Answer: The boys made up 6b of the original class.
Step-by-step explanation:
5x + 2y =9
X + y= -3
5x+2y=9
2x+2y=-6
__________
3x =15
X =5
5+y=-3
Y=-8
Answer is : (5,-8)
Answer:
The answer to the equation is W’(4, –2), X’(3, –4), Y’(1, –4), Z’(0, –2)
Step-by-step explanation:
Because its turning 180 degrees that means its turning half the way it is. and if you look on the graph the z is Z (0, 2). which if you flip it upside down it would be (0,-2)
Also i took the test! :)
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0.
Now solve the equation: 12t=-20t+72,
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours.
Now the equation of the <span>pigeon is like this: x = 48t.
</span>Then for t = 2.25, we get

The Hyde has flown 108 km when the trains meet.</span>
Lets find the unit rate of both of the shirts.
5 for 63
4 for 54
63/5 = 12.60
54/4 = 13.50
Now we have our unit rates!
Greg = $12.60 per shirt
Zachary = $13.50 per shirt
Greg's shirt were cheaper than his brothers, so it has a better cost.
