Answer:
3/2
Step-by-step explanation:
Let x be the unknown number.
If twice a number added to 3: 2x+3
is divided by the number plus 3: (2x+3)/3
the result is three halves: (2x+3)/3 = 3/2
(2x+3)/3 = 3/2
Multiply both sides by 3:
2x + 3 = 9/2
Subtract 3 from both sides:
2x = 9/2 - 3 = 9/2 - 6/2 = 3/2
Divide both sides by 2:
x = 3/4
Check:
(2x+3)/3 = 3/2
(2*(3/4)+3)/3 = 3/2
(6/4 + 3)/3 = 3/2
(18/4)/3 = 3/2
6/4 = 3/2
3/2 = 3/2
Check!

Consider the graph of f shown be
Estimate the average rate of change from X = 2 to x = 5.
Answer:
Average rate of change = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
We have to calculate the average rate of change of the graph at x = 2 to x = 5.
From the graph attached,
At x = 2,
f(2) = 3
At x = 5,
f(5) = 7
Since, average rate of change of the function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]
Therefore, average rate of change of the function represented by the graph will be = [tex]\frac{7-3}{5-2}[/tex]
= [tex]\frac{4}{3}[/tex]

Cookie Monster bought four packs of chocolate cookies and three packs of butter cookies for $17. Two packs of
butter cookies cost $6. All chocolate cookies cost the same and all butter cookies cost the same. What is the ratio of
the cost of a pack of chocolate cookies to the cost of a pack of butter cookies?
2:3
6 ÷ 2 = $3 (cost of 1 pack of butter cookies)
3 x 3 = 9 (cost of 3 packs of butter cookies)
17 - 9 = 8 (cost of 4 packs of chocolate cookies)
8 ÷ 4 = 2 (cost of one pack of chocolate cookies)

3) 15 +b=23
I need help pls I don’t get it
Answer:
b=8
Step-by-step explanation:
15 +b=23
get b by itself by subtracting 15 on both sides
b=8
the answer is
= 8
you need to Subtract 15 from both sides of the equation
+ 15 = 23 + 15 − 15 = 23 − 15
simplify
and then you get your answer

3/2 ∜(2(x-6)^3 )+4=16
Answer:
x ≈ 18.7
Step-by-step explanation:
This is a big equation, so let's break it down a bit.
[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3 )} +4=16[/tex]
Let's start by isolating the radical which is x.
So subtract 4 from both sides :
[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3)}[/tex][tex]=12[/tex]
Now multiply both sides by 2 to get rid of the fraction :
[tex]3\sqrt[4]{(2(x-6)^3)} = 24[/tex]
Now divide both sides by 3 to get rid of the number out of the poly root :
[tex]\sqrt[4]{2(x-6) ^3}[/tex][tex]=8[/tex]
Now take both sides of the equation to the power of 4 :
[tex]2x^3 - 36x^2+216x-432=4096[/tex]
And lastly, solve :
[tex]x = 18.69920[/tex] which is rounded up to [tex]x[/tex] ≈ [tex]18.7[/tex]

The bases of the two similar triangular prisms shown below are equilateral triangles.
What is the value of x, an edge length of the larger prism in centimeters?
9514 1404 393
Answer:
28 cm
Step-by-step explanation:
For the similar figures, a proportion can relate the side lengths.
x/(7 cm) = 11.2/2.8
x = (7cm)(11.2/2.8) = 28 cm
The value of x is 28 cm.

Write the equation of the line in slope intercept form equation of the line in slope intercept form is blank
Answer:
y=70x+20
Step-by-step explanation:
Okay so the slope is determined by having two points on the line in this case one of them is (0,20) and (2,160), you're going 140 up and 2 over so the slope would be [tex]\frac{140}{2}[/tex] which equals 70 so thats how you get m, to get b you simply put the y interecept which is at 20.
Plugs those numbers together you get y=70x+20 which is intercept form.
The distance from the origin to the point (-27,36)
The distance from the origin to the point (-27,36) is 45
We are going to make use of Pythagorean Theorem to determine the length of the hypotenuse of the right triangle:
Hence;
(0,0) to (-27,0)
(-27,0) to (-27,36)
Using this formula
c2 = a^2 + b^2
Let plug in the formula
c2 = (-27)^2 + (36)^2
c2=-729+1296
c2 = √2025
c = 45
Inconclusion The distance from the origin to the point (-27,36) is 45.
