2(6y − 3) = 20 + 6y

Use the distributive property, which states a(b - c) = ab - ac

We should get:

2*6y - 2*3 = 20 + 6y

Which can be simplified to:

12y - 6 = 20 + 6y

That means the mistake was in step 2. The student didn't multiply the numbers and instead added the numbers.

Your answer is: <span>Step 2: 12y-6=20+6y</span>

1)

\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+r\right)^{t}&#10;\quad &#10;\begin{cases}&#10;A=\textit{compounded amount}\\&#10;P=\textit{original amount deposited}\to &\$600\\&#10;r=rate\to 1.6\%\to \frac{1.6}{100}\to &0.016\\&#10;t=years\to &2&#10;\end{cases}&#10;\\\\\\&#10;A=600\left(1+0.016\right)^{2}

3)

\bf V(t)=1350(1.017)^t\implies &#10;\begin{array}{llllll}&#10;V(t)&=&1350(&1 +& 0.017&)^t\\&#10;A&=&P(&1+&\boxed{r}&)^t&#10;\end{array}

notice the rate "r"... now, is in decimal format, as you saw on 1) is just r/100 so 1.6% was really 1.6/100 or 0.016  anyhow

to get the percentage form, just multiply it by 100

The sum of 2 numbers is 150.One number is 12 more than the other number.What is the smaller number?​
anygoal [31]
The smaller number is 63 I think.

I think this because 150/2 is 75

75-12=63

the small number would be 63

the larger number just in case u need it btw is 87 I think


hope this helps
