Answer:
C. 
Step-by-step explanation:
Given the two equations:
To find:
The correct option when value of y is substituted to 2nd equation using the 1st equation.
Solution:
First of all, let us learn about the substitution method.
Substitution method is the method to provide solutions to two variables when we have two equations and two variables.
In substitution method, we find the value of one variable in terms of the other variable and put this value in the other equation.
Now, the other equation becomes only single variable and then we solve for the variable's value.
Here, we have two equations and value of one varible is:
Let us put value of y in 2nd equation:
So, the correct answer is option C.
Answer:
x=3
Step-by-step explanation:
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total amount to spend = $55
Amount of food and drinks purchased = $14.25
Amount put on gaming card = $(55 - 14.25) = $40.75
Cost per game = $1.25
Number of games (g) he can play
Number of games g:
Amount put on gaming card / cost per game
= $40.75 / $1.25
= 32.6 games
g ≤ 32

Answer:</h2><h2><em><u>
8x^3 + 3x^2 - 5x + 4 is the answer.</u></em></h2>
Step-by-step explanation:
(6x^3 + 3x² + 3) + (2x^3 - 5x + 1)
6x^3 + 2x^3 = 8x^3
3x^2 + 0 = 3x^2
-5x + 0 = -5x
3 + 1 = 4
8x^3 + 3x^2 - 5x + 4 is the answer because you have to put all the terms that were solved together. This will lead to 8x^3 + 3x^2 - 5x + 4. And, standard form is ax^2 + bx + c. So, 8x^3 + 3x^2 - 5x + 4 is the answer.
<em><u>8x^3 + 3x^2 - 5x + 4</u></em>
