Answer:30x=840 30 represents the number of days and x represents miles per day
b)yes because 30 (28)= 840 miles
c)yes because 30(40)= 1200 miles and the question said at least 840 so it can be more
d)30(11)=330
e) 10,800- 4,015 miles =6785 miles will be saved

We know that one yard is equivalent to 0.9144 meters.
We are given the number of yards = 5 (1/4) yards. To know the equivalent number of meters, all we have to do is cross multiplication as follows:
number of meters = (5 1/4 * 0.9144) / 1 = 4.8006 meters
Rounding the answer to the nearest tenth, we would get 4.8 meters
Answer:
"Dominic lived in Spain for 13 months and Columbia for 7 months."
Step-by-step explanation:
let months stayed in spain be "s" and months stayed in columbia be "c"
We can write 2 equations.
Since, lived in Spain and Columbia for a total of 20 months, we can write:
s + c = 20
Also, since 120 words per month in Spain and 150 words per month in Columbia for a total of 2610 new words, we can write:
120s + 150c=2610
Solving first for s:
s = 20 - c
Putting in 2nd and solving:
120(20 - c) + 150c = 2610
2400 - 120c + 150c = 2610
30c = 210
c = 7
Now,
s = 20 - c = 20 - 7 = 13
So
"Dominic lived in Spain for 13 months and Columbia for 7 months."
