Answer:
See explanation below.
Step-by-step explanation:
Let's say,
x = number of tokens required to play one game of ping pong
y = number of token required play one game of pinball
Using the data given, the system of equations are:
Solving the system of equations using substitution method will give us:
So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
Solutions
Annie puts $10 into a vacation jar each week and we need to find out <span>how much will she have saved by the end of the year. To solve the problem first we have to find out how many days there are in a year and convert them into weeks.
Days in a year = 365
To find weeks divide by 7 since a week consists of 7 days.
365 </span>÷ 7 = 52
<span>
1 year has 52 weeks
our next step is to multiply 52 by 10.
52 x 10 = 520
By the end of the year she would have saved 520 dollars. </span><span />

Step-by-step explanation:
(x1,y1) = (6,-1)
(x2,y2) = (3,-7)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y + 1)/(-7 + 1) = (x - 6)/(3 - 6)
(y + 1)/-6 = (x - 6)/-3
(y + 1)/2 = (x - 6)/1
y + 1 = 2(x - 6)
y = 2x - 12 - 1
y = 2x - 13
Answer:
False
Step-by-step explanation:
