1 is going to be 180-40 as angles on a straight line add to 180.
2 will be 40, as they are "alternate" (form a Z shape in the parallel lines so are equal)
3 will then also be 180-40
Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100
He sold 100 rackets for $ 20
Part a y=95x
Part b 285=95•3
Part c ?
Hope I helped sorry I don't know how to do the last one!
A, just divide by 4 and youll get your solution.
