To solve the equation y = 4x + 8x for x, isolate x by combining like terms on the right side and dividing both sides by 12. The solution is x = y/12.
Explanation:To solve the equation y = 4x + 8x for x, we need to isolate x on one side of the equation.
We can start by combining the like terms on the right side:
12x = y
To find the value of x, divide both sides of the equation by 12:
x = y/12
So the solution to the equation is x = y/12.
To solve the equation y = 4x + 8x for x, combine like terms to get y = 12x and then divide both sides by 12 to find x = y/12.
Explanation:The student's question requires us to solve the given equation for x. The original equation provided is y = 4x + 8x. To solve for x, we first combine like terms on the right side of the equation.
Combine like terms: y = 4x + 8x becomes y = 12x.Divide both sides of the equation by 12 to isolate x: x = y/12.The solution for x is x = y/12. This is a straightforward algebraic manipulation that involves combining like terms and using division to solve for the unknown variable.

Max recorded the math scores of five of his classmates in the table. What is the range of their test scores? 16 24 88 89
Math Scores98761008882
Answer:
B. 24
Step-by-step explanation:
We have been given a data set that represents the math scores of five of Max's classmates. We are asked to find the range of the given data set.
Math score: 98, 76, 100, 88, 82.
Since we know range is the difference between the largest and smallest values of the data set.
[tex]\text{Range}=\text{The largest value of data set - The smallest value of data set}[/tex]
We can see that largest score is 100 and smallest score is 76.
[tex]\text{Range}=100-76[/tex]
[tex]\text{Range}=24[/tex]
Therefore, the range of the given test scores is 24 and option B is the correct choice.

Find the number of sides when:
a. The measure of each interior angle of a regular polygon is 156 degrees.
b. The measure of each exterior angle of a polygon is 36 degrees.
Final answer:
To find the number of sides of a polygon, one can use the relations between interior or exterior angles and the number of sides. For an interior angle of 156 degrees, the polygon has 15 sides. For an exterior angle of 36 degrees, the polygon has 10 sides.
Explanation:
The question is about finding the number of sides of a polygon based on the interior and exterior angles. For part (a), where the measure of each interior angle of a regular polygon is 156 degrees, and for part (b), where the measure of each exterior angle is 36 degrees, we can use specific formulas to find the number of sides.
Part A: Interior Angle 156 Degrees
For a regular polygon, the formula connecting the number of sides (n) to an interior angle (A) is A = [(n-2) * 180] / n. Solving for n when A = 156 degrees gives us:
156 = [(n-2) * 180] / n
Solving this equation yields n = 15, meaning the polygon has 15 sides.
Part B: Exterior Angle 36 Degrees
The measure of each exterior angle of a polygon (E) is related to the number of sides (n) by the formula E = 360 / n. When E = 36 degrees:
36 = 360 / n
Solving for n gives us n = 10. Therefore, the polygon has 10 sides.

Step-by-step explanation:
A and B have coordinates –2 and 10 on a number line. If it is marked off into 10 congruent segments, which one of the following coordinates is NOT one of the marked points? a. –0.8 c. 1.6 b. –0.6 d. 2.8
Answer:
b. - 0.6
Step-by-step explanation:
Since, the total coordinates from -2 to 10 = 10 - (-2) = 10 + 2 = 12,
Also, if it is divided into 10 congruent segments,
Then, the length of each segment = [tex]\frac{12}{10}[/tex] = 1.2,
That is, the difference between the marked point is 1.2,
So, the marked points from -2 to 10 are,
-2, -0.8, 0.4, 1.6, 2.8, 4.0, 5.2, 6.4, 7.6, 8.8, 10,
Hence, except -0.6 all points are the marked points,

As per the statement:
Labelled the diagram:
then;
PA = 14 units , AB = 20 units, PC = 16 units and CD = d units
Find PB and PD:
PB = 14+20 = 34 units
PD = 16+d units
then by above definition we have;
[tex]PA \cdot PB = PC \cdot PD[/tex]
⇒[tex]14 \cdot 34 = 16 \cdot (16+d)[/tex]
⇒[tex]476=16 \cdot (16+d)[/tex]
Divide both sides by 16 we have;
[tex]29.75 = 16+d[/tex]
Subtract 16 from both sides we have;
13.75 = d
or
d = 13.75 units
Therefore, the value of d to the nearest tenth is, 13.8

What is the sum of this geometric series?5 + 25 + 125 + 625 + 3,125 + 15,625?
The sum of the given geometric series (5 + 25 + 125 + 625 + 3,125 + 15,625) is -78120.
Explanation:The question is asking for the sum of a geometric series. In a geometric series, each term is multiplied by a common ratio to get the next term. In this case, the first term (a) is 5 and the common ratio (r) is 5 (since we get each term by multiplying the previous one by 5).
The sum (S) of the first n terms of a geometric series can be calculated using the formula S = a * (1 - r^n) / (1 - r). In this case, there are n=6 terms in the series, so we will plug these values into the formula.
Therefore, S = 5 * (1 - 5^6) / (1 - 5). So, the sum of this geometric series is -78120.

Find the arc length of a central angle of 7pi/3 in a circle whose radius is 3 inches
To calculate the arc length, multiply the angle in radians (7pi/3) by the radius (3 inches). After simplifying, the arc length for this circle is 21 inches.
To find the arc length for a central angle of 7pi/3 radians in a circle with a radius of 3 inches, we use the formula for arc length, which is the product of the central angle in radians and the radius of the circle.
The formula for the arc length (As) is given by:
As = r times theta
Where:
r is the radius of the circle.
theta is the central angle in radians.
Substituting the given values, we get:
As = 3 inches times 7pi/3 radians
The 7pi/3 terms cancel out the pi/3 from the angle and /3 from the radius, giving us:
As = 3 times 7 inches
The arc length is therefore 21 inches.
