what is x in this problem (2x-2)/x-3=5/6
Answer:
x = -3/7
Step-by-step explanation:
(2x-2)/x-3 = 5/6
(2x-2)×6 = 5×(x-3)
12x-12 = 5x-15
12x-5x = -15+12
7x = -3
x = -3/7
Final answer x is equal to -3/7.
Are 2x + 5 = 9 and -2x = 4 equivalent to each other
There are not equivalent to each other because the equation 2x+5=9 is equivalent to 2x=4
Answer: no.
Step-by-step explanation: 2x + 5 = 9 so subtract 5 from each side you get 2x = 4
X= 2
If we substitute that back in 2(2) + 5 = 9 so
If you do -2(2) = 4 it’s -4=4 and it’s not equivalent to each other

The paperweight is shaped like a square pyramid. The volume of the pyramid is 48 in. If the area of the base is 36 in?, what is the height of the pyramid?
Given:
Volume of a square base pyramid = 48 cubic inches.
Area of base = 36 sq. inches.
To find:
The height of the pyramid.
Solution:
Volume of a pyramid is
[tex]V=\dfrac{1}{3}Bh[/tex]
Where, B is the base area and h is the height of the pyramid.
Putting V=48 and B=36, we get
[tex]48=\dfrac{1}{3}(36)h[/tex]
[tex]48=12h[/tex]
[tex]\dfrac{48}{12}=h[/tex]
[tex]4=h[/tex]
Therefore, the height of the pyramid is 4 inches.

Answer:
x = (8√3)/3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = x
Side length adjacent to reference angle = 4
Apply CAH, thus:
Cos 30 = Adj/Hyp
Cos 30 = 4/x
x × Cos 30 = 4
x = 4/Cos 30
x = 4/(√3/2) (cos 30 = √3/2)
x = 4 × 2/√3
x = 8/√3
Rationalize
x = (8 × √3)/(√3 × √3)
x = (8√3)/3

(15 points!!) Valerie is making fruit salad using strawberries and melons. The ratio of strawberries to melons is 3:4. If Valerie makes 14 cups of fruit for a party, how many cups of strawberries does she use?
The ratio shows how many times one value is contained in another value.
The number of cups of strawberries Valerie used is 6 cups.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of strawberries to melons is 3:4.
Let us consider,
Strawberries = 3x
Melons = 4x
Now,
A total of 14 cups of fruit were made.
This means,
14 = 3x + 4x
14 = 7x
x = 2
Now,
The number of cups of strawberries is 3x.
3x = 3 x 2 = 6 cups
The number of cups of melons is 4x.
4x = 4 x 2 = 8 cups.
We see that,
6 cups + 8 cups = 14 cups.
Thus,
The number of cups of strawberries Valerie used is 6 cups.

Answer:
4, 16
Step-by-step explanation:
[tex] a_n = 3a_{n - 2} - a_{n - 1} - 1 [/tex]
Let's see if it works for a_3:
[tex] a_3 = 3a_{1} - a_{2} - 1 [/tex]
[tex] a_3 = 3(3) - (4) - 1 [/tex]
[tex] a_3 = 4 [/tex]
Yes, it works for a_3.
Now let's calculate a_4.
[tex] a_4 = 3a_{2} - a_{3} - 1 [/tex]
[tex] a_4 = 3(4) - (4) - 1 [/tex]
[tex] a_4 = 7 [/tex]
a_4 is also correct.
Let's calculate a_5.
[tex] a_5 = 3a_{3} - a_{4} - 1 [/tex]
[tex] a_5 = 3(4) - 7 - 1 [/tex]
[tex] a_5 = 4 [/tex]
Let's calculate a_6.
[tex] a_6 = 3a_{4} - a_{5} - 1 [/tex]
[tex] a_6 = 3(7) - 4 - 1 [/tex]

Answer:
half
Step-by-step explanation:
I got this answer by doing (22/7-2/3) and (22/7-2/3)/2 and comparing the results.
(22/7-2/3) = 52/21, which is about 2.47.
(22/7 - 2/3)/2 = 26/21, which is about 1.23.
With this, you can conclude that it would be half the value.

Triangle X has m2A = 30°, mZB = 90°, and m2C = 60° with side lengths of AB = 3, BC = 4, AC = 5.
Triangle Y has m2A = 30°, mZB = 90°, and mZC = 60' with side lengths of AB = 9, BC = 12, AC = 15.
Which statement best describes the relationship between these two triangles?
O They are similar triangles.
O They are similar and congruent triangles.
O They are congruent triangles.
O They are congruent but not similar triangles.
Answer:
O They are similar triangles.
Step-by-step explanation:
Given
Triangle X
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Triangle Y
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 9,\ BC = 12,\ AC = 15.[/tex]
Required
The relationship between X and Y
From the given parameters, the corresponding angles of both triangles are equal i.e.
A = A, B = B and C = C
However, the side lengths are not equal.
The side lengths of Y is 3 multiplied by the side lengths of X.
This is shown below:
Triangle X
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Multiply by 2 to get Triangle Y
[tex]AB= 3 * 3 = 9[/tex]
[tex]BC= 4 * 3 = 12[/tex]
[tex]AC = 5 * 3 = 15[/tex]
Since side lengths are not equal, but they have a common ratio of 3, then the triangles are similar.

Explain how to find the surface area of rectangular prisms and cubes. What formulas can you use?
Answer:
surface area of rectangular prisms A=2(wl+hl+hw)
surface area of cubes A=[tex]6a^{2}[/tex]
Step-by-step explanation:
Answer:
The total surface area of a rectangular prism or cube is equal to the sum of the areas of each side.
The area of each side is equal to its length multiplied by its width or A = L x W.
Since the areas of opposite sides are equal, multiple each side area by 2 to obtain the areas of opposite sides.
where:
L = length
W = width
H = height
total area = (2)(L)(W) + (2)(L)(H) + (2)(W)(H)
or simplified:
total area = 2[(L)(W) + (L)(H) + (W)(H)]
