Answer:
Last one:
2 x + 4 y = 6. 3 x minus 4 y = 9.
Step-by-step explanation:
2x + 4y = 6
3x - 4y = 9
4y = 3x - 9
2x + 3x - 9 = 6
5x = 15
x = 3
4y = 3(3) - 9
4y = 0
y = 0
Only one solution, which is (3,0)
All numbers ending in 0 are divisible by 5, 10 and 2
Answer:
Because the base of this expression is not same.
Step-by-step explanation:
work is shown and pictured
this problem is tricky, if you actually draw it out you will see the side opposite to A is the adjacent side to C which means sin(A)=cos(C)=5/13
Hope this helped!
