2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
Answer:
$1880.48 to the nearest cent.
Step-by-step explanation:
Total after n years = P(1 + r)^n where P = initial deposit, r = the rate as a fraction.
4 5/8 % = 0.04625.
Here the total after 5 years = 1500(1 + 0.04625)^5
= $1880.48 to the nearest cent.
The second number after the decimal is the hundredths place. To round to that place, you look at the number after it. In this case 6 is the hundredths place and 5 is the number after it. If the number after it is 5 or higher, the hundredths place number increases by 1, if it is less than 5 the hundredths place number doesn't change. So the answer is 8.47.
The answer is 0.73 hope it helps
