Step-by-step explanation:
3c + 3s = 12.50
4c + 2s = 10.00
3S = 12.50-3c
s = 4.17 - c
4c + 2 (4.17-c) = 10.00
2c + 8.34 = 10.00
2c = 1.66
chips = 0.83
soda = 3.34
10^9 (Ten to the power of nine)
Answer:
11,18,25
Step-by-step explanation:
add 7
The area of a circle in terms of the circle's radius
is
Differentiating both sides with respect to
, you get
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
