Answer:
The smaller addend is subtracted from the bigger addend
Step-by-step explanation:
Represent the two numbers with a and b such that a > b
So, the mathematical representation will be
Open the bracket
<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>
<em></em>
<em>Take for instance; a = 6 and b = 4</em>
<em>This gives</em>

To find the volume of the following Firewood, we would do this:
4 * 4 * 8 = 128 cubic feet
Therefore, the volume of the firewood is 128 cubic feet.
Make sure to mark as brainiest.
Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
Answer:
D
Step-by-step explanation:
We need to convert these words into mathematical expressions:
- "Twenty-two less than a number"; "less than" indicates that we need to use subtraction, and since it's "twenty-two less than", we have: -22. Let's say the "number" is q. Then, we have -22 of q, which is q - 22.
- "is twenty-four"; "is" in math always means "equal", so we need an equal sign with 24 next to it: = 24
Put this altogether:
q - 22 = 24
The answer is thus D.
