Answer:
It would take him approximately 16.62 minutes to reach the bookstore
Step-by-step explanation:
Total steps to the bookstore=Number of steps per minute×number of minutes
where;
Total steps to the bookstore=864 steps
Number of steps per minute=52
Number of minutes=t
Replacing;
864=52×t
t=864/52
t=16.62 minutes
It would take him approximately 16.62 minutes to reach the bookstore
Answer:x=3 y=1/2
Step-by-step explanation:
x+2y=4
2x-2y=5
Add both equations together
x+2x+2y-2y=4+5
3x+0=9
3x=9
Divide both sides by 3
3x/3=9/3
x=3
Substitute x=3 in x+2y=4
x+2y=4
3+2y=4
Collect like terms
2y=4-3
2y=1
Divide both sides by 2
2y/2=1/2
y=1/2
Answer:
x > -2.5
Step-by-step explanation:
1) 5.1 (3 + 2.2x) > -14.25 - 6 (1.7x + 4)
2) 15.3 + 11.22x > -14.25 - 10.2x - 24
3) 15.3 + 11.22x > -38.25 - 10.2x
4) 11.22x + 10.2x > -38.25 - 15.3
5) 21.42x > -53.55
6) x > -2.5
Alternate forms
x > -5/2x or x > -2 1/2
