2n + 28 = 96 [Two times n plus twenty-eight equals ninety-six.}
You need to get n by itself, so you first subtract 28 on both sides
2n + 28 - 28 = 96 - 28
2n = 68 Divide 2 on both sides
n = 34

Answer:
230 * (30/100) = 23 * 3 = 69
Step-by-step explanation:
This one can be learned by heart: "what is 30% of 230" means "calculate 30/100 times 230".
Question: What is the composite number?
Answer: A composite number is defined as a number that has divisors other than 1 and the number itself.
Step-by-step explanation: Start counting: 1, 2, 3, 4, 5, 6, .... so on. 1 is not a composite number because its sole divisor is 1. 2 is not a composite number because it has only two divisors, i.e., 1 and the number 2 itself.
Question 3 ⇒ 6.5 x 
If you move the decimal point in 6.5 seven spaces to the right you would get the number 65,000,000.
Question 4 ⇒ 3.99 x 
4.4 x
= 0.000044
3.99 x
= 0.00000399
2.6 x
= 260
1.85 x
= 1850
Question 5 ⇒ 0.0072
If you move the decimal point of 7.2 three spaces to the left. Your answer would be 0.0072, the third choice.
Question 6 ⇒ 
To get the answer to this problem you would count how many decimal places it would take to get your decimal point after 1, which would be 7. But, you want your exponent to be to the power of 10 not 1, so you would simply subtract 1 from 7 (7-1) which would give you 6. So your answer is
