
x=3
2x-3y=3
(2*3)-3y=3
6-3=3y
y=1

Srue what's your question
Step-by-step explanation:
If 5 is a factor of the number, then its ones place is either a 5 or a zero.
Answer:
C
Step-by-step explanation:
note that sin x = cos(90 - x ) ← Cofunction identity
If x = 36 then 90 - x = 90 - 36 = 54
Hence sin 36° = cos 54° → C
Answer:
B. 4, Heads
4, Tails
5, Heads
5, Tails
6, Heads
6, Tails
Step-by-step explanation:
Given that the cube is labelled 1 to 6 and the coin has a head or a tail, the only outcome when the number cube lands on a number greater than 3 means that the cube lands on 4 or 5 or 6.
On the other hand, the coin may give a head or a tail.
In light of this, the possible answers are;
4, Heads
4, Tails
5, Heads
5, Tails
6, Heads
6, Tails
Hence option B is right
