Step-by-step explanation:

Sum of opposite angles are supplementary,

x + 60 + 3x = 180

4x + 60 = 180

4x = 180 - 60

4x = 120

x = 120 / 4

x = 30

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.

A circular hedge surrounds a sculpture on a square base. The radius of the hedge is 6x. The side length of the square sculpture
andrey2020 [161]
Hi, thank you for posting your question here at Brainly.

Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.

A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)

I hope I was able to answer your question. Have a good day.

5-2(4a+1)+3a=13 <br><br> A= 2/3<br> A= -2<br> A= -6/5<br> A=2
VMariaS [17]

Answer:

                   a = -2

Simplifying 5 + -2(4a + 1) + 3a = 13 Reorder the terms: 5 + -2(1 + 4a) + 3a = 13 5 + (1 * -2 + 4a * -2) + 3a = 13 5 + (-2 + -8a) + 3a = 13 Combine like terms: 5 + -2 = 3 3 + -8a + 3a = 13 Combine like terms: -8a + 3a = -5a 3 + -5a = 13 Solving 3 + -5a = 13 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5a = 13 + -3 Combine like terms: 3 + -3 = 0 0 + -5a = 13 + -3 -5a = 13 + -3 Combine like terms: 13 + -3 = 10 -5a = 10 Divide each side by '-5'. a = -2
