Step-by-step explanation:
5-4b ; b=-3
- substitute b= -3 into the expression
5-4×(-3)
- multiply the numbers

Step-by-step explanation:
<span> the total distance around the pie is the circumference of the pie, assuming that the pie is a perfect circle then the formula for the circumference of a circle is:
c = piD
where pi is equal to 3.1416
D is the diameter of pie or circle
substitute the given values
C = (3.1416) ( 20 ft
c = 62.832 ft

Answer:
6 : 11
Step-by-step explanation:
the ratio 6 : 11 applies to all linear measure in the similar polygons
Both side lengths and perimeter are linear, hence
ratio of both is 6 : 11
M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)
M=103
So martha has 103 coins!
