the expression 3x-9 and 23-5x represent the lengths (in feet) of two sides of an equailater triangle. find the perimeter of the triangle
Answer: 3ft
Step-by-step explanation:
Step 1; 3x-9=23 5x
Step 2; 3x9=23 5x 3x+ 9=23- 5x
Step 3 ; 3x-9 3x4-9 = 3ft
3ft is the answer.

angle 3 and angle 4 are supplementary. m<3=7x-3 and m<4=2x+12. Find the measure of each angle
Step-by-step explanation:
Sum of supplementary angle = 180⁰
2x + 12 + 7x - 3 = 180
9x + 9 = 180
9x = 180 - 7
9x = 171
x = 171/9
x = 19
m<3 = 7(19) - 3 = 133 - 3 = 130⁰
m<4 = 2(19) + 12 = 50⁰
show that a^12 can be written as a perfect square and a perfect cube
Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2

1/5(2x+92)=5x find x
Answer:
x = 4
Step-by-step explanation:
[tex]\dfrac{1}{5}*(2x + 92) = 5x[/tex]
Multiply the equation by 5
[tex]5* \dfrac{1}{5}*(2x +92) =5x*5\\\\ 2x + 92 = 25x[/tex]
Subtract 2x from both sides
92 = 25x - 2x
92 = 23x
Divide both sides by 23
92/23 = 23x/23

After a dilating a square with a scale factor of 3, which describes the image of the square?
O Its sides are 1/3 as long as those of the original square.
O its sides are 3 times as long as those of the original square.
O Its sides are 3 units longer than those of the original square.
O Its sides are 3 units shorter than those of the original square.
Answer:
2. It's sides are 3 times as long as those of the origanal square.
Step-by-step explanation:
The scale factor is 3. So the scale of the sides of the orig. square to the image is 1:3. So, it is 3 times as large as the preimage.

At the city museum, child admission is $5.10 and adult admission is $9.60. On Monday, twice as many adult tickets as child tickets were sold, for a total sales of $558.90. How many child tickets were sold that day?
Answer:
23
Step-by-step explanation:
The amount of children's tickets is x, while the amount of adults' tickets is 2x
5.1*x- the amount of money from children
9.6*2x= 19.2x- the amount of money from adults
5.1x+19.2x= 558.9
x=23 - child tickets

this is my brothers math homework can someone help w the what is the meaning question
The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.
Both concepts are fundamental in arithmetic and algebraic calculations.
In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:
1. **Unknown Factor:**
- An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.
- In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.
- For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."
2. **Quotients:**
- "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.
- In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).
- For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.
- Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.
