Monday : x
tuesday : 3x
wednesday : 3x - 20 = 40
thursday: 20
3x - 20 = 40
3x = 40 + 20
3x = 60
x = 60/3
x = 20
monday : 20 minutes
tuesday : 3x....3(20) = 60 minutes
wednesday : 40 minutes
thursday: 20
for a total of : 140 minutes <===
Answer:
13.05
Step-by-step explanation:
Answer:
61 cubic meters
Step-by-step explanation:
1) Find the volume of the cube where s=4
1a) V= s*s*s
1b) Insert in side length
V=4*4*4
1c) solve
V=64 cubic meters
2) Find volume of 2nd cube by repeating same steps where s=5
2a) V=125 cubic meters
3) Subtract to find difference
3a) 125-64
3b) Solve: 61 cubic meters
If you were to add a and 50 it would be 50a
