4 0

Answer:

Step-by-step explanation:

Since they are supplementary, it means the addition of both angles gives 180 degree.

x - 15 + 2x = 180\\3x = 180 + 15\\3x = 195\\x = \frac{195}{3} \\x = 65

Illusion [34]

Answer:

$448

Step-by-step explanation:

We can use the simple interest formula for this:

A = P (1 + rt)

<em>P = initial balance</em>

<em>r = annual interest rate</em>

<em>t = time</em>

<em />

First, change 4% into its decimal form:

4% -> \frac{4}{100} -> 0.04

Now, lets plug in the values:

A=400(1+(0.04)(3))

A=448

The total amount in the account after 3 years will be $448
