An angle measures 42° less than the measure of a complementary angle. What is the measure of each angle?

Answers

Answer 1

Answer: Complimentary angles add to 90 degrees. So if you have an angle, x, and another angle, x - 42, they should add together to equal 90...

x + x-42 = 90
2x - 42 = 90
2x = 132
x = 66 degrees (1st angle)

66 - 42 = 24 degrees (2nd angle)

*Check 66 + 24 = 90 :)

Answer 2

Answer: Complementary angles will add up to 90 degrees.
Let X = one of the angles
Let X - 42 = the other angle
X + X - 42 = 90
2X - 42 = 90
2X = 132
X = 66
X - 42 = 24
Check 66 + 24 = 90

A quarter is what fraction of a dollar

Answers

A quarter is equal to 25 cents.

We have,

To determine the fraction that represents a quarter of a dollar, we need to compare the value of a quarter to the value of a dollar.

Since there are 100 cents in a dollar, a quarter is equal to 25/100 of a dollar.

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 25. Dividing 25 and 100 by 25 gives us:

25/25 = 1

100/25 = 4

Therefore,

A quarter is equal to 1/4 of a dollar.

10x=120 what is x i know this but i will give you guys a chance

Answers

first simplify 10x = 120 then solve 10x = 120 to solving for variable 'x' move all terms containing x to the left, all other terms to the right. then divide each side by '10'. x = 12 is ur answer ^-^ hope this helps

Solutions

10x=120

1) Divide both sides by 10 to isolate variable x

x = 120 ÷ 10

2) Simplify 120 ÷ 10 to 12

x = 12

A train has an average speed of 18 miles per hour. How long will it take to travel 270 miles?

Answers

It will take 15 hours. Because the train has a speed of 18 mph, you just have to divide 270 by 18 which makes 15. The train goes 18 mph, so it is 15 hours.

Step-by-step explanation:

1.) First, you need to find how many miles per hour (18), and how many miles (270)

2.) Next, you will need to divide 270 by 18, or 270/18.

3.) This will show you how many 18's you can get out of 270, or how many hours it will take to go 270 miles.

4.) After dividing, you will get 15.

Therefore, it will take you 15 hours to get from point A to point B.
