Average speed = (1/2) (beginning speed + ending speed)
= (1/2) ( 13 m/s + 30 m/s )
= (1/2) ( 43 m/s )
= 21.5 m/s
Hi There!
I believe the answer to the first box would be 9x. Then second box would then be 45. The first and second box would be 9x and 45 because there are 9 chairs in each row making the number of chairs total to 45 chairs. The third and final box would be x=5. The third box would equal 5 because when 9 is multiplied by 5, the answer of the equation equals 45.
I hope this helps!
Answer:
5/6
Step-by-step explanation:
50/60 simplifies down to 5/6 if you divide by 10. 5/6 can not be simplified down any further because then you'd have a decimal fraction which.
Answer:
x = 3/4
Step-by-step explanation:
It usually works well to collect terms first. (Add the coefficients of x.)
-4x +x = -9/4
(-4+1)x = -9/4
-3x = -9/4 . . . . . . equation with terms collected
Now, you can divide by the coefficient of x. Here, it can be useful to consider this to be the same as multiplying by the inverse of that coefficient, which inverse is -1/3.
(-1/3)(-3x) = (-1/3)(-9/4) . . . . . multiply both sides by -1/3
x = 3/4 . . . . . simplify
