Answer: The correct answer is Choice C.
Step-by-step explanation: In order to solve this problem you need to look at the equation’s parts.
The first part is multiplying 5 by the contents of the parenthesis. So, 5(2x-2) equals 10x - 10. Now, but the equation together and simplify it:
10x - 10 + 10x =
20x - 10
rules to find :- 1 All non zeroes number are significant
2 if zero proceeding the decimal point also work as non zero figure
3 zero are following the decimal point and proceeding the first non zero digit
4 Zero in between 2 non zero digits are also significant
5 if 1 zero follow the decimal point
790 :- 2 significant figures
0.0391 :- 3 significant figures ( follow 3 rule)
81.05 :- 4 significant figures ( rule 4)
0.000001 :- 1 significant figure
8546 :- 4 significant figures
79.0 :- 3 significant ( rule 5)
Answer:
<h2><u>7</u>x - <u>7</u>y + <u>21</u> </h2>
Step-by-step explanation:
7(x - y + 3)
=> 7 × x - 7 × y + 7 × 3
=> <u>7</u>x - <u>7</u>y + <u>21</u>
Answer:

Answer:
John have to pay back $23,327.50 at the end of two years
Step-by-step explanation:
Simple Interest (I) = (PRT) ÷ 100
where P = Principal, R = Rate, T= Time
I = ($150500 × 7.75 × 2) ÷ 100
I = ($2332750) ÷ 100
I = $23,327.50
