Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. To see this process in action, check out this tutorial!

5y-3y+1=7<br><br> solve for y

Juli2301 [7.4K]

Answer:

y=3

Step-by-step explanation:

Let's solve your equation step-by-step.

5y−3y+1=7

Step 1: Simplify both sides of the equation.

5y−3y+1=7

5y+−3y+1=7

(5y+−3y)+(1)=7(Combine Like Terms)

2y+1=7

Step 2: Subtract 1 from both sides.

2y+1−1=7−1

2y=6

Step 3: Divide both sides by 2.

2y /2 = 6 /2

y=3

Joey invest $900 at 4% simple interest for 2 years but he wants to know how much money he will have after only 18 months. Determ

malfutka [58]

Well, bearing in mind that, a year has 12 months, so 18 months is really just 18/12 of a year, or 3/2 a year, then

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to \frac{18}{12}\to &\frac{3}{2}
\end{cases}
\\\\\\
A=900\left( 1+0.04\cdot \frac{3}{2} \right)$
