Answer:
x= -1.5, y= -1
Step-by-step explanation:
6x= -5+4y
x= (-5+4y) / 6
4((-5+4y) / 6) + 5y = -11
4(-5+4y) + 5*6y = -11*6
-20+16y+30y= -66
16y + 30y = -66+20 = -46
y(16 + 30) = -46
y= -46 / (16 + 30)
y= -46 / 46
y= -1
x= (-5+4(-1)) / 6
x= (-5-4) / 6
x= -9 /6
x= -1.5
Its C)126in I think because top base is 16, bottom base is 12 and the height is 9.
Answer:
3
Step-by-step explanation:
7.2 ÷ 2.4 = 3
D) 8.17 x 10^8
910000000 - 93000000 = 817000000
817000000 ---> 8.17 x 10^8
