Answers

Answer 1
Answer:

Answer:

200.43 yds

Step-by-step explanation:

84 x 84 = 7,056

70 x 70 = 4,900

7,056 - 4,900 = 2,156

√(2156) = 46.43

84 + 70 + 46.43 = 200.43 yds

What is the first step in solving 3x+4=20

Answers

Answer:

Subtract four on both sides.

Step-by-step explanation:

When we solve for x, we do the reverse of PEMDAS. The last letter is S, so we subtract. There is no subtraction, so we move to A for addition. There is addition, the plus 4, so to get rid of it, we subtract 4 on each side.

Answer: Subtract 4 from both sides of the equation.

Step-by-step explanation: In algebra, the equal sign separates and equation. 20 is a separate part. You would take the +4 and subtract it from itself and then also subtract 4 from the 20 which would give you 3x=16

What is 65% written as a fraction in simpliest form.

Answers

Any number expressed as a percentage may be written as: number / 100. In this case, this becomes 65/100. In order to simplify this fraction, we take the highest common factor of the numerator and denominator, which works out to be 5. The fraction then becomes 13/20
I hope that my answer is helpful! Let me know if you need something more :)

65% written as a fraction in simplest form is 13/20.

To express 65% as a fraction in its simplest form, you need to convert the percentage to a fraction with a denominator of 100 (since percentage means "per 100").

Divide the percentage value by 100:

65% = 65/100

Now, to simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator and then divide both by the GCD to get the simplest form:

The greatest common divisor of 65 and 100 is 5.

Divide both the numerator and denominator by 5:

(65 ÷ 5) / (100 ÷ 5)

= 13/20

So, 65% written as a fraction in simplestform is 13/20.
