a basketball team sells tickets that cost $10, $20, or for VIP seats, $30. The team has sold 3241 tickets overall. It has sold 101 more $20 tickets that $10 tickets. The total sales are $59830. How many tickets of each kind have been sold?
Answer:
x = 1,213
y = 1,314
z = 714
Step-by-step explanation:
$10 = x
$20 = y
$30 = z
10x + 20y + 30z = 59,830
____________
Solving for x:
Since there 101 more $20 tickets than $10 tickets we are making the equation of:
y = x + 101
First equation (substitute the equation above for y)
x + (x+ 101) + z = 3,241
Subtract 101 from 3,241
2x + z = 3,140
Second equation (substitute y with 'x + 101 ')
10x + 20(x + 101) + 30z = 59,830
10x + 20x + 2,020 + 30z = 59,830
Subtract 2,020 from 59,830
10x + 20x + 30z = 57,810
Add 10x and 20x
30x + 30z = 57,810
Cancel out the 30's and divide 57,810 by 30
x + z = 1,927
Now solve using the first 2 equations
2x - z =3,140 = x + z = 1,927
Subtract z
2x = 3,140 = x + 1,927
Divide x
x = 3,140 = 1,927
Subtract 1,927 from 3,140
x = 1,213
____________________
Solving for y:
y = x + 101
y + 1,213 + 101
y = 1,314
____________________
Solving for z:
1,213 + 1,314 + z = 3,241 (Overall tickets sold)
2,527 + z = 3,241
Subtract 2,527 from 3,241
z = 714
____________________
Check math:
10x + 20y + 30z = 59,830
10(1,213) + 20(1,314) + 30(714) = 59,830

A bag contains
18
red balls and
4
blue.
What percentage of balls are red?
Answer:
81% of the balls are red
Step-by-step explanation:
If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball
18 red + 4 blue = 22 balls part (a)
18/22 = 9/11 part (b) simplify
9/11 * 100 part (c) multiply the fraction by a hundred to get the percentage
81.81 ~ 81% part (d) solve
Answer:
81 9/11%
Step-by-step explanation:
First add the number of red and blue balls together. 18 + 4 = 22
What is the number of red balls? It’s 18
We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.
Therefore, the answer is 81 9/11%.
Which value of p makes the equation 7p+3=4p+9 true?
p=2
p=3
p=0
p=5
p=2
Step-by-step explanation:
7×2=14
14+3=17
4×2=8
8+9=17
they both get the same end product, meaning 7p+3=4p+9 is TRUE
*edit
Answer:
[tex] \sf \: a) \: p = 2[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of p.
The equation is,
→ 7p + 3 = 4p + 9
Then the value of p will be,
→ 7p + 3 = 4p + 9
→ 7p - 4p = 9 - 3
→ 3p = 6
→ p = 6 ÷ 3
→ [ p = 2 ]
Hence, the value of p is 2.

A worker has job offers from two companies. The information below summarizes the job offer from each company.
Company A:
Starting salary of $31,000
Raise of $3000 each year
Company B:
Starting salary of $38,000
Raise of $2000 each year
Part A: Write an equation in terms of n years that can be used to determine the number of years when the salaries would be the same for both companies.
Part B: Use the equation you wrote in part A to determine the number of years it would take for the salaries to be the same for both companies. Use mathematics to support your answer.
Answer:
Part A: 31000 + 3000x = 38000 + 2000x; Part B: 7 years.
Step-by-step explanation:
x = number of years since start
For Company A, we have that salaryA(x) = 31000+3000x,
For Company Part B: salaryB(x) = 38000+2000x
We want x such that salaryA(x) = salaryB(x).
Thus,
31000 + 3000x = 38000 + 2000x (Answer to part A)
Subtracting 31000 from both sides of the equation implies that:
3000x = 7000 + 2000x.
Subtracting 2000x from both sides implies that:
1000x = 7000.
Then, dividing both sides of the equation by 1000 yields:
x = 7 years (Answer to part B)

2400/40=60
Krutika types 60 words per minute.
Since Caroline has the highest wpm, we can safely say that Caroline types the fastest rate of words per minute.
how do i solve xk=v-w solve for x
Answer:
x = (v-w)/k
Step-by-step explanation:
Step 1: Isolate x by dividing both sides of the equation by k.
[tex]\frac{xk}{k} = \frac{v-w}{k}[/tex] [tex]x = \frac{v-w}{k}[/tex]Therefore, the answer is [tex]x = \frac{v-w}{k}[/tex].
Answer:
x = [tex]\frac{v-w}{k}[/tex]
Step-by-step explanation:
xk = v - w ( isolate x by dividing both sides by k )
x = [tex]\frac{v-w}{k}[/tex]

(2, -2)
Step-by-step explanation:
Solve 7x - 2y = 18 for x:
[tex]7x - 2y = 18[/tex] [tex]7x - 2y + 2y = 18 + 2y[/tex] (Add 2y to both sides)[tex]7x = 2y + 18[/tex] [tex]\frac{7x}{7} = \frac{2y+18}{7}[/tex] (Divide both sides by 7)[tex]x = \frac{2}{7}y+\frac{18}{7}[/tex]Substitute 2/7y+ 18/7 for x in -4x + 3y = -14

[tex]x = \frac{2}{7}y + \frac{18}{7}[/tex] [tex]x = \frac{2}{7}(-2) + \frac{18}{7}[/tex] [tex]x = 2[/tex] (Simplify both sides of the equation)Given that x = 2 and y = -2, the point is: (2, -2)
Therefore, the solution is (2, -2).
