As a fundraiser, a club is selling posters. The printer charges a $15 set-up fee, plus $0.85 for each poster. The cost y in dollars to print x posters is given by y = 0.85x +15.
(a) What is the cost y in dollars to print 30 posters? To print 100 posters?
(b) Find the number of posters x if the printer billed the club for costs of $185.
(c) Write the information from parts (a) and (b) as three ordered pairs.
(d) Use the data from part (c) to graph the equation.
(a) The cost y to print 30 posters is $___ and to print 100 posters is $___.
Answer:
See below for answer
Step-by-step explanation:
A. y = 0.85x + 15 when x = 30
y = 0.85(30) + 15
y = 40.5
y = 0.85x + 15 when x = 100
y = 0.85(100) +15
y = 100
B. y = 0.85x + 15 when y = 185
185 = 0.85x + 15
185 - 15 = 0.85x
170 = 0.85x
170/0.85 = x
200 = x
C (30, 40.5)
(100, 100)
(200, 185)
19+1=x
what does x equal?
(hint: it's math and common sense)
Answer:
X equals 20
Step-by-step explanation:
19+1=x rearranged is X-19=1 and 20 minus 19 is 1 therefore 20 is the value of X.
Answer:
x = 20
Step-by-step explanation:
19 + 1 = 20

Suppose a charity received a donation of $24.1 million. If this represents 29% of the charity's donated funds, what is the total amount of its donated funds?
Round your answer to the nearest million dollars.
Answer:
$83 million
Step-by-step explanation:
29% of the charity's donated funds.
$24.1 million = donation
Let x = the total amount of donated funds
29/100 • x = 24.1
x = 24.1 • 100/29
x = 83.10
=83
Hope this helps :)

1.Natalie and her friends decided to rent 4 lanes at regular cost for a party. Ten people need to rent shoes, and 4 people are members. What is the total cost for the party?
medium sodas cost $1.25 and hot dogs cost $2.50
2. Natalies group brought in pizzas, but is buying the drinks at the concession stand. How many medium sodas can Natalies group buy with $20? Make a table to show your answer.
Answer:
1. Hence, the answer is $74.50
2. Hence, the answer is 16.
Step-by-step explanation:
1. Given: Natalie and her friends decide to rent 4 lanes at regular cost for a party. Ten people need to rent shoes, adn 4 people are members.
To find: What is the total cost for the party?
Solution:
Since Natalie and her friends wanted to rent four lanes, we need to calculate this at REGULAR cost.
4 * 9 .75 = 39
Now since 10 people want to rent shoes, and 4 people are members, we subtract.
10 - 4 = 6
6 nonmembers
4 members
6 times the amount of shoe rental for 6 * 3.95 - 23.70
non members
4 times the number of members shoe rental 4* 2.95
11. 80
Now add the quantities
39 + 11.80 + 23.70 += 50.80 + 23.70 =
74.50
Now, our answer is 74.50
2.
Solution:
20 / 1.25 = 16
So the possible amount that can be bought is 16 medium sodas.

Quadrilateral JKLM with vertices J(2, 10),
K(8,9), L(7,4), and M(3, 4):
J
k = 2, centered at (4,7)
Given:
Quadrilateral JKLM has vertices J(8, 4), K(4, 10), L(12, 12), and M(14, 10).
(a)If we translate quadrilateral JKLM 3 units down and 3 units left:
(x-3,y-3), we obtain: W(5,1), X(1,7), Y(9,9), and Z(11,7)
Therefore, we match it with: A translation 3 units down and 3 units left
(b)If we translate quadrilateral JKLM 2 units right and 3 units down:
(x+2,y-3), we obtain: O(10,1), P(6,7), Q(14,9), and R(16,7)
Therefore, we match it with:A translation 2 units right and 3 units down
S(4, 16), T(10, 20), U(12, 12), and V(10, 10)
(c) If we transform quadrilateral JKLM by a sequence of reflections across the x- and y-axes, in any order, we obtain:
A(-8, -4), B(-4, -10), C(-12, -12), and D(-14, -10)
(d)If we translate quadrilateral JKLM 3 units left and 2 units up:
(x-3,y+2), we obtain:E(5,6), F(1,12), G(9,14), and H(11,12)
Therefore, we match it with: A translation 3 units left and 2 units up
(e)S(4, 16), T(10, 20), U(12, 12), and V(10, 10)
No suitable transformation is found from JKLM to STUV.

what is the value of x
a) 69
b) 35
c) 14
d) 26
Answer:
50²-48²
solve it you will get answer
Answer:
C) 14
Step-by-step explanation:
(Phytogoras theorem)
[tex] {50}^{2} = {48}^{2} + {x}^{2} [/tex]
2500 = 2304 + x^2
2500 - 2304 = x^2
X^2 = 196
[tex]x = \sqrt{196} [/tex]
X = 14

Given that 6x – 7y=4
Find x when y = 2
Answer:
x = 3
Step-by-step explanation:
6x - 7y = 4
We are given that y = 2
6x - 7(2) = 4
6x - 14 = 4
Add 14 on both sides to leave the 6x alone
6x = 18
Divide by 6 to isolate x and find the value of x
x = 3
We can further prove this by putting in the value of x
6(3) - 7(2) = 4
18 - 14 = 4
Which is correct

3x=15 question answer
Answer:
x=5
Step-by-step explanation:
To solve for the value of x, you have to get x by itself. So to get rid of the 3, divide both sides by 3. 3x/3 leaves x. 15/3 leaves 5. So you're left with x=5.
The solution of expression 3x = 15 is,
⇒ x = 5
We have to given that,
An expression to simplify,
⇒ 3x = 15
We can simplify the expression for value of x,
⇒ 3x = 15
Divide both side by 3,
⇒ 3x/3 = 15 / 3
⇒ x = 5
Therefore, The solution of expression 3x = 15 is,
⇒ x = 5

Keith wants to buy an IPad for $500. He wants to earn enough money delivering pizzas to cover at least two-fifths of the cost.
Part A.
If he earns $12.50 per hour at work, write an inequality that represents how many hours Keith's needs to work
Part B
Solve your inequality? Justify your answer.
Answer:
Step-by-step explanation:
500 / 5 = 100 (that's 1 fifth, so 2 fifths will be 200)
200 / 12.5 = 16 (he will have to work 16 hours to get $200)
the inequality would be:
x * 12.5 >= 500 * 0.4 (something like that)
