How do I show the work for this
Answers
Answer:
hope that helps :))
Step-by-step explanation:
Step 1: Subtract 12c from both sides.
12c+12−12c=12c+9−12c
12=9
Step 2: Subtract 12 from both sides.
12−12=9−12
0=−3

For some reason, in our history class, there are 14 more boys than there are girls. If a total 32 students are in the class, how many boys and how many girls are there
Answers
Answer:
We can assume X is the number of girl, so the number of boy should be X+6.
Based on question, we can get X+X+6=32
2X+6=32
2X=26
X=13
So the answer is, 13 girls are in the class.

If the function f(x)= 2x – 3 and g(x) = 3/2x + 1 then which of the following is a true statement?
f(0) > g(0)
f(8) = g(8)
f(2) = g(2)
g(4) < f(4)
Answers
Answer:
f(8) = g(8)Step-by-step explanation:
Given
f(x)= 2x – 3 and g(x) = 3/2x + 1
f(0)= 2(0)-3
f(0) = -3
g(0) = 3/2(0)+1
g(0) = 0+1
g(0) = 1
Hence since -3 < 1, this means that f(0)<g(0)
Also;
f(8)= 2(8)-3
f(8) = 16-3
f(8) = 13
g(8) = 3/2(8)+1
g(8) =12+1
g(8) = 13
This shows that g(8) = g(8)
Hence g(8) = g(8) is a true statement
A class is playing a game called “Guess my Number,” in which the number is an integer. The teacher gives these clues for the unknown number.
4 + h ≤ 7 and h + 1 > 3
What is the value of the unknown number, h?
Answers
Answer:
h=3
Step-by-step explanation:
you want h alone on one side of the equation and you must do the same to both sides, 4-4 cancels out the 4, 7-4=3 so h is greater than or equal to 3, next, 1-1 cancels out 1, 3-1=2 so h>2, therefore h=3

h = 3

An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle
Answers
Sum of two angles that are supplementary = 180°
Let the first angle be x .
Then the other angle = x + 40
Measure of each angle =
[tex]x + x + 40 = 180[/tex]
[tex]2x + 40 = 180[/tex]
[tex]2x = 180 - 40[/tex]
[tex]2x = 140°[/tex]
[tex]x = \frac{140}{2} [/tex]
[tex]x = 70°[/tex]
Which means :-
The first angle:-
[tex]= x = 70°[/tex]
The second angle :-
[tex]x + 40[/tex]
[tex]70 + 40[/tex]
[tex] = 110°[/tex]
Therefore , the two supplementary angles are 70° and 110° .

x < -8, third from top option in the picture.
Step-by-step explanation:
5(2x - 4) < -100
10x - 20 < -100
10x < -80
x < -8
Answer:
3rd option from the top (open circle arrow going left)
Step-by-step explanation:
5(2x-4) is less than - 100
5 times 2x is 10x and 5 times - 4 is - 20 so,
10x - 20 is less than - 100
now do inverse operations to isolate x, add 20
- 20 plus 20 is 0 and -100 plus 20 is - 80
10x is less than -80
divide both sides by 10 and you get,
x is less than - 8

How much would it cost to make 25 shirts?
$ Answer
How much would students earn if they sold 25 shirts?
$ Answer
Will students make more money than they spent if they make and sell exactly 25 shirts?
Answers
Answer:
The answer is below
Step-by-step explanation:
The total cost for producing x number of shirts = 100 + 7x
The price of each shirt is $15, therefore:
Revenue = price per shirt × number of shirts = 15 × x = 15x
Revenue = 15x
The cost of making 25 shirts is given as:
Cost = 100 + 7x = 100 + 7(25) = $275
The money earned from producing 25 shirts is given as:
Revenue = 15x = 15(25) = $375
Since the revenue is greater than cost, the students would make more money than they spent if they make and sell exactly 25 shirts
