Answer:
24
Step-by-step explanation:
The LCM or least common multiple of these numbers is 24
To get 24, you list all the multiple of these numbers until they all share at least one
So
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>
6, 12, 18, <u>24</u>
8, 16, <u>24</u>
They all share 24 so this is the LCM

For 3x + 12 + x, do like terms:
4x + 12
For 4(3 + x), multiply
12 + 4x
They are both the same, just written in different ways. One is adding like terms and the other is multiplying with parentheses. Even though it may be switched around, it is still the same.
Hope this helps :)
Answer:
1. 7¹⁰
2. 9⁸
Step-by-step explanation:
1. 7 = 7¹
Hence, using the rules of indices..... you would add the exponents when numbers that have the same base are multiplied together.
7⁹⁺¹ = 7¹⁰
2. Add exponents
9²⁺⁶ = 9⁸
The price after tax is £253.87 so to find the original price you have to deduct 6% but first you need to find 6%.
Easiest way to find 6% is by finding 10% or 2% or 1% / whatever you find easiest. For me it would be 1%
If you find 1 % you would then multiple it by 6 to give you 6%
10% is £25.38 (move the decimals 1 unit)
1% is £2.54 (move decimals 2 units)
Always round up
£2.54 X 6 = £15.24
£253.87 - £15.24 = £238.63
