The first question's answer is the second choice. The second question's answer is the first choice. The third question's answer is the second choice.
Answer:
is this by any chance about simultaneous equations? If so,
Step-by-step explanation:
Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.
Step 2 is telling us to write equations with x and y.
For example,
7x + 5y = 12
7x - 2y = 9
This may not be accurate but it is an equation.
Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.
For step 5, im not really sure.
hope this helps though???
Answer: Yes
Step-by-step explanation:
Letter a I think is correct because if it's 2.5 per game plus 5 dollars per month then the equation is 2.5v+5 and for 4 games it is 2.5(4)+5 which equals 15 and 5(4) is 20 so letter a is corrext correct
