An equation does not always have a solution. Sometimes, an equation can have a variable that does not equal the remaining value on the other side. For example, root negative x could never equal a number squared.
√-x ≠ 14²
This equation cannot have a solution because you can't square any number to get a negative solution. Therefore, x= no solution.
Answer:
1. x=17.5
2. x=77
Step-by-step explanation:
1. -x=-3x+35
=2x=35
x=17.5
2. -x/7+8=-3
=-x/7=-11
=-x=-77
x=77
Answer:
E would most likely stand for exponent
Step-by-step explanation:
Answer: 18mph
Step-by-step explanation:
Given data
total distance driven = 396 miles
time driven = 8 am Tuesday to 5 pm Wednesday
total time driven in hours = 33 hours
lunch break time = 30 min Tuesday + 30 min Wednesday
= 60 min
= 1 hour
sleep time = 7 pm Tuesday to 5 am Wednesday
= 10 hours
solution:
To find the average speed,
we are given total time driven = 33hrs.
lunch + rest time = 10hrs + 1hr
= 11hrs
total time travelled =drive time - rest + lunch time
= 33 - 11
= 22hrs
therefore;
average speed = distance / time traveled.
average speed = 396 / 22
average speed = 18 mph
Answer:
(3,12)
Step-by-step explanation:
you would put the 12 as y then 3×3=9+6=15 and 12 doesn't equal 15
