Step-by-step explanation:
<u><em>The question in English is</em></u>
Expressed in algebraic language.
Symbolically write the following expressions:
Three times a number:
Four times a number:
Two-thirds of a number
Let
n ----> the number
Part 1) we have
Three times a number:
we know that
The algebraic expression is equal to multiply 3 by the number n
so
Part 2) we have
Four times a number:
we know that
The algebraic expression is equal to multiply 4 by the number n
so
Part 3) we have
Two-thirds of a number
we know that
The algebraic expression is equal to multiply the fraction 2/3 by the number n
so
90000 is the nearest hundred thousand.
Answer:
assuming its an annual interest
Okay so 6 percent interest, the bank is paying you.
So with this it’s 6 percent of 1500 and add it to 1500.
You can always find 6 percent of 1500 and then add but here’s a short cut.
Your principle (beginning) balance is 1500.
That’s already 100 percent since thats yoru original value.
You then get added 6 percent interest.
We are jsut adding 6 percent to 100 percent so 106 percent.
Now we solve normally and you’d get the answer faster.
106 percent is 106/100 or 1 3/5 or 1.06
now we multiply
1500 * 1.06 = 1590
Your final balance would be 1590 after the 6 percent interest is added.
