Answer:
the equation has no solution
Step-by-step explanation:
Given
7 + 2x = 2(x - 1) + 4 ← distribute and simplify the right side
7 + 2x = 2x - 2 + 4
7 + 2x = 2x + 2 ( subtract 2x from both sides )
7 = 2 ← not possible
This indicates that the equation has no solution
Answer:
answer is +4...
Step-by-step explanation:
when x=6, the expression becomes
2(6)^2+ 4-5
2(36)+(-1)
72-1=71
therefore 71+4 gives 75
Answer:
choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec
Step-by-step explanation:
To find average speed between 3 and 8 seconds, find the total distance traveled during that time.
650 meters at 3 seconds
to 375 meters at 8 seconds
then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec
