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)
