Box volume = height * width * length. In this problem we want the length, so we solve the given equation for length:
720 in^3
length = -------------------- = 12 in
(15 in)(4 in)
The box is 12 inches long.
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours
Answer:
there is a feature on this app where u can take a picture and it will give u the answer. i would suggest trying that because it is quite useful
-1. Plug in -3 for x which makes 9-10 so -1
The answer for this problem would be 7x+6
Let's solve this problem step-by-step.
4x−3+3x+9
=4x+−3+3x+9
Step 1: Combine Like Terms.
=4x+−3+3x+9
=(4x+3x)+(−3+9)
So, the answer for this problem would be 7x+6.
