Answer:
n = 20
Step-by-step explanation:
The problem says that there is a number (n) that is added to 1/5 of itself ((1/5)*n), and that sums is equal to 24, so the equation that models the problem is:
n + (1/5)*n = 24
Taking the least common multiple in the left side, which is 5:
(5n + n)/5 = 24
6n = 120
n = 120/6
n = 20
Hey! When you ask a question there is a math equation option. Use that to scan the problem and it will give you your answer.
Answer:
40 - 3*(3 + 8) = 7
Step-by-step explanation:
Sneaky!!!
40 - 3(3 + 8) = 7
40 - 3 * 11 = 7
40 - 33 = 7
which is the solution.
I'm not sure what operation you're using but for example, subtraction and addition are inverse operations and division and multiplication are inverse operations
You can do any problem first because they will all come out to be the same answer. The property that I am going to be using for all of them is commutative property of multiplication. -5*1=-5 is the first step you could do. -5*4=-20, it doesn't matter is you skip a number or not it will be okay. -20*11=-220. You can start with any one and the answer will still be -220.
