Which one of these are not equivalent to each other and which ones are:
3 (x+2), 3x+6, 3 (2x)
Answer:
3(x+2) and 3x+6 are equivalent.
3(2x) is not.
Step-by-step explanation:
Simplify the expressions first.
1. 3(x+2) becomes 3x+6
2. 3x + 6
3. 3(2x) becomes 6x
The first and second are equivalent to each other.
The third one is not equivalent.

Shaun and trudy are selling raffle tickets. So far shaun has sold x tickets. Trudy has sold 3 more tickets than half the number of tickets that shaun sold.what expression represents the number of raffle tickets that shaun and trudy have sold altogether?
Answer:
x/2 + 3
Step-by-step explanation:
Shaun sold x tickets.
Trudy has sold 3 more tickets than half the number of tickets that Shaun sold.
Half the number Shaun sold is x/2.
3 more than that is x/2 + 3
Answer: x/2 + 3
Answer:
x/2 +3 + x
Step-by-step explanation:
Trudy sold x/2 + 3 tickets compared to shaun. So the total number of tickets they sold overall is x/2 +3 + x.
Mr. Chang’s class has 28 students, 4/7 of whom are girls. Which equation shows how to determine the number of girls in Mr. Chang’s class?
A. 28 ÷ 4/7 = 49
B. 28 x 4/7 = 16
C. 4/7 ÷ 28 = 1/49
D. 7/4 ÷ 28 = 1/16
Answer:
b

Convert 9 3/4 to an improper fraction.
Answer:
39/4
Step-by-step explanation:
Because I multiplied 4 x 9 + 3
9 3/4 may be expressed as an improper fraction as 39/4 or 9.75.
What is Fraction?
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.
9¾ is a mixed fraction. 9 is the whole number whereas ¾ is the fractional part. 9¾ is also 9+¾.
Fractions that have a numerator greater than a denominator, such as 8/7 or 123/112, are considered improper fractions.
Thus, to convert 9 3/4 into an improper fraction, multiply the whole number component—in this case, 9, by the denominator (4 in this case). The multiple of 9 and 4 you just discovered is added to the numerator (3), which is then used as the numerator. The numerator (four) stays the same.
Therefore, 9 3/4 can be written as 39/4 or 9.75 in the terms of the improper fraction.

Answer:
Answer is after 20 miles
Step-by-step explanation:
10 +2.5x = 3x
10 = 3x-2.5x
10=0.5x
10/.5=x
x=20
At 20 miles they both have a cost of 60
Let's see what to do buddy....
____________________________
Step (1)
Express taxi charges 2.50 $ per mile.
So if each mile equals x the taxi charges 2.50 x.
There's the starting fare too.
So ;
Express taxi charges by the following function :
[tex]f(x) = 2.5x + 10[/tex]
____________________________
Step (2)
Speedy taxi charges 3 $ per mile.
So if each mile equals x the taxi charges 3x .
There's no starting fare.
So ;
Speedy taxi charges by the following function :
[tex]g(x) = 3x[/tex]
____________________________
Step (3)
To find that after how many miles is the cost of both taxi services the same , we must equal their functions.
Then solve for x .
So we have :
[tex]f(x) = g(x)[/tex]
[tex]2.5x + 10 = 3x[/tex]
Subtract the sides of the equation minus 2.5x :
[tex]10 = 0.5x[/tex]
[tex]10 = \frac{1}{2}x \\ [/tex]
Multiply the sides of the equation by 2 :
[tex]x = 20[/tex]
So after 20 miles both taxi services have the same cost.

And we're done.

