Answer:

(3, 6) or x = 3 and y = 6

Step-by-step explanation:

у = 2x, x + y = 9 (using substitution)

x + 2x = 9

3x = 9

x = 3

y = 2x

y = 2(3)

y = 6

What is 4 minus 1 5/12
klasskru [66]

Answer: 2 and 7/12

Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.

Notice however that we can't subtract 0/12 - 5/12.

So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.

Now we have 3 and 12/12 - 1 and 5/12.

Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.

So 5 - 1 and 5/12 is 2 and 7/12.

Rachel deposited $5,960.32 into a savings account with an interest rate of 4.2% compounded twice a year. About how long will it
ahrayia [7]
You need the compound interest formula solved for time:
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (9,000 / 5,960.32) / 2 * log (1 + .042/2)
Years = log ( <span> <span> <span> 1.509986041</span></span></span>) / 2 * log (1.021)
Years =  0.1789729325 / 2 * 0.0090257420869
Years =  <span> <span> </span></span><span><span><span>0.1789729325 / 0.0180514842 </span> </span> </span>
<span><span><span>Years =  9.9145826746 </span> </span> </span>
the answer is "d"
