Answer:

x = 12

Step-by-step explanation:

By the alternite intereor angle therom, the two expresions equel each other

8x - 15 = 3x + 45

8x -3x - 15 = 3x - 3x + 45

5x - 15 = 45

5x - 15 + 15 = 45 + 15

5x = 60

5x/5 = 60/5

x = 12

Write a division problem that has a two digit quotient that is greater than 40 but less than 50.
trasher [3.6K]

Let

x--------> Dividend

y-------> Divisor

Q-------> Quotient

we know that

\frac{x}{y} = Q

solve for x

x=Q*y

40 < Q < 50

Examples

example 1

Q=45\\ y=4

Find the value of x

x=45*4\\ x=180

A division problem is equal to

\frac{x}{y} =\frac{180}{4} \\\\ = 45

example 2

Q=42\\ y=10

Find the value of x

x=42*10\\ x=420

A division problem is equal to

\frac{x}{y} =\frac{420}{10} \\\\ = 42

Solving Square Roots Worksheet (x - k)^2 : Part 1
iVinArrow [24]

Answer:

1. x = +/- 2\sqrt{2} - 7

2. x = 3 +/- 2i\sqrt{3}

3. n = 2 +/- i\sqrt{2}

Step-by-step explanation:

1. Divide both sides by 2: (x + 7)^2 = 8

Square root both sides: x + 7 = +/- 2\sqrt{2}

Subtract 7 from both sides: x = +/- 2\sqrt{2} - 7

2. Square root both sides: x - 3 = \sqrt{-12}

Since there is a negative inside the radical, we need to have an imaginary number: i=\sqrt{-1} . So, \sqrt{-12} =i\sqrt{12} =2i\sqrt{3}

Add 3 to both sides: x = 3 +/- 2i\sqrt{3}

3. Divide by -5 from both sides: (n - 2)^2 = -2

Square root both sides: n - 2 = \sqrt{-2}

Again, we have to use i: n-2=\sqrt{-2} =i\sqrt{2}

Add 2 to both sides: n = 2 +/- i\sqrt{2}

Hope this helps!
