Hi! For this problem, you must replace the letter “X” with the number 2. Your equation will then be (2*1)- (2-1)+ (2*0). This will then simplify to: 2 - 1 + 0. Therefore, your final answer will be:
1
1. 4b - 2 : the product of 4 and a number (b) decreased by 2
2. the sum of 15 and 4 times a number......15 + 4x
3. 8 fewer boys then girls...how many boys.......b = g - 8
4. It will be less then 1 because of the negative exponent....a negative exponent will mean the number is less then 1...I dont really know how else to explain it.
5. Doug is twice Anna's age...doug is 34 years old
I dont know the 5 step plan...but I am putting what I do know
d = doug's age
a = anna's age
d = 2a
d = 34
34 = 2a
34/2 = a
17 = a....so anna is 17
check..
d = 2a
d = 2(17)
d = 34 (correct)
Answer:
The radius is 4.5, while the area is equaled to 63.585
Step-by-step explanation:
Formula of circumference: radius times 2 times pie (3.14)
Formula of Area of Circle: radius squared times pie (3.14)
Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.
Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.

Answer:
Mean
Step-by-step explanation:
Since 360 is such a greater amount of time than the previous ones, it will greatly affect the mean.
