4(x-2) is different because if you distribute the expression it would be 4x-8 and the rest of the expressions are simplified to 4x-2
Here's an example of %
20% = 0.2
2% = 0.02
when multiplying with decimals in place you always add up the two periods, 155.8 × 0.2 = 31.16
since the dot is one over for both you add 1 + 1 which equals 2, then when you get 31.16 you move over 2 decimal points, making it 31.16
btw the answer is when you subtract 31.16 from 155.80 which would be 124.64$ for your final cost.
He hold account for 5 years or 5 months. Depending on 3% per year or 3% per month
N(20/100)(20/100)=20
400n/10000=20
400n=200000
n=500
Answer:
number 5 is 15x
Step-by-step explanation:
what you have to do is just add basically. The ones with exponents you do the usual with those as well. Ignore the X's and when you solve the problem add the x beside the number.
