To solve the equation w = 9x + 5y for y, subtract 9x from both sides to get w - 9x = 5y. Then, divide every term by 5 to obtain y = (w - 9x) / 5
Explanation:To solve the equation w = 9x + 5y for y, you should first isolate y on one side of the equation. This involves a series of steps.
Start by subtracting 9x from both sides of the equation. This will give you w - 9x = 5y.Next, divide every term in the equation by 5 to solve for y. This would give you (w - 9x) / 5 = y or y = (w - 9x) / 5.Now, the equation has been solved for y, meaning you can now substitute any values for w and x into this equation to find the corresponding value for y.

A machine laying underground cable can place 125 meters of cable in 5 minutes
The machine lays cable at a rate of 25 meters per minute. This is calculated by dividing 125 meters by 5 minutes.
To determine how quickly the machine can lay underground cable, we need to calculate the rate of cable it places per minute. We start by noting that the machine can lay 125 meters of cable in 5 minutes.
We calculate the rate as follows:
Divide the total length of cable by the total time: 125 meters / 5 minutes = 25 meters per minute.This means the machine lays cable at a rate of 25 meters per minute.
Complete Question: A machine laying underground cable can place 125 meters of cable in 5 minutes. What is the rate per minute?

determine whether each equation is a linear equation. write yes or no. if yes, write the equation in standard form. if the answer is no, circle the part that makes it no
1. y = 4 - 2x
The given equation y = 4 - 2x is a linear equation, however, it is not in standard form. The standard form is 2x + y = 4.
Explanation:The equation y = 4 - 2x is indeed a linear equation. A linear equation is an equation that represents a straight line when graphed. It generally has the form 'y = mx + b' where 'm' represents the slope of the line, and 'b' represents the y-intercept. Here, 'm' is -2 and 'b' is 4.
However, it is not currently in standard form. The standard form of a linear equation is 'Ax + By = C', where A, B, and C are integers, and A and B are not both zero. To write the equation in standard form, we can re-arrange it as 2x + y = 4.

Which product represents the fraction of the circle that is shaded?
A. 3/4 x 1/2
B. 2/3 x 3/4
C. 1/4 x 3/4
D 3/4 x 3/4
Answer:
D 3/4 × 3/4
Step-by-step explanation:
The part of the circle that is black is 1/4 of the circle. The remaining 3/4 is divided by the dashed lines into 4 equal parts, so each of those parts is 1/4 of 3/4 of the circle. 3 of the parts are shaded blue, so those represent ...
... 3/4 × 3/4 . . . of the circle
The correct product that represents the fraction of the shaded circle is D. 3/4 x 3/4.
Explanation:The correct answer is D. 3/4 x 3/4.
The fraction represents the shaded part of the circle. We can determine the shaded area of the circle by multiplying the fraction of the radius by the fraction of the circumference that is shaded. In this case, 3/4 x 3/4 would yield a product that represents the fraction of the circle that is shaded.

x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees

A pizza parlor has 8 different toppings and 3 different cheeses to choose from on the menu. How many pizza combinations are possible if each pizza has 1 topping and 1 cheese
Final answer:
To find the number of pizza combinations available using 1 topping and 1 cheese from 8 different toppings and 3 different cheeses, one multiplies the number of topping choices by the number of cheese choices, giving 8 x 3 = 24 possible combinations.
Explanation:
Calculating Pizza Combinations
When calculating the number of possible pizza combinations with 1 topping and 1 cheese from 8 different toppings and 3 different cheeses, we use basic counting principles. Each pizza can be thought of as a combination of one topping and one cheese. Since these choices are independent, we multiply the number of options for toppings by the number of options for cheeses to find the total combination possibilities. This results in 8 toppings multiplied by 3 cheeses, giving 24 possible combinations.
The formula used is straightforward: Number of combinations = Number of toppings × Number of cheeses.
Pizza Combination Calculation Example
For instance, if you were at a pizza parlor where you could choose from pepperoni, mushrooms, onions, and 5 other toppings, along with mozzarella, cheddar, and one other cheese, you could create 24 unique pizzas. Just pick one topping and one cheese, and that's your combination.
What is another way to write 46
Final answer:
The number 46 can be written as 'forty-six', 'XLVI' in Roman numerals, '101110' in binary, '56' in octal, '2E' in hexadecimal, a sum or product of other numbers, or in scientific notation as 4.6 x 10ⁱ.
Explanation:
There are several ways to write the number 46 in mathematics. One alternative way to express the number is by using words, such as 'forty-six'. Another method is to use Roman numerals, which would be 'XLVI'. Additionally, 46 can be represented in other numerical bases; for example, in binary, it is '101110', in octal, it is '56', and in hexadecimal, it is '2E'. If we dive into mathematics, 46 can also be written as a sum of other numbers, such as 23 + 23, or a product of primes, which for 46 is 2 x 23. Lastly, 46 can be expressed in scientific notation as 4.6 x 10±, though this form is more commonly used for very large or very small numbers.

Final answer:
To find the remainder of the polynomial division of x^7 + x^5 + 1 by x^3 + 1, one would perform polynomial long division or synthetic division, continuing until the degree of the remainder is less than the divisor.
Explanation:
The student is asking how to find the remainder of a polynomial division. Specifically, they want to know the remainder when dividing x^7 + x^5 + 1 by the polynomial x^3 + 1. To solve this, one would typically use long division of polynomials or synthetic division. The process is similar to long division with numbers. We would start by looking at the highest degree terms of both polynomials and divide them, then multiply the divisor by the result and subtract from the dividend. Repeat this process until the degree of the remainder is less than the degree of the divisor. Since finding the remainder requires us to consider terms up to x^2, we are essentially looking for the result of division that does not perfectly divide, similar to how 7 divided by 3 leaves a remainder.
