Answer:
(a) $60 | (b) $660
Step-by-step explanation:
We can use the simple interest formula for this:

<em>I = interest amount</em>
<em>P = principal amount</em>
<em>r = interest rate (decimal form)</em>
<em>t = time (years)</em>
<em />
First, change 5% into its decimal form:
5% ->
-> 0.05
Next, plug in the values into the equation:


<em>The interest earned is $60. To find the total balance, just add the $600 back.</em>

The total interest earned is $60 and the total is $660.

The formula for area of a triangle is: 1/2 x base x height.
You are given the height of 4 and the area of 4.
Replace those in the formula and solve for x ( base)
4 = 1/2 x base x 4
Divide both sides by 4:
1 = 1/2 x base
Multiply both sides by 2:
2 = base
x = 2
Answer:
a = -3
Step-by-step explanation:
-2(a-3)=12
distribute the -2 to the terms in the paranthesis
-2a + 6 = 12
minus 6 both sides
-2a = 6
divide -2 both sides to isolate a
a = -3
