Step-by-step explanation:
72302 = 9*8000 + 0*400 + 15*20 + 2
The digits are 9 (four dots and one line), 0 (there is a special symbol for this), 15 (three lines) and 2 (two dots).
-19=5(×+9)
-19=5×+45
-19-45=5×
-64=5×
-64/5=×
×=-64/5
If you would like to know the average speed for the round trip, you can calculate this using the following steps:
5 hours + 6.5 hours = 11.5 hours
240 miles * 2 = 480 miles
11.5 hours ... 480 miles
1 hour ... x miles = ?
11.5 * x = 480 * 1
11.5 * x = 480 /11.5
x = 480 / 11.5
x = 41.74 miles per hour
The correct result would be 41.74 miles per hour.
Answer:
no solution
Step-by-step explanation:
first you have expand the equation and so you will get
18x-12=18x+2
after you cancel 18x on both sides and so you will get
-12=2
and since that equation is false you will get
no solution
N+d=33
5n+10d=235
n=-d+33
-5d+165+10d=235
5d=70
d=14
n=19
