Answer:
I'm pretty sure the answer to number one is 12g.
Step-by-step explanation:
To combine like terms, you combine all of the same variables.
For example, if you have 5x+7y+5x, you would combine like terms to make 10x+7x.
So for your first problem, we know that the combined like term is 15g. We know that one of the numbers combined was 3g. With that knowledge, you can subtract 15g-3g and get 12g.
I hope this makes sense, and helps you answer your other questions!
By solving the given equation 20 + 0.44x = 19 + 1.69x we get x=0.8.
<h3>What is meant by an equation?</h3>
When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. For instance, an equation in French is described as having one or more variables, whereas in English, an equation is any properly written formula that consists of two expressions linked by the equals sign.
Determine which values of the variables result in the equality to be true in order to solve an equation with variables. The values of the variables that must fulfill the equality to constitute the answer are known as the unknowns, together with the variables for which the equation must be solved.
Given,
20 + 0.44x = 19 + 1.69x
20-19=1.69x-0.44x
1=1.25x
x=0.8
Therefore, by solving the given equation 20 + 0.44x = 19 + 1.69x we get x=0.8.

Answer:
No extra pieces.
Step-by-step explanation:
Given:
Total number of foot board = 3
Equally divided into = 1/2
Question asked:
How many extra pieces will I have = ?
Solution:
By dividing 3 by 1/2 we can find the extra pieces.
= 
= 
= 
Since, the remainder is zero, thus there is no any extra pieces I have.
