Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
Answer:
5x+4y<=20
Step-by-step explanation:
We are expected to model the expression for the cost of the softball and the Hardball combined.
le the number of hardballs be x
let the number of softs balls be y
the cost of the hardballs is =5x
the cost of softball is =4y
therefore given that the total cost is =$20
the expression for the cost of x and y balls is given as
5x+4y<=20
She ran the last 100 meters in 2:15 -1:25 = 0:50, so her average speed was
... (100 m)/(50 s) = 2.0 m/s
Answer:
