The 1.4% interest rate given is an annual rate. So, the daily interest rate is 1/365 of that value. The first day's interest is 1/365 of 1.4% of $720:

1/365 × 0.014 × $720 ≈ $0.0276 ≈ $0.03 . . . . first day's interest

3x + 2x + 7 = 32 <br> x = ?

Answer:

x = 5

Step-by-step explanation:

Hello!

For this equation, we start by combining like terms. Since we have two terms with the same variable, we are able to add them together:

3x + 2x + 7 = 32

5x + 7 = 32

As you can see, we added 3x and 2x together.

Now, since we are aiming to get x by itself, we need to subtract 7, from both sides:

5x + 7 = 32

5x = 25

Finally, we divide the 5 attached onto the x by itself, which will leave the x alone on one side:

5x = 25

x = 5

Again, we divided on both sides.

And, there you have it!

x = 5

Hope I helped!
