Answer:

5

Step-by-step explanation:

-8x + 25 = -15

                 -25 = -40  then

-40 divide -8 to get 5

Answer: x = 5

The first step of the inverse operation is to subtract 25 on both sides of the equation to cancel out the 25 from the left side:

-8x+25 (-25) = -15 (-25)

-8x = -40

Next, you need to divide -8 on both sides to isolate the variable, which would give you the answer to x. The negatives would cancel out, leaving you with: x = 5

hope that helps :)

Step-by-step explanation:

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Answer:

Step-by-step explanation:

Let be cost price =Rs.100

Then mark price =Rs.120

∴ Selling price =90% of 120

120×90

​

=Rs.108

Profit = Selling price− Cost price

=Rs.(108−100)=Rs.8

Profit % =

Answer: He bought 46.875 pounds of rice for the week.

Step-by-step explanation:

Total rice he bought = (Number of dishes made in a week) x (portion of rice in each dish)

GIven: Each portion has 5 ounces of rice.

i.e. each portion has [tex]\dfrac{5}{16}[/tex] pounds of rice.    [ 1 pound = 16 ounces]

Total rice he bought ( in pounds)=[tex]150\times\dfrac{5}{16}[/tex]

[tex]=46.875\text{ pounds}[/tex]

Hence, he bought 46.875 pounds of rice for the week.

y=4,000x+50,000

Step-by-step explanation:

Where y = total salary

x = number of years worked

The relationship between salary and the number of years working at the company is 50000 + 4000x

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Gabriella was offered a job after college earning a salary of $50,000.

She will get a raise of $4,000 after each year working for the company.

let the number of years worked be x.

Then, relationship between salary and the number of years working at the company is 50000 + 4000x
