Answer:
18.8 billion dollars
Step-by-step explanation:
S - 1.7x = 5.2
x = 2006 - 1998 = 8
S - 1.7(8) = 5.2
S - 13.6 = 5.2
S = 5.2 + 13.6
S = 18.8
Answer:
the last one on the bottom
Step-by-step explanation:
Answer:
Step-by-step explanation:
The problem statement defines the variables and gives the relations ...
2b + f = 8 . . . . total cost on Monday
3b + f = 11 . . . . total cost on Tuesday
__
Subtracting the first equation from the second, we get ...
(3b +f) -(2b +f) = 11 -8
b = 3 . . . . . simplify
Substituting this into the first equation, we can solve for f
2·3 +f = 8
f = 2 . . . . . . . subtract 6
Bagels cost $3 per dozen; the delivery fee is $2.
2x + (y + x) = 180 [Supplementary angles]
2x + y + x = 180
3x + y = 180 ---------- (1)
(y + x) + (y - x) = 180 [Supplementary angles]
y + x + y - x = 180
2y = 180
y = 90 --------------- sub into (1)
3x + 90 = 180
3x = 90
x = 30
Ans: x = 30, y = 90
