Answer:
0.75
Step-by-step explanation:
increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.
when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.

Circumference of a circle is found with the equation
C = 2 × pi × r
where r is the radius. So for your problem...
C = 2 × 3.14 × 4
C = 25.12 meters
7x +33 < 26 isolate the term with a variable by subtracting 33
7x < -7 divide by 7
x < -1
Equation is 25x + 100 is greater than or equal to 700. First subtract 100 from 700. Then divide 600 by 25 = 24. Sharon must Sell greater than or equal to 24 items
