Y intercept and also use the graph on ur calculator
AD = 9x + 3
DC = 57
ADC is a line, which is perpendicularly bisected by
BD.
Thus AD = DC
9x + 3 = 57
9x = 57 – 3
9x = 54
x = 54/9
<span>x = 6</span>
Answer:
Kayla plays on average 0.2 more chess games than Becker
Step-by-step explanation:
The first thing we must do is calculate the mean of each one.
Becker:
(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8
Kayla:
(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3
if we subtract these averages, we have to:
3 - 2.8 = 0.2
which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.
Let the admission price for adults be 'x' and that of children be 'y'
Equation Formation.
2 x + 3 y = 80............equation(i)
3 x + y = 99.............equation(ii)
y = 99 - 3 x
2 x + 3(99 - 3 x) =80
2 x +297 - 9 x = 80
- 7 x = -217
x = 31
y = 99 - 3x
y = 99 - 3×31
y = 99 - 93
y = 6
Answer ⇒ Adults = $31
Children = $6
