Answer:
<em>A</em>
Step-by-step explanation:
My reasoning is because right above the question it says "Given: DEF" meaning that you would go in order of <em>DEF</em><em>.</em>
<em>So</em><em>,</em> looking at the triangle, <em><u>D would be 10, E would be 13, and F would be 15.</u></em>
2,523 is your investment for 15%
1,611 will be your investment for the 6%
So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.
Answer:
A rational number is a number that can be express as the ratio of two integers.
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).
Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:


This can be represented as:

Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:





Subtract the spendings from the total to get amount left


Collect Like Terms


Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
