The angles are vertical angles. Vertical angles measure the same. That means:

2 + 3x = 62

Switch it around and it becomes:

62 - 2 = 3x

The sign changes. At first you were adding, and now you're subtracting. Subtract:

62 - 2 = 60 \\ 3x = 60

Divide both sides by 3 to leave the variable alone:

60 \div 3 = 20 \\ 3x \div 3 = x

That means x = 20°

The two angles are vertical angles so that means they must be equal to each other. Make them equal to each other in an equation.

(2 + 3x) = 62

Subtract 2 from both sides.

3x = 60

Divide both sides by 3.

x = 20

Answer:

<h3>(-4, 1)</h3>

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4

-5y = 4-9

-5y = -5

<h3>y = 1</h3>

_______________

Find the value of x

x = -y-3

x = -1-3

<h3>x = -4</h3>

_______________

Answer (x, y) =

<h3>(-4, 1)</h3>

I need help with this ASAP!!!!
Yanka [14]

Answer:

20

Step-by-step explanation:

The distance between two points is found by

d = sqrt( ( x2-x1)^2+(y2-y1)^2

  = sqrt( ( 10- -6)^2 + (-4 -8)^2 )

  = sqrt( (16^2 + (-12 )^2)

  = sqrt(256+144)

  = sqrt(400)

   = 20

Which expression is equivalent
VLD [36.1K]

Answer:

B)

Step-by-step explanation:

You must divide these fractions with square roots:

18x^{2}\sqrt{14x^8} / 6\sqrt{7x^4} = 3x^{2} \sqrt{2x^4} = 3x^{2}\sqrt{2}x^{2} = 3x^4\sqrt{2}

logan recieved a raise of $5 per hour. He made $12 per hour before the raise. By what percent did his salary increase? Round to
Nikitich [7]

This is pretty basic, but you need to convert the percentage into a real number that you can use to multiply by the employee’s current pay rate. To do this, simply move the decimal two places to the left. For a 3% increase, you will use .03.

Step 2: Multiply the employee’s current pay rate by that decimal

If your employee makes $15/hour, then you have: 15x.03=.45. So your employee’s increase is 45 cents per hour. For an employee who makes a salary of $45,000/year, then you have: 45,000x.03=1,350. So your salaried employee’s pay increase is $1,350 per year.

Why You Have to Convert the Percent

This is just a little theory and not needed to do the problem.

The percent symbol is used to tell you something about the number it sits beside. Percent means ‘parts per hundred’. So if a % sign sits beside a 3, it really means 3 parts per 100. You don’t need to know this to calculate a pay increase but it might help you to understand why you need to convert the percent into decimal form to begin with. 3% tells us we need to multiply our pay rate by 3 pieces of a hundred.

Do you remember what the decimal places mean? The first decimal place is the tenths place and the second is the hundredths place. This is why when we convert our percent we have to move two places – we have to open up the hundredths place.

Automatic Pay Raise Calculations

The Human Resources Documents within the Timesheets.com time tracking service calculates pay raise percentage as well as keeps record of changes. Record keeping is required by the
