X + 9y = 8 x − 4y = –18

loris [4]

Step-by-step explanation:

$x + 9y = - 18 \\ 8x - 4y = - 18 \\ x = - 18 - 9y \\ 8( - 18 - 9y) - 4y = - 18 \\ - 144 - 72y - 4y = - 18 \\ - 76y = 126 \\ y = - 1.66 \\$

$x = - 18 - 9y \\ x = - 18 - 9( - 1.66) \\ x = - 18 + 14.94 \\ x = - 3.06$

Alex73 [517]

Answer:

$2.9-w=1.6$

Step-by-step explanation:

Let w be weight of emu egg in pounds.

We have been given that an ostrich egg weighs 2.9 pounds.The difference between the weight of this egg and the weight of an emu egg is 1.6 pounds.

We can represent this information as:

$2.9-w=1.6$

Therefore, the equation $2.9-w=1.6$ will give us the weight of the emu egg, w, in pounds.
