Answer:
A. 3.6×10^5 grams
Step-by-step explanation:
Multiply the number of people by the amount per person:
(1.8×10^3)(2×10^2 g) = 3.6×10^5 g
__
The applicable rule of exponents is ...
(10^a)(10^b) = 10^(a+b).
In a coincidental system both equations are the same. I try to transform one equation into the other:
2 x + 3 y = -17 /*6
12 x + 18 y = -102
18 y = -12 x - 102
First we need to know how many miles per hour they drove the first time. This would be found by division. 168/3.5=48
Then we need to add 5 miles per hour for the average.48+5= 53
Next we need to multiply 2 1/4 by the new miles per hour 53*2.25=119.25
After that we need to know how many miles they drove 119.25+168=287.25 miles.
Finally to get an improper fraction we need to change 287.25 miles to it.
We already have 1/4 for .25 so we multiply 287 by 4 and add it to the 1/4 we already have and it makes it out to be 1149/4
Hope this helps!