1. In ABC, A=45 degrees, B=75 degrees, and BC=12. What is the length of AB?
We know that sum of the interior angles of any triangle equal 180° :
So :
A + B + C = 180°
45° + 75° + C = 180°
120° + C = 180°
Both sides minus ( 120°) :
C = 180° - 120°
C = 60°
_________________________________
According to the theorem of sinuses :
[tex] \frac{AB}{ \sin(C) } = \frac{BC}{ \sin(A) } \\ [/tex]
[tex] \frac{AB}{ \sin(60) } = \frac{12}{ \sin(45) } \\ [/tex]
[tex] \frac{AB}{ \frac{ \sqrt{3} }{2} } = \frac{12}{ \frac{ \sqrt{2} }{2} } \\ [/tex]
[tex]Multiply \: both \: sides \: by \: \frac{ \sqrt{3} }{2} [/tex]
[tex] AB = \frac{24}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} \\ [/tex]
[tex]AB = \frac{12 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{2 \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ ({ \sqrt{2} })^{2} \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ \sqrt{2} \times \sqrt{2} \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ \sqrt{2} \times 6 \sqrt{3} }{1} \\ [/tex]
[tex]AB = \sqrt{2} \times 6 \sqrt{3} [/tex]
[tex]AB = 6 \sqrt{2 \times 3} [/tex]
[tex]AB = 6 \sqrt{6} [/tex]

What is the area of a triangle if the top is 3 the left side is 6 and the right side is 6.7
the answer is 120.6 I'm pretty sure
Answer:
9.525 units squared
Step-by-step explanation:
I'm assuming the 3 is the base of the triangle so I split 3 in half and got 1.5 for 2 right triangles. I then did the area of a right triangle formula 1/2 base x height
1/2(1.5 x 6)=4.5
1/2(1.5 x 6.7) =5.025
Add these two together
5.025+4.5=9.525
9.525units squared

To win a trivia game, Nathan must score at least 105 points. Each correct answer is worth \large 3\frac{1}{3} points, and each incorrect answer is worth \large -\frac{1}{2} . If he gets 33 questions correct and 20 questions incorrect, how many points does he have? Does he win? (yes or no)
Answer:
Nathan earned 100 points. he lost the trivia game by 5 points.
Step-by-step explanation
3[tex]\frac{1}{3}[/tex] * 33 = 110 points earned
[tex]\frac{1}{2}[/tex] * 20 = 10 points lost
110-10 = 100

You notice a hot air balloon descending. The elevation h
(in feet) of the balloon is modeled by the function h(x)=−8x+360,
where x
is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
Answer:
the domain is 0 x 45 and the range is 0 h 360. The slope is -8, so the change in the height of the ballon is -8 feet per second. The h-intercept is 360, so the height of the ballon when the first noticed it was 360 feet. The x-intercept is 45, so the time it took the hot air balloon to reach the ground was 45 seconds.
Step-by-step explanation:
The descending balloon is an illustration of a linear function.
The balloon spent 45 seconds in air The balloon was at a height of 360 feet when you noticed it.The balloon descends 8 feet per seconds.[tex]\mathbf{Domain=[0,45]}[/tex].[tex]\mathbf{Range=[0,360]}[/tex]The function is given as:
[tex]\mathbf{h(x) = -8x + 360}[/tex]
See attachment for the graph of h(x)
From the graph, we have the following observations
The y value ranges from 0 to 360The x value ranges from 0 to 45The function crosses the graph at x = 45 and y = 350The above highlights mean that:
[tex]\mathbf{Domain=[0,45]}[/tex][tex]\mathbf{Range=[0,360]}[/tex][tex]\mathbf{x-intercept = 45}[/tex][tex]\mathbf{y-intercept = 360}[/tex]The x intercept means that:
The balloon spent 45 seconds in air
The y-intercept means that:
The balloon was at a height of 360 feet when you noticed it.
A linear function is represented as:
[tex]\mathbf{y = mx + c}[/tex]
Where:
m represents the slope
By comparison with [tex]\mathbf{h(x) = -8x + 360}[/tex]
[tex]\mathbf{m = -8}[/tex]
The above value of slope means that:
The balloon descends 8 feet per seconds
