Answer:
B. 42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
42 + 2n ≥ 80
Subtract 42 from both sides
2n ≥ 38
Divide both sides by 2
n ≥ 19

Answer:
42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
If she wants to make at least $80 the she would need to sell a number of cedis in addition to her $42
That is:
Let n be the number of CDs
42 + 2n
and to get at least $80, (at least meaning $80 dollars or more)
So that will be:
42 + 2n ≥ 80
So to get at least 80 dollars, she'll have to sell 19 CDs
Why 19 CDs? 42 + 2n which is 42 + 2(19) = 80
Which is why 42 + 2n ≥ 80, so n ≥ 19

Write an inequality to determine when Apartment A will cost more than Aparment B: Johnny is searching for an apartment and has narrowed it down to two choices. Apartment A has a $300 security deposit and costs $800 each month. Apartment B has a $900 deposit and costs $500 each month.
Answer:
Apartment A will cost more than Aparment B after 2 months which means from the third month and above, Apartment A will cost more than Aparment B
Step-by-step explanation:
Write
Let the number of months be represented as y
Apartment A has a $300 security deposit and costs $800 each month.
$300 + $800 × y
300 + 800y
Apartment B has a $900 deposit and costs $500 each month
$900 + $500 × y
900 + 500y
An inequality to determine when Apartment A will cost more than Aparment B :
Apartment A > Apartment B
300 + 800y > 900 + 500y
300 + 800y = 900 + 500y
Collect like terms
800y - 500y = 900 - 300
300y = 600
y = 600/300
y = 2 months
Therefore Apartment A will cost more than Aparment B after 2 months which means from the third month and above, Apartment A will cost more than Aparment B
There were 54 students in the school choir for a concert the music teacher arranged the students in six rows with the same number of students in each row the choir saying seven songs at the concert which of these shows how many students were in each row math question
Answer:
9 students in each row
Step-by-step explanation:
Given : 54 students, arranged in 6 rows (with equal students), singing 7 songs.
No of students in one row x No of rows = Total students
So, No of students in one row = Total students / No of rows
No of students in each row = 54 / 6 = 9

A washing machine is filling up with water at a constant rate. The rate is 3/4 of a gallon in 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute. what did he do wrong?
Answer: you have to see how many gallons fill the container per minute, so take 3/4 and divide it by 1/5, which gives 15/4. So he multiplied the two numbers instead of dividing.
Step-by-step explanation:
Answer:
[tex]\frac{15}{4}[/tex] gallon per minute
Step-by-step explanation:
Given parameters:
Quantity of gallon = [tex]\frac{3}{4}[/tex] gallon
Time taken = [tex]\frac{1}{5}[/tex] min
Unknown:
The solution is [tex]\frac{3}{20}[/tex] gallon per minute, what did he do wrong = ?
Solution:
To find the rate:
Rate = [tex]\frac{Quantity of gallon}{time }[/tex]
Input the parameters and solve
Rate = [tex]\frac{\frac{3}{4} }{\frac{1}{5} }[/tex] = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{5}[/tex]
Invert the [tex]\frac{1}{5}[/tex] to give 5
= [tex]\frac{3}{4}[/tex] x 5
= [tex]\frac{15}{4}[/tex] gallon per minute
The student failed to invert the [tex]\frac{1}{5}[/tex] before multiplying with [tex]\frac{3}{4}[/tex]

Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Answer:
6.3, 14.7
Step-by-step explanation:
10.5 tress for 5 cabins, using 10.5/5 (2.1) we can assume there is 2.1 trees per cabin.
3*2.1= 6.3
7*2.1=14.7
Answer:
the answers are 6.3 and 14.7. Put the 6.3 beside the 3 in the table and put the 14.7 beside the 7 or it'll be counted as incorrect.

At seven different restaurants, Rachel found that house salads cost an average of $3.80. If six of the restaurants priced house salads at $3.00, $3.45, $4.15, $4.60, $4.65, and $2.80, how much did a house salad cost at the other???????
Answer:
$3.77
Step-by-step explanation:
First, add all of the numbers together:
$3.00+$3.45+$4.15+$4.60+$4.65+$2.80=22.65
Next, divide that number by the number of numbers:
22.65/6=3.77

Hello, can someone answer this please?
What is 8,187 divided by 24 (not resulting in a decimal number)?
Answer:
8,187 divided by 24 is 341.125
Step-by-step explanation:
i hope this helps!
Answer:
The answer is 341.125.
But, if you want it without a decimal, you need to round.
You round up if the first number right of the decimal is over 5 or 5, and down if the first number to the right of the decimal is under 5.
Since the first number to the right of the decimal is 1, it is under 5.
So we round down.
So it would be 341.
The answer without a decimal is 341.
Hope this helps!

Is (0,1) , (1,3) , (2,5), (3,7) a function?
Answer:
Yes it is a function.
use you can try out the Vertical Line test which states that if your line intersects repeatedly it is not a function.
Every x-value is paired with a y-value. If the x-value is being paired with more than one y-value it does not pass the test.
All these values you had listed pass the vertical line test.

A rectangle has length 8*10^4 mm and width 4*10^4 mm. The rectangle's length is how many times its width?
Answer:2
Step-by-step explanation:
The ratio of rectangle length to width is 2 thus the length is 2 times the width.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = eg 2/3
Multiplication = eg 2 × 4
As per the given question,
Length of rectangle = 8 × 10⁴ mm.
Width of rectangle = 4× 10⁴ mm
The ratio of length to width
Length/width = (8× 10⁴)/(4× 10⁴)
Length/width = 2
Length = 2 × width
Hence "The ratio of rectangle length to width is 2 thus the length is 2 times the width".
