Answer:
-72
Step-by-step explanation:
There are multiple ways to do this.
The easiest is to just continuously subtract 7 from 65 the numbers of times needed.
But most math teachers will have you use the equation ar^n-1 where a= the first term (65), r=ratio (-7), and n=the term you need (second, fifth, and ninth).
So to solve you just plug your values in as so
AR^n-1
(65)(-7)^2-1(65)(-7)^5-1
(65)(-7)^9-1
Refer to the diagram shown below.
FH = FG + GH, therefore
(5x + 9) + (9x - 5) = 102
5x + 9 + 9x - 5 = 102
14x + 4 = 102
Subtract 4 from each side.
14x = 98
Divide each side by 14.
x = 7
FG = 5x + 9 = 5*7 + 9 = 35 + 9 = 44
HG = 9x - 5 = 9*7 - 5 = 63 - 5 = 58
Answers:
Part A) x = 7
Part B) FG = 44
Part C) HG = 58
1 ton= 2,000 pounds
16 tons= 32,000 pounds
3 pounds = 3 pounds
32,000 pounds+ 3 Pounds =
32,003 pounds
