Answer:
a)Yes, π = 2 is a solution.
Step-by-step explanation:
a) 4π - 3 = -2π + 9
π = 2, so put this value on above equation.
4×2 - 3 = -2×2 + 9
8 - 3 = -4 + 9
5 = 5
So, π = 2 is a solution
Answer:

Step-by-step explanation:
first calculate expense for each week;
25+30+40= 95
expense after saving
25-7= 18
30-7=23
40-7=33
18+23+33= 74
total saving for each week= 95-74=21
(you can also just do 7*3=21 to know total saving each week)
weeks in a year=
365 days/7= 52.14 = 52 weeks
total savings for the year= 52*21=$1092
You can write 57,467/1,000
A number decreased by seven
