(3 x 3) + (8 x 2) = ?
Using the order of operations you do what is inside the parentheses first, so multiplying the numbers, and then you add the products together.

A savings bank invests $58,800 in municipal bonds and earns 12% per year on the investment. How much money is earned per year?

seraphim [82]

To find the answer we simply have to find 12% of 58,800. So to do that, we can multiply it by .12

58,800 • .12 = 7,056

So $7,056 is earned per year

3x - 2(2x - 5) = 2(x + 3) - 8

Answer:

x = 4

Step-by-step explanation:

Hello!

We can solve for x by expanding the parentheses and isolating x.

<h3>Solve for x</h3>

3x - 2(2x - 5) = 2(x + 3)-8
3x - 4x + 10 = 2x + 6 - 8
-x + 10 = 2x - 2
10 = 3x - 2
12 = 3x
x = 4

The value of x is 4.
