2x + 3y = –19
–2x − y = 1
1 answer:
The x both cancels out
So you’re left with 2y=-18 (add 3y to negative y and -19 and 1)
Divide by 2 and y equals -9
Plug in y to get x
2x + 3(-9) = -19
2x + -27 = -19
Add 27 to both sides
2x= 8
Divide by 2, x= 4
So x= 4 and y = -9

Well the formula is : b1+b2/2 (h)
so the height would be solved as :
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9) *reciprocal*
h = (27) / (9)
h = 3
Answer:
4,500 x 5 = 22,500
4,500 divided by 5 = 900
4,500 plus 5 = 4,505
4,500 minus 5 = 4,495
