Answer: 4,320 inches cubed.
Step-by-step explanation:
step 1----- Volume of 1 canvas box
Volume of solid for a rectangular box = Length x width xHeight
where Length= 12inches,
Width= 10 inches
Height= 12 inches
Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed
Step 2== Volume of 3 canvas boxes
1 canvas box = 1440 inches cubed
therefore 3 canvas boxes =
1440 x 3= 4320 inches cubed.
The answer is: " -21 " .
__________________________________________
We are asked to solve for: "6t" ; which is: "6 * t" .
__________________________________________
Given: 3t − 7 = 5t ; Solve for "t" ; then solve for "6t" ;
3t − 7 = 5t ; Subtract "3t" from each side of the equation;
____________________________________________
3t − 7 − 3t = 5t − 3t ;
to get: -7 = 2t ;
Divide EACH side of the equation by "2" ; to isolate "t" on one side of the equation; and to solve for "t" ;
-7/2 = 2t / 2 ;
-3.5 = t ; ↔ t = - 3.5 ;
____________________________________________
Now, solve for "6t" ;
6 t = 6*(-3.5) = - 21 . The answer is: " -21 " .

Answer:
you need to simplify them like 2n+6 simplifird if 2.(n+3)
Step-by-step explanation:
Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
