The first thing you do is subtract negative 5 on both side because we want to get x by itself.
Then we subtract 12 -5 which get us 7.
So, the solution is x=7.
And that how you solve the equation.

A person invests $4000 at 2% interest compounded annually for 4 years and then invests the balance (the $4000 plus the interest

\\\\\\
A=4000\left(1+\frac{0.02}{1}\right)^{1\cdot 4}\implies A=4000(1.02)^4\implies A\approx 4329.73$

then she turns around and grabs those 4329.73 and put them in an account getting 8% APR I assume, so is annual compounding, for 7 years.

\quad 
\begin{cases}

A=4329.73\left(1+\frac{0.08}{1}\right)^{1\cdot 7}\implies A=4329.73(1.08)^7\\\\\\ A\approx 7420.396$

add both amounts, and that's her investment for the 11 years.

The automaker of your new car recommended an oil change following the 5,000 miles and then every 3,000 miles thereafter.if you p

Rus_ich [418]

Answer:

3 oil changes

Step-by-step explanation:

1. Find an equation that represents this word problem: 3000x + 5000 = y

Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.

2. Solve for x: 3000x + 5000 = 13000 3000x=8000

3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year
