Answer:
Hot dogs sold: 44
Sodas sold: 132
Step-by-step explanation:
This is is a problem of a system of two equations with two unknowns. This can be solved in multiple ways (the substitution method, the elimination method, the equalization method, the graphic method...) . I will resolve it using the equalization method that is a little bit more practical from my point of view.
First, we have to determine the system by the data we are given:
Where:
Secondly, we are going to isolate any variable from both equations. I chose to isolate Y.
Thirdly, we equalizate both equations.
So we get:
Then we isolate X.
So now we know that the number of hot dogs sold was 44! If the sodas sold were three times the number of hot dogs sold, then we know that there were 132 sodas sold at the hockey game!
Answer:
Kendra is watching over 5 children. She wants to be sure that they each have an even number of apple slices. There are 35 apple slices total. She wants to take 35 and put it equally into 5 groups.
Your equation would be 5s=35, where s would be the total amount of apple slices on each plate.
To solve this equation you would divide both sides by 5 to get 7. s=7 (35/5=7)
Each quintuplet would be 7 apple slices.
Hope this helps ;)

The solution for the given equation is a = -5.

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
To find the solution to the given equation:
Negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3)) can be expressed mathematically as follows.
- - (5 - (a + 1)) = 9 - (5 - (2a - 3))
Using the principle of PEMDAS, all the parenthesis values are first solved.
- - (5 - a - 1) = 9 - (5 - 2a + 3)
- -5 + a + 1 = 9 - 5 + 2a - 3
Collect like terms:
- -5 + 1 - 9 + 5 + 3 = 2a - a
- -5 = a
That is a = -5.
Therefore, the solution for the given equation is a = -5.
