5g + 3(-7 + 5g) = 1 - g
5g - 21 + 15g = 1 - g
20g - 21 = 1 - g
20g + g = 1 + 21
21g = 22
g = 22/21 <===
Answer:
1. 0.875 2. 0.666… 3. 2.25 4. 0.8333…
Step-by-step explanation:
The easiest way to convert a fraction to a decimal is to divide the numerator (the top of the fraction) by the denominator (the bottom of the fraction) by using a calculator. The resulting answer will be the value of the fraction expressed as a decimal number. Hope you get it! :)
I found an image that has a similar problem.
The squares were in a diamond form. There were six squares. To get the length of the path, I have to solve for the diagonal of the square.
To solve for the diagonal of the square, I have to multiply the length one side by the square root of 2.
diagonal of one square = 15 in * √2 = 21.21 in
21.21 in * 6 squares = 127.28 inches
The length of the path is 127 inches.
