X=number of senior tickets
y=number of student tickets
1st day
7x+1y=101
2nd day
7x+12y=134
easy, we can eliminate the x's
multiply first equation by -1
-7x-1y=-101
<u>7x+12y=134 +</u>
0x+11y=33
11y=33
divide by 11 both sides
y=3
sub back
7x+y=101
7x+3=101
minus 3 both sides
7x=98
divide both sides by 7
x=14
senior tickets cost $14
student tickets cost $3
that sounds unfair
The first thing we must know in this case is that the distance is equal to the speed for time.
We have then:
For Chris:
d1 = 40 * t
For Amy:
d2 = 60 * (t-2)
The distance between both will be given by the hypotenuse of the rectangle triangle:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
Answer:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
option 3
The answer is D. <span>$780.25

In this particular case, you just need to find the difference between what Casey earn hourly with his total earning..
The hourly wage that Casey earned in 26 hours:
$ 4.55 x 26 = 118.3
The total amount that casey earned in 26 hours:
$898.55
So, the amount that Casey earned through tips:
$898.55 - $118.3 = $780.25
Answer:
x = -44.3
Step-by-step explanation:
2x+450 = 7-8x
Add 8x to each side
2x+8x+450 = 7-8x+8x
10x+450 =7
Subtract 450 from each side
10x+450-450 = 7-450
10x = -443
Divide each side by 10
10x/10 = -443/10
x = -44.3
Answer:
Step-by-step explanation:
well first off when you work through the promblem you will have to think about the promblem like the variables will cancel out and will have a equation consisting of only contasts.
