Answer:
120= 8n
Step-by-step explanation:
You would have to divide by eight on both sides
120 ÷ 8
this is so you can find that once divided
120 ÷8 = 15
therefore n= 15
8×15 = 120
sorry if it's not too clear
Answer:
72
Step-by-step explanation:
The two digit number can be represented by xy, where x and y must add to 9 and x - y must subtract to 5. Make a system of equations.
Use the elimination method and add the terms from top to bottom like so. The y and -y cancel out.
2x = 14
Divide both sides by 2.
x = 7
Substitute 7 for x into the first equation (either eqn would work).
(7) + y = 9
Subtract 7 from both sides.
y = 2
Combine these two together; xy --> (7)(2) --> 72.
The number is 72.

The shown decimal goes on for 200 digits.
And it cannot be put into fraction form, meaning it is irrational.

Answer:
40liters
Step-by-step explanation:
Given data
1/5 full holds 16 liters
1/2 full barrel will hold???
Let 1/2 full barrel hold x liters
1/5 holds 16 liters
1/2 will hold x
cross multtiply
1/2*16= x/5
8= x/5
x= 8*5
x= 40 liters
Hence 1/2 full will hold 40liters
