Explanation:
Let's check to see if 9/12 is the same as 16/24.
Set them equal to one another, and then use cross multiplication like so
9/12 = 16/24
9*24 = 12*16
216 = 192
Both sides aren't the same value after simplifying everything. The third equation being false leads to the first equation being false as well.
Therefore, 9/12 is not the same as 16/24. We can rule out choice A.
-----------------------
Let's check choice B
9/12 = 15/20
9*20 = 12*15
180 = 180
We have a match, so 9/12 is the same as 15/20
Notice how:
9/12 = 0.7515/20 = 0.75Both fractions lead to the same exact terminating decimal, which is more evidence that the two fractions are equivalent.
Choice B is the final answer.

x= 2 + ln(30)/ln(7)
decimal form
x= 3.74786969
Step-by-step explanation:
What I like to call the logarithmic equation solver.
Bring it down turn it around.
First bring down the 7 to a ㏒7 and the x-2 so that ㏒7(x-2)=30
Then change the constants from on another so then it would look like
㏒7(30)=x-2
solve for x
to solve do the log base finder equation ㏒(30)/ln(7)
and add 2
To accomplish this task you have to take the logarithm of both sides of the equation to remove the variable from the exponent.
ln(30)/ln(7)+2
ln(30)=3.401
ln(7)=1.946
3.401/1.946=1.7476
1.7476+2=3.748 after considering all extra decimal places to the closest thousandth.

a polygon has a interior angle 172
find the number of sides of this polygon
Answers
Answer:
45 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , that is
exterior angle + 172° = 180° ( subtract 172° from both sides )
exterior angle = 8°
The sum of the exterior angles of a polygon = 360°
To find the number of sides n , divide 360° by 8°
n = 360° ÷ 8° = 45
Answer:
45 sides
Step-by-step explanation:
If each of the interior angles is 172 degrees, then each of the exterior angles is 8 degrees. Since the sum of the exterior angles of any polygon is 360 degrees, there are 360 / 8 = 45 exterior angles and 45 sides

Which of the following equations is steeper?
y=-2x+1
y=-5/4x+7
y=x-1
y=5x-1
Answers
Answer:
Option 4: y = 5x - 1
Step-by-step explanation:
The slope, or rate of change, represents the ratio of the vertical change (in y) to the horizontal change (in x) of points along the line. Thus, the slope is a means of measuring the steepness of a given line.
Generally speaking, slopes with higher values tend to have steeper lines.
Compare the slopes:In comparing the slopes of the given options:
Option 1: slope = -2
Option 2: [tex]\LARGE\mathsf{slope = -\frac {5}{4}}[/tex] or 1.25
Option 3: slope = 1
Option 4: slope = 5
Option 4 has the highest slope of 5. Therefore, the graph of y = 5x - 1 has the steepest line.
Attached is the graphed equations to prove that the graph of the equation in Option 4 has the steepest line.
Find the value of x in each case
Answers
Answer:
Step-by-step explanation:
∠AEB + ∠FEC = 180 {linear pair}
∠AEB = 180 - 4x
DE // AB , AE is transversal,
∠EAB = ∠DEA {Alternate interior angles}
∠EAB = 2x
∠EBC = ∠AEB + ∠EAB {Exterior angle property}
6x = 180 - 4x + 2x
6x = 180 - 2x
Add 2x to both sides
6x + 2x = 180
8x = 180
x = 180/8
x = 22.5

PLEASE MARK ME AS BRAINLISTFind the 75th term of the arithmetic sequence -21, -10, 1
Answers
Answer:
793
Step-by-step explanation:
Arithmetic sequences are basically linear equations, so as input increase by one output always increases by the same amount. In sequences this is called common difference. To find it, just subtract one term by the term right before it.
So, -10--21=11 and also 1--10=11
so common difference is 11
now we will use the formula Asubn=Asub1+d(n-1)
D is Common difference and n is the term you're solving for. The n-1 is a result of the first term being in the formula. When one is plugged into n-1 you get zero and then multiply d by zero and you get zero and are left with Asub1
Anyways, Asub75=-21+11(75-1)=793
How do i find the slope-intercept form for 6x=8y+10
Answers
Answer:
y = 3/4x - 5/4
Step-by-step explanation:
6x=8y+10
Well you must first get your equation set up into the form called "Slope intercept."
6x=8y+10
Add 8y on both of your sides because your y is suppose to be alone.
8y + 6x = 10
Subtract 6x on both sides since it is in fact the opposite of addition.
8y = 6x + 10
Now, you will divide by 8 on both sides. When doing this your y will be alone.
y= 6/8x + 10/8
Note: You can leave it like this but you want to probably simplify.
y = 3/4x + 5/2
or
y = 3/4x - 5/4

Substance A has 2% alcohol mixture, and substance B has 6% alcohol mixture. To mix substance A and B for a capacity of 60 liters with 3.2% alcohol mixture, how many liters of substance A and B are used each?
Answers
Answer:
18 liters of 6% substance B
42 liters of 2% substance A
Step-by-step explanation:
let x be the liters of 6%, the balance of 60 - x liters is the 2% together they make 60 liters of 3.2%
6x + 2(60 - x) = 3.2(60)
distribute
6x + 120 - 2x = 192
Combine like terms
4x = 72
Divide bothsides by 4
x = 18 liters of 6%
60 - x = 42 liters of 2%

Answers
Answer:
34
Step-by-step explanation:
f(-3) = -3(-3) +7
f(-3) = 16
g(3) = -7(3) +3
g(3)= -18
16 -(-18) = 34
Answer:
34
Step-by-step explanation:
f(x) = -3x + 7
f(-3) = -3(-3) + 7
= 9 + 7 (two negatives make a positive)
= 16
g(x) = -7x + 3
g(3) = -7(3) + 3
= -21 + 3
= -18
16 - (-18)
16 + 18 (two negatives make a positive
= 34

What is the average rate of change of the function f(x)=4x^2+3x on the interval [1,5]
Answers
Answer:
7, though I don't know if it's 100% correct. I tried to help.
Step-by-step explanation:
f(x) = 4x^2 + 3x interval [1,5]
f(1) = 4(1)^2 + 3(1)
f(1) = 4 + 3
f(1) = 7
Answer:
[tex]\boxed {\boxed {\sf 27}}[/tex]
Step-by-step explanation:
The average rate of change is the change in the output from one input to another. Essentially, it is the change in y over the change in x.
[tex]\frac {\Delta y}{\Delta x} = \frac { f (x_2)- f(x_1) }{x_2-x_1}[/tex]
Let's assign 1 to x₁ and 5 to x₂.
[tex]\frac {f(5)-f(1)}{5-1}[/tex]
We must find the outputs f(5) and f(1). Substitute the value in for each x in the function.
f(x)= 4x² + 3x
f(5) = 4(5)² + 3(5) f(5)= 4(25) + 15 f(5) = 100 + 15 =115f(1)= 4(1)² + 3(1) f(1)= 4(1) + 3 f(1)= 4+ 3 =7
Now we can find the average rate of change. We know the outputs and we know the inputs.
[tex]\frac {f(5)-f(1)}{5-1}[/tex]
[tex]\frac {115 -7}{5-1}[/tex]
[tex]\frac {108}{4}[/tex]
[tex]27[/tex]
The average of change of the function f(x) = 4x² + 3x on the interval [1,5] is 27.
