Answer:
$500.1
Step-by-step explanation:
Step one:
principal= $500
rate= 3%
time 8 months
Required
The final amount
Step two;
simple interest= PRT/100
SI= (500*0.03*8/12)/100
SI=10/100
SI=0.1
The final amount is
Amount= 500+0.1
Amount= $500.1
Answer:
80
Step-by-step explanation:
every triangle adds up to 180 sort of, in this case, turn 4 into 40. 40+20=60 so add 80 to be 180!!!
The Greatest Common Factor (GCF) is very important when factoring. Later on, you will forget to pull out a GCF and the answer will be wrong. Always look for a GCF before doing anything.
Let's try factoring these:
a.) 
The greatest common factor of this expression is 9, because it is the maximum number that both can go into. Let's solve.

This is the simplest this expression can get. This would be your final answer. Let's try the other one.
b.) 
The GCF of this one is 12. Let's simplify it.

This is also the simplest you can get it. You can do nothing further. So, your final answers are:
a.) 
b.) 
Steps?
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
Answer:
A. a = 2s - b -c
Step-by-step explanation:
Rearrange the equation in a way that you have only a on one side. When solving equations you can add, subtract, multiply or divide by the same number/variable/expression on the both sides.

Multiply by 2 to get rid of the fraction.

On the right side the 2 cancels out:

On the right side next to a are still b and c. But we want a alone. Subtract b.

b - b on right side gives 0.

The step above is usually skipped, because number + 0 = number.

Next to a there is still c. Subtract c.

c - c on the left is 0.

So our answer is:

It can be rewritten to (change sides):

And s · 2 can be rewritten to 2s:
