Solve for c in a+b+c=180

Answers

Answer:

c = -a - b + 180

Step-by-step explanation:

Isolate the c. Note the equal sign, what you do to one side, you do to the other. Subtract a and b from both sides

a (-a) + b (-b) + c = 180 (-a) (-b)

c = 180 - a - b

c = -a - b + 180 is your answer

79% of 67 miles is what?

Answers

79% of 67 miles is approximately 52.93 miles as per the concept of percentage.

To find 79% of 67 miles, we can use the concept of percentage as a fraction of a whole.

When we say "79% of 67 miles," we are asking for 79% of the total distance of 67 miles.

To calculate this, we convert the percentage to a decimal by dividing it by 100: 79% = 79/100 = 0.79.

Now, to find 79% of 67 miles, we multiply the decimal (0.79) by the total distance (67 miles):

0.79 x 67 miles = 52.93 miles

Therefore, 79% of 67 miles is approximately 52.93 miles.

In conclusion, when we talk about a percentage of a quantity, it represents a proportion of the total. In this case, 79% of 67 miles means 79% of the total distance of 67 miles, which is calculated by converting the percentage to a decimal and then multiplying it by the total distance. The result is approximately 52.93 miles.
