Answer:
138/18
23:3
Step-by-step explanation:
There are 18 empty seats so we can already fill out the right side of our ratio (yes I said our. Oh the communism!) with 18, to make :18.
We also know that there are 156 seats, so we will subtract 18 to find the amount of the filled seats, which is 156-18 = 138
138 seats are filled.
We can put the 138 on the left side of the ratio which is now
138:18
We now divide both sides by 2 to try to get the simplified form.
138/2 = 69
18/2 = 9
69:9
Now we divide both sides by 3.
69/3 = 23
9/3 = 3
23:3
23 and 3 are both prime numbers meaning that there are no factors to divide or simplify with anymore except for the same number and 1.
The answer is 23:3

Aaliyah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $66 for parts. The total was $441. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Equation:
Answer: x =
Answer:
x=125
Step-by-step explanation:
First identify what the varible means,
x = the cost of the labor per hour.
Next, write out an equation
3x + 66 = 441
Solve,
3x+66=441
Step 1: Subtract 66 from both sides.
3x+66−66=441−66
3x=375
Step 2: Divide both sides by 3.
3x/3 = 375/3
x=125

area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh
Answer:
8m
Step-by-step explanation:
We can convert the trapezium into a rectangle to make finding the area easier.
Say that the top side is 9m, and that the bottom side is 12m.
12 - 9 = 3
3/2* = 1.5
*Note that we are dividing by two to get the "overhang" of the bottom side.
Now that we have our overhang, we can find the length of the "t-rect"**.
**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.
12 - 1.5 = 10.5
9 + 1.5 = 10.5
The length of the t-rect is 10.5.
84/10.5 = 8
The height of the t-rect is 8m.
Since the height of the original trapezium is equal to the height of the t-rect***,
***Since we have only adjusted the length
this also means that 8m would also be the height of the original trapezium.
Now, there is a second way of doing this.
Find the median of 12 and 9.
9, 10, 11, 12
10, 11
The median is 10.5.
84/10.5 = 8
You get the same answer. These methods could be used as a solve-then-check method to another problem like these.
Hope this helps. Have a nice day.

Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?
Question:
Three students were working on 630,000÷700 in math class.
a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.
Determine which student found the correct quotient.
b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?
Answer:
a. Micah is correct
b.
[tex]Expression = 63000 \div 700[/tex]
[tex]Expression = 630000 \div 7000[/tex]
Step-by-step explanation:
Given
[tex]Expression = 630000 \div 700[/tex]
[tex]Desiree = 9000[/tex]
[tex]Micah = 900[/tex]
Solving (a): Who is correct?
To do this, we first calculate the quotient of the expression.
[tex]Expression = 630000 \div 700[/tex]
Divide 630000 by 700
[tex]Quotient = 900[/tex]
Hence:
Micah is correct
Solving (b): What Delilah must have copied?
We have:
[tex]Delilah = 90[/tex]
There are no options to pick from. So, we just need to work out expressions that equals 0.
Possible expressions are:
[tex]Expression = 63000 \div 700[/tex]
[tex]Expression = 630000 \div 7000[/tex]
