The first one, the other graphs do not pass the Vertical line Test. they intersect at more than one point on the graph
Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230

Answer:
3/7 acres per hour
Step-by-step explanation:
To find acres mowed per hour, divide acres mowed by hours:
(3/4 ac)/(1 3/4 h) = (3/4)/(7/4) ac/h = 3/7 ac/h
Ginger's unit rate is 3/7 acres per hour.
Answer:
67 im pretty sure because the other vertical is 45 and then 67-22=45 so hope this helps.
Step-by-step explanation:
and ill write more if i want!
