Answer:
$2.35 for one video
Step-by-step explanation:
You set up two equations:
$7.50= p + 2v
$12.20= p + 4v
You then set both equal to p
p=-4v+12.20 and p=-2v+7.50
So you can set them equal to each other and solve for v (the cost of one video)
v= $2.35
1 1/7 = 8/7
The lowest common denominator of 8/7 and 1/9 is 63
72/63 : 7/63
72:7
<h3>
Answer is -96-36v</h3>
Work Shown:
The "6+10" in the parenthesis combines to 16. So we really have -6(16+6v)
Use the distribution rule. Multiply the outer -6 by each term inside
-6 times 16 = -96
-6 times 6v = -36v
Put together, we have -6(16+6v) = -96-36v
Answer: 188 children and 200 adults were admitted.
Step-by-step explanation:
Let x represent the number of children that were admitted that day.
Let y represent the number of adults that were admitted that day.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
