Answer:
Required equation is 42 = 5 + 3.70d
Step-by-step explanation:
Emma took a taxi from the airport to her house. She paid a flat fee of $5 plus $3.70 per mile.
The fare came to $42
Flat fee = $5
Variable fee = $3.70 per miles
Total fare = $42
Let Emma traveled d miles
Total fare = Flat fee + variable fee of d miles
According to given info.
42 = 5 + 3.70d
Now we solve for d,
Therefore, d=10 miles
Thus, Required equation is 42 = 5 + 3.70d , d=10 miles

Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176

40 pages = 80 minutes
210 pages = ? minutes
Well, take the first fact; 40 pages in 80 minutes and use it to find how many pages per minute.
40/80=1/2
1/2 pages = 1 minute
1 page = 2 minutes
210 pages = ? minutes
210*2=420
420 minutes = 7 hours
210 pages = 7 hours
Hope this helped :)
