Answer:
y=4, x=8
Step-by-step explanation:
system:
x+y = 12, x=2y
convert to 1 variable, simplify:
2y+y=12
3y=12
y=4
x=2y=4*2=8
Answer:
AB would be 18 or the first choice.
Since BD is the median that means from A to D and from D to C are equal. We set this up as an equation and solve it.
<em>x + 8 = 2x - 17</em>
<em> </em><em><u>+ 17 +17</u></em>
<em>x + 25 = 2x</em>
<em><u>-x -x</u></em>
<em> 25 = x</em>
This gives us our first bit of the answer. Then we plug this into our equation for the length of AB to get 18.

Divide the number by the number before it to get the common ration.
ex: 12/3 = 4
Answer:
d
Step-by-step explanation:
If you would like to know how much money did Scott have left after his purchase, you can calculate this using the following steps:
20.00 - 2 * 1.59 - 2 * 1.75 = 20.00 - 3.18 - 3.5 = 13.32
Result: Scott had 13.32 after his purchase.
