Option B:
is the value of y
Explanation:
It is given that "Two times x is 8 more than y". Writing it as expression, we have,

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

To find the value of y, let us solve the two equations using substitution method.
From the equation
, let us find the value of x.



Now, substituting
in the equation
, we get,





Thus, the value of y is 
If she deposited $600 and had $621.60 after four years, then she earned: $621.60 - $600 = $21.60 in four years. It means in one year she earned $21.60 ÷ 4 = $5.40. Now we have to find out how many percent of $600 is $5.40:
$5.40 = x% from $600
5.4 = x/100 * 600
5.4 = 600x/100 / * 100 (both sides)
540 = 600x / ÷ 600 (both sides)
x = 0.9
So the interest rate was 0.9% annually.
Now we have to find out how much is 0.9% from $1100:
$1100 * 0.9% =
= 1100 * 9/1009 =
= 9900/1000 =
= 9.9
It means in one year she would earn $9.90. After 7 years she would earn $9.90 * 7 = $69.30, so she would have in her account:
$1100 + $69.30 = <u>$1169.30</u>
Answer:The answer is Equal.
Step-by-step explanation:First you need to add A and 2A together. that equals 3a. Since 3 is left , it could be -1 and 4 because it would equal the same thing hope this helped :)
The answer is 7/4 I added my work there sorry if it’s kinda messy
Answer: It equals 8.
