Answer: 8
Step-by-step explanation: To find the least common multiple or (lcm) of 4 and 8, let's begin by listing the first few multiples of each number.
<em><u>Multiples of 4</u></em>
1 × 4 ≈ 4
2 × 4 ≈ 8
3 × 4 ≈ 12
4 × 4 ≈ 16
Notice that we skipped 0 × 6 in our list of multiples and this is because 0 × 4 is equal to 0 and our least common multiple can't be 0.
Now, let's list the multiples of 8. When listing the multiples of 8, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.
<u><em>Multiples for 8</em></u>
1 × 8 = 8 ← is a multiple of 4
Notice that we can stop here because all other multiples that we find will be greater than 8. Therefore, the least common multiple or (lcm) of 4 and 8 is 8.
Answer:
(Price x 0.20) + price
Step-by-step explanation:
To find a certain percentage of something, move the decimal on the percent 2 places to the left and multiply that by the original number
If something is marked up by a certain price, that means you’re adding to it so you just have to add whatever 20% of the item is to the original cost
If your writing the equation it would be e subtracted by 5 equals 18 so it would look like e-5=18
60x+80=100x combine like terms
80=100x-60x or 40x divide to get x by itself
80/40=40x/40
20=x
