what is the value of x in x(a+b)=b(c-x)
Answers
Answer:
x = [tex]\frac{bc}{a+2b}[/tex]
Step-by-step explanation:
x(a + b) = b(c - x) ← distribute parenthesis on both sides
ax + bx = bc - bx ( add bx to both sides )
ax + 2bx = bc ← factor out x from each term on the left side
x(a + 2b) = bc ← divide both sides by (a + 2b)
x = [tex]\frac{bc}{a+2b}[/tex]

The path of a race will be drawn on a coordinate grid like the one shown below. The starting point of the race will be at (−5.3, 1). The finishing point will be at (1, −5.3).
Part A: Use the grid to determine in which quadrants the starting point and the finishing point are located. Explain how you determined the locations. (6 points)
Part B: A checkpoint will be at (5.3, 1). In at least two sentences, describe the difference between the coordinates of the starting point and the checkpoint, and explain how the points are related. (4 points)
Answers
The Cartesian coordinate plane, specify locations by a pair of coordinates that indicate the magnitude in perpendicular, x, and y directions
The correct responses are;
Part A: The starting point is in the second quadrant and the finishing point is in the fourth quadrant.Part B: The starting point and the check point are on different quadrant. Both points are on the same horizontal line.Reasons:
The location of the start point of the race = (-5.3, 1)
Location of the finishing point = (1, -5.3)
Part A: The signs of the x and y-values in the quadrants are;
[tex]\begin{tabular}{|cc|c|}Quad II, x -ve, y +ve&&Quad I, x, and y are +ve\\&&\\Quad III, x -ve, y -ve&&Quad IV, x +ve, y -ve\end{array}\right][/tex]The coordinates of the starting point is (-5.3, 1), therefore, given that the x-
coordinate is negative and the y-coordinate is positive, the quadrant of the
starting point is quadrant II (the second quadrant).
The quadrant of the starting point is the second quadrant.The coordinates of the finishing point is (1, -5.3), the x-value is positive and
the y-value is negative, which indicates that the quadrant of the finishing
point is quadrant IV (the fourth quadrant).
The quadrant of the finishing point is the fourth quadrant.Part B: The location of the checkpoint is; (5.3, 1)
The difference is that the x-value of the checkpoint is positive while the x-value of the starting point is negative, and they are therefore on different quadrants.
The similarity is that, the magnitude of the x, and y values of the coordinates of the check point and the starting point are the same. Therefore, the checkpoint and the starting point are on the same horizontal line.

Write five other iterated integrals that are equal to the given iterated integral. 8 0 x2 0 y f(x, y, z) dz dy dx 0
Answers
An iterated integral is the outcome of taking integrals toward a function of more than one variable in such a way that part of the variables is treated as constants for each of the integrals.
From the given parameters, we are to write out five iterations for a triple integral;
[tex]\mathbf{\int ^8_0\ \int^{x^2}_{0} \ \int^y_0 \ \ f(x, y, z) \ dz dy dx }[/tex]
where;
the region is bounded by 0 ≤ z ≤ y, 0 ≤ y ≤ x², 0 ≤ x ≤ 8.Thus, since x, y, z are functions of at least one variable, we can have the following iterations:

−15x + 3 - 3 ≤ 7 - 3
−15x ≤ 4
−15x / -15 ≥ 4 /- 15 multiplying by a negative number reverses the sign.

Three times the sum of a number and 7 is equivalent to 57.
Answers
Answer:
3(x+7)=57
Step-by-step explanation:
3 is being multiplied by "the sum of a number(or x) and 7". So, we write it as 3(x+7). That is equal to 57, so that makes the expression 3(x+7)=57.
-hope it helps
Equivalent expressions are expressions that have the same values.
The expression is [tex]3(x + 7) = 57[/tex] and the number is 12
Represent the number with x.
So, the sum of a number (x) and 7 would be represented as: x + 7
Three times the sum would be represented as: 3(x + 7)
This expression is equivalent to 57.
So, we have:
[tex]3(x + 7) = 57[/tex]
Divide both sides of the equation by 57
[tex]x + 7 = 19[/tex]
Subtract 7 from both sides of the equation
[tex]x + 7 - 7 = 19 - 7[/tex]
[tex]x = 12[/tex]
Hence, the number is 12
