Answer:

x=6

Step-by-step explanation:

x is a variable, meaning it represents an unknown value.

To solve equations, you need to solve for x.

The first step is isolating x.

To isolate x, get it alone.

Start by subtracting 2 from <u>both</u> sides.

x = 6

There is your answer.

Answer:

Subtract two from 8, the remainder is x. In this case, it is 6.

For future questions, try to think of x as a mystery number rather than a letter. You got this. :)

The system of equations shown is solved using the linear combination method
andriy [413]

Answer: When a system of two linear equations gives an answer of 0=0, there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.

Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:

1. When you get an exact value & number for x and y, the system has <u>one solution</u> and is consistent/independent.

2. When you get 0=0 like in this case, the system has <u>infinitely many solutions</u> and is consistent/dependent.

3. When you get numbers that are not equal, for example, 3\neq 5, you have <u>many solutions</u> and the system is inconsistent/independent.

Multiply both sides of the original equation by x, and find the solution set of the new equation.
prisoha [69]

Answer: (0, 1) Usually, we put the solutions in parenthesis.

Step-by-step explanation: x(x+1) = x(2) which = x²+ x = 2x = x² + x - 2x = 0

x² - x = 0. Now we divide by x which = x(x - 1) = 0 and the new solution set is x = 0 and x -1 = 0 which equals x = 1

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?
joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many  beads are purple, multiply the total beads by the fraction of the beads that are purple

so

18(\frac{3}{6})=9\ beads

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

\frac{3}{6}=\frac{1}{2}=0.50*100=50\%

so

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
