Answer:
6
Step-by-step explanation:
192=8*4*w
make w subject to formula
w=192/32
w=6
The expression of width is w = V/(l*h) and the value of width is 6.
What is substitution of equation to find the expression of width ?Given formula of volume is V = l * w * h .
Substituting width (w) from the above equation,
w = V/(l*h) .
Finding the value of width from the expression -Given expression after substitution is w = V/(l*h) .
⇒ w = 192/(8 * 4)
∴ w = 6 .
Thus the value of width is 6.
Therefore, the expression of width is w = V/(l*h) and the value of width is 6.

Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units. Triangle A B C is shown. Point D is the midpoint of side A B and point E is the midpoint of side B C. The lengths of A D and D B are 3 t, the lengths of B E and E C are 4 t, and the length of A C is 7 t + 6. What is the value of t
9514 1404 393
Answer:
t = 2 units
Step-by-step explanation:
The perimeter is the sum of the side lengths:
AD +DB +BE +EC +AC = 48 = 3t +3t +4t +4t +7t +6
42 = 21t . . . . . . subtract 6 and simplify
42/21 = t = 2 . . . . . . divide by the coefficient of t
A rectangles length is 6 units greater than its width. Write an equation expressing the rectangles area, A, as a function of W
Answer:
A = W² + 6W
Step-by-step explanation:
The width is W.
The length is 6 units greater than the width, so the length is W + 6.
The area is the product of the length and width.
A = (W + 6)W
A = W² + 6W

write and solve an equation to find the value of X. please explain in details and show your work!
The answer is x=34 degrees.
The answer you are looking for is x=34.
Solution/Explanation:
First things first, we need to understand that the sum of the angles of a triangle is 180°. We can apply this fact for the problem.
So, that means that the sum of all of the angles of this triangle is 180°.
So, therefore, we can formulate an equation:
2x+20+2x-10+x=180.
So, we now have our expression.
Now, all we need to do is simplify it.
Combining similar-like terms,
2x+2x+x+20-10=180.
Simplifying it now,
5x+10=180.
Subtracting 10 from both sides of the equation,
5x+10-10=180-10.
5x=170.
Finally, dividing both sides by 5,
5x/5=170/5.
x=34.
So, therefore the final answer is x=34.

What is the equation of the line that passes through (0, 3) and (7, 0)?
A. (Image 093047)
B. (Image 093055)
C. (Image 093108)
D. (Image 093116)
Answer:
[tex]y = -\frac{3}{7}x + 3[/tex]
Step-by-step explanation:
In order to find the equation of a line, we need to first find the slope. Slope is represented by the formula:
[tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]
where (x1, y1) and (x2, y2) are point on the line. In this case, we can use the points (0, 3) and (7, 0):
[tex]\frac{0-3}{7-0} = -\frac{3}{7}[/tex]
The point (0, 3) is the y-intercept, so given an equation in the form y = mx + b, 3 would be b and we already calculated the slope, which is m. We can plug these values in to get:
[tex]y = -\frac{3}{7}x + 3[/tex]

you are solving an equation with a variable on each side. does the side on which you choose to isolate the variable affect the solution? why might you choose one side over the other?
Answer:
Does the side on which you choose to isolate the variable affect the solution?
No, because at the end you get an equation with a variable on one side only.Why might you choose one side over the other?
To simplify or minimize the number of operations you need. Moving part of the terms from one side to another adds at least one extra operation and it may also bring some complications.35 POINTS, i dont understand this question!!!! can someone give me a brief yet useful explanation??
The music store sold 12 trumpets and 19 clarinets last month.
a) Write an equation to show the amount of money earned on trumpet and clarinet sales last month. Define your variables.
b) If clarinets sell for $139.95 and the store made $4578.45 from sales on the two instruments, find the price of a trumpet.
Answer:
a) let x = price of 1 trumpet
let y = price of 1 clarinet
12x + 19y
b)
12x + 19(139.95) = 4578.45
12x + 2659.05 = 4578.45
12x = 1919.4
x = $159.95
a sports team won twice as many games as they lost. the sum of games won and games lost was 42. How many games did they win?
Answer:
The number of win games are 28
Step-by-step explanation:
x=lost. 2x=win
2x+x=42
3x=42
x=42
3
x=14
win=2x
=2×14
=28
The number of games the sports team won if a sports team won twice as many games as they lost is 28games
Let the amount the sports team lost be x
If the sports team won twice as many games as they lost, then the number of games won will be 2x
If the sum of games won and games lost was 42, then:
x + 2x = 42
3x = 42
Divide both sodes by 3
3x/3 = 42/3
x = 14
Amount of games won = 2(14)
Amount of games won = 28games
Hence the amount of games the sports team won is 28games
