simplify –4b + 8c + 12 – 8b – 2c + 6
Answers
Answer:
[tex]-12b + 6c + 18[/tex]
Step-by-step explanation:
The key to answering this question is combining like terms. Add or subtract the terms that have the same variable.
1) Let's start with finding all the terms that have a b and combine them - those terms would be -4b and -8b. Add their coefficients (the numbers in front of the variable).
[tex]-4b + 8c + 12 - 8b - 2c + 6 \\= -12b + 8c + 12 - 2c + 6 \\[/tex]
2) Next, let's do the same with all the terms that have a c. In this case, those terms would be 8c and -2c. So, add their coefficients too:
[tex]-12b + 8c + 12 - 2c + 6 \\\\= -12b + 6c + 12 + 6[/tex]
2) Finally, combine the constants (the terms with no variables). Those numbers would be 12 and 6.
[tex]-12b + 6c + 12 + 6\\= -12b + 6c + 18[/tex]
Thus, the answer is [tex]-12b + 6c + 18[/tex].
A school ordered 3 large boxes of board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. How many markers were originally in the box?
Answers
Step-by-step explanation:
Initially, the school had 3 boxes of board markers, and each box had X board markers, where X is the number we want to find.
Then the initial number of board markers is 3*X.
We know that after giving 15 markers to 3 teachers, we have other 90 markers left. This can be written as:
total markers = markers for the teachers + markers left
3*X = 15*3 + 90 = 45 + 90 = 135
now, we divide both sides by 3.
X = 135/3 = 45
From this, we know that in each box we have 45 markers
What is the final elevation if

?/1
What is the final elevation if
A whale starts at -9 m and changes 11 m?
?/1
What is the final elevation if
A fish starts at -9 meters and changes -11 meters?
Answers
Answer: Final elevation of butterfly = 4m
Final elevation for diver = -11m
Final elevation for whale= 2m
Final elevation for fish = -20m
Step-by-step explanation:
Final elevation= Initial poistion + Change.
A butterfly starts at 20 m and changes -16 m.
Final elevation = 20m +(-16m)
= 20-16 m [(-)(+)=(-)]
= 4m
A diver starts at 5 m and changes -16 m.
Final elevation = 5m + (-16) m
= 5m- 16 m [(-)(+)=(-)]
= -11 m
A whale starts at -9 m and changes 11 m.
Final elevation = (-9m)+11m
= 11m- 9m [-a+b=b-a]
= 2m
A fish starts at -9 meters and changes -11 meters
Final elevation = -9+(-11) m
= (-9-11) m [(-)(+)=(-)]
=-(9+11) m [-a-b=-(a+b)]
=-20m
Hence, Final elevation of butterfly = 4m
Final elevation for diver = -11m
Final elevation for whale= 2m
Final elevation for fish = -20m

In a group of 120 band students 30 of them play a woodwind instrument. What percent of the band students do not NOT play a woodwind instrument.
Answers
Answer: 75%
Step-by-step explanation:
We are told that in a group of 120 band students 30 of them play a woodwind instrument. The number of those that don't play woodwind instrument would be:
= 120 - 30 = 90
The percent of the band students that do not not play a woodwind instrument will be:
= 90/120 × 100
= 3/4 × 100
= 75%

You have $142.26 in a bank account. The bank requires you to have at least $30 in your account or else you are charged a fee. Write and solve an inequality that represents the amount you can write your next check for without being charged a fee.
Answers
Answer:
$142.26 - x ≥ $30
x ≤ $112.26
Step-by-step explanation:
Let the amount you can write on your next check without being charged a fee be x.
Given that you are to have at least $30 in your account or else you are charged a fee then
$142.26 - x ≥ $30
To solve, collect like terms
-x ≥ $30 - $142.26
-x ≥ -$112.26
x ≤ $112.26
Note that on dividing both sides by -1, the sign changes from greater than to less than.
