it costs $12 for admission to the Fair, plus $0.50 for each ticket yo play games. if you have a total of $30 to spend, what is the greatest amount of tickets you can buy?
Answer:
36 tickets
Step-by-step explanation:
First you set up your equation, which would be 12 + 0.50x = 30. Next you subtract 12 on both sides to get 0.50x = 18. Divide both sides by 0.50 to get x = 36.

Step-by-step explanation:
Walter and Brian each have a CD collection. The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection. The total number of CDs in both collections is 144. What is x, the number of CDs in Walter's collection?
Answer:
36CDs
Step-by-step explanation:
The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection.
Hence, Brian's collection = 3x
The total number of CDs in both collections is 144.
We have the Equation:
x + 3x = 144
4x = 144
x = 144/4
x = 36
Therefore, the number of CDs in Walter's collection is 36 CDs

which simplifies to 1/15
A barrel filled with oil is a cylinder with a diameter of 22 inches and a height of 35.5 inches. There are 231 cubic inches in a liquid gallon, how many gallons of oil does the barrel hold
Answer: The barrel holds about 58.44 gallons of oil .
Step-by-step explanation:
Given : For cylinder , diameter = 22 inches and height = 35.5 inches
radius = 11 inches [half of diameter]
Volume of cylinder [tex]=\pi r^2h[/tex], where r= radius and h = height.
Volume of cylinder [tex]=\dfrac{22}{7}\times(11)^2\times 35.5=13500.14\text{ cubic inches}[/tex]
Since, There are 231 cubic inches in a liquid gallon, so.
1 cubic inch = [tex]\dfrac{1}{231}[/tex] gallon.
13500.14 cubic inch = [tex]13500.14\times\dfrac{1}{231}\approx58.44\text{ gallons}[/tex]
Hence, The barrel holds about 58.44 gallons of oil .
Four students were discussing how to find the unit rate for a proportional relationship. Which method is valid?
"Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit
rate."
O "Look at the graph of the relationship. Count the number of units up and the number of units to the right one must
move to arrive at the next point on the graph. Write these two numbers as a fraction."
O "Look at the graph of the relationship. Find the x-value of the point that corresponds to y = 2. That value is the unit
rate."
O "Look at the graph of the relationship. Find two points which have y-values that are one unit apart. The unit rate is
the difference in the corresponding x-values."
Margaret is reading a book. The number of pages she has left to read is 276−35d, where d represents the number of days she has been reading. What does each part of the expression represent? Drag the answer into the box to match each part of the expression.
Given:
The number of pages she has left to read is 276−35d, where d represents the number of days she has been reading.
To find:
The explanation of each part of the expression.
Solution:
The given expression is
[tex]276-35d[/tex]
Here, 276 is initial number of pages or total number of pages.
d is number of days she has been reading.
-35 represents the remaining pages decreased by 35 per day.
35d is number of pages she reads in d days she has been reading.
Therefore, total number of pages is 276 and number of pages she reads each day is 35.

−a2 − (2a − 7b) + b for a = −2 and b = 3
Answer:
24
Step-by-step explanation:
Given
- a² - (2a - 7b) + b ← substitute a = - 2, b = 3 into the expression
= - (- 2)² - (2(- 2) - 7(3)) + 3
= - 4 - (- 4 - 21) + 3
= - 4 - (- 25) + 3
= - 4 + 25 + 3
= 24
Answer: 32
Steps: -(-2)2 - [ 2(-2) - 7(3) ] + 3
• Follow the PEMDAS order of operations
Calculate within parentheses [ 2(-2) - 7(3) ] : -25
= -(-2)2 - (-25) + 3
Multiply and divide (left to right): 4 - (-25) + 3
Add and subtract (left to right): 32

-4 = 3 + 7(x - 1)
What does x equal
Answer:
x = 0
Step-by-step explanation:
Given
- 4 = 3 + 7(x - 1) ← distribute and simplify right side
- 4 = 3 + 7x - 7
- 4 = 7x - 4 ( add 4 to both sides )
0 = 7x , then
x = 0
Complete the expression in terms of P and Q so the result is -5b^2+8b-3. Drag the terms to the correct location on the expression. Not all terms will be used.
Answer:
(-5b+3)(b-1)
Step-by-step explanation:
We need to factorize the given expression
-5b^2+8b-3
-5b^2+5b+3b-3
(-5b^2+5b)+(3b-3)
factor out the common terms:
-5b(b-1)+3(b-1)
(-5b+3)(b-1)
Hence the expression equivalent to -5b^2+8b-3 is (-5b+3)(b-1)

Answer:
The length of h is 3cm.
Step-by-step explanation:
You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.
2(7 7/8 cm^2)= (1/2(5 1/4)(h))2
(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)
3=h
Answer:
The answer is h+ 3cm
