Answer:
y = 2x
Step-by-step explanation:
Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:
1 present wrapped -> 2 centimeters of tape
x presents wrapped -> y centimeters of tape
1/x = 2/y
x = y/2 -> y = 2x
From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
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!
