Answer:
The unknown information is how many months she will use her phone, and how many GB she will download. We can represent these with literally any non-number symbol, letters, greek letters (if ur cool), but to simplify it we can represent the number of months with 'm' and the number gigabytes with 'g'
21m + 3g ≤ 30
Step-by-step explanation:
Assuming that you want to add or subtract them and want the bottom number the same,
1/4 and 2/3
least common multiple of 4 and 3
4=2 times 2
3=3 times 1
so the leas common mulltiple will include all of them
the number is 2 times 2 times 3 or 12
lcm=12
1/4 times 3/3=3/12
2/3 times 4/4=8/12
add or subtract 3 and 8
LCM=12
Answer:
-70 is the correct answer
Assuming they start saving at 0 dollars
45=total=duanesavings+micksavings
duanesavings=confusing, I will explain
mick savings =amount saves per week times number of weeks
duane saves 5 dollars every other week, aka 2.5 dollars per 1 week
DS=2.5w
MS=2w
since they save at same time and at that week, when the weeks are equal (w=w), 45 it total
DS+MS=45
2.5w+2w=45
4.5w=45
divide by 4.5 both sides
w=10
10 weeks
