Answer:
assuming that kyle crawled at the same pace for six minute then it would be 8.3 feet each minute
Step-by-step explanation:
Do this.
38 divided by two
then use the equation
38=5+2x
If it is 50 pages in an hour, half an hour would be 25 pages, and if it is 40 pages in an hour it would be 20 pages in half an hour, the answer is 5 pages more in half hour
2x+y=25
3x-y=20
solve by adding these two equations together
2x+3x=5x
y-y=0
25+20=45
you get left with
5x=45
divide both sides by 5
x=9
then plug x=9 into one of the 1st equations to solve for y
2(9)+y=25
18+y=25
subtract
y=7
so your numbers are 9 and 7
