Aaron bought 8 red flags for the parade. Large flags cost $20 each. Medium flags cost $12 each. Aaron spent $112 in all. How many large flags (L) and how many medium flags (M) did he buy?
Answer:
Step-by-step explanation:
Price assuming he bought all large flags: [tex]20*8=160[/tex]
Amount of money more: [tex]160-112=48[/tex]
Difference of price in both flags: [tex]20-12=8[/tex]
Medium Flags: [tex]48\div8=6[/tex]
Large Flags: [tex]8-6=2[/tex]
----------------------------------
The reason why this works, is because the amount of money more comes from the difference between both flags.

twenty divided by two is ten
The sum of one-third a number and twenty-five is as much as twice the number
Answer:
The number is 15
Step-by-step explanation:
1/3(number) + 25 = 2(number)
subtract 1/3(number) from each side
25 = 2(number) - 1/3(number)
25 = 6/3(number) - 1/3(number)
25 = 5/3(number)
multiple each side by 3/5, which is the reciprocal of 5/3
25(3/5) = number
15 = number
Find the mean, median, and mode of 13, 30, 16, 19, 20, 22, 25, 31
Answer:
Mean: 22
Median: 21
Mode: No mode
Step-by-step explanation:
Mean:
The sum is the value of all the values divided by the number of values:
[tex]13+30+16+19+20+22+25+31/8[/tex] which is 22.
Median:
The median is the middle-most value of the data set when arranged from lowest to highest:
13, 16, 19, 20, 22, 25, 30, 31
Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.
Mode:
The mode is the most occurring value in the data set.
13, 16, 19, 20, 22, 25, 30, 31
Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.

For a triangle, m<1 =75 and m<3 =40 what does m<2 =?
Answer:
m<2 = 65
Step-by-step explanation:
The measures of angles 1 and 3 should be added together resulting in 115 degrees, and all triangles equal 180 degrees. Therefore, to find m<2, you have to subtract 115 from 180 resulting in a measure of 65 degrees.

What the answer to this math problem 6x-8=4(x+2)-7 ?
Answer:
x = 9/2
Step-by-step explanation:
6x - 8 = 4(x + 2) - 7
Distribute on the right side.
6x - 8 = 4x + 8 - 7
Combine like terms on the right side.
6x - 8 = 4x + 1
Add 8 to both sides. Subtract 4x from both sides.
2x = 9
Divide both sides by 2.
x = 9/2

Pete ate 3/7 of a pizza if Pete ate 9 slides of the pizza how many slices were ther all together
Answer:
21 slices
Step-by-step explanation:
given:
3/7 of a pizza ----> represents 9 slices
hence,
1/7 of a pizza -------> represents 9/3 = 3 slices
therefore
a whole pizza
= 7/7 of a pizza -------> represents 3 x 7 = 21 slices
Answer:
Hi there!!
Your answer is:
21 slices
Step-by-step explanation:
3/7ths = 9 slices
× 7/3
1 whole pizza = 21 slices
This is called the multiplicative inverse! 3/7 × 7/3 = 1

Identify the property used in each step of solving the inequality 3x – 2 > -4.
Step Justification
3x - 2-4 Given
3x > -2
X>-2/3
Answer:
2) is addition property
3) is multiplication property
Step-by-step explanation:
The addition property and division properties are used to solve the inequality.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 3x – 2 > -4.
Three times of x minus two is greater than minus four
By using addition property we add +2 on both the sides
3x – 2 +2 > -4+2
3x>-2
By using division property we divide +3 on both the sides
x>-2/3
Hence, the addition property and division propertys are used to solve the inequality.

Find where the lines y =-3x + 2 and y = 5x 6 cross in the coordinate plane.
Answer:
(1, -1)
Step-by-step explanation:
Given lines
y = -3x + 2y = 5x - 6They cross at:
-3x + 2 = 5x - 65x + 3x = 2 + 68x = 8x = 1The y coordinate is:
y = -3*1 + 2 = -1So the lines cross at point (1, -1)

Explain why the function is discontinuous at the given number
Answer:
left limit = 2 ≠ 1/2 = right limit
Step-by-step explanation:
A function is discontinuous if the limit of the function value approaching the point from the left is different than the limit approaching from the right.
Here, the left limit is 2 and the right limit is 1/2. The limits are different, which is why the function is discontinuous at x=-1.

inclusive of a 6.7% sales tax, a simone ring sold for $1707.20. Find the price of the ring before the tax was added.
The price of the ring before the tax was added is $1,600.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The price of the ring before the tax was added is,
106.7% ( x ) = 1707.20
