5.7 + 6.2 = 11.9 You can round it, but you don't need to. Really. Round it becomes 12. Then its more clear. But if you don't round, it is more exact.
Two negatives equals a positive:
Add the numerators and keep the denominator:
Answer:
c 12.6 inches
Step-by-step explanation:
radius = diameter/2 =4/2 =2 inches
circumference = 2πr
= 2× 22/7 × 2 = 12.6 inches
The first bullet is the answer
Answer:
Three ways to find the slope of a line: You may have two points #(x_1,y_1)# and #(x_2,y_2)# (often one or both of these points may be intercepts of the #x# and/or #y# axes). The slope is given by the equation. #m=(y_2-y_1)/(x_2-x_1)#. You may have a linear equation that is either in the form or can be manipulated into the form. #y = mx + b#.
