Answer:
B
Step-by-step explanation:
The <u>Elimination Method</u> is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.
- If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
- If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
When multoplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).
So, option B is not allowed (it is not allowed to multiply only one part of equation)
Answer:
B. 4.5c + 4 = 24
Step-by-step explanation:
T = cx + py is the equation you are given.
T = 24 because it is the total amount of money you can spend.
x = 4.5 because each phone case costs 4.50 dollars
p = 2 because you bought 2 pop sockets.
y = 2 because each pop socket costs 2 dollars.
There is no c because you don't know the number of phone cases you bought.
Now, we have to substitute the values into the equation:
24 = 4.5x + 2(2)
24 = 4.5x + 4
4.5x + 4 = 24 <--- This is your answer
Hope this helps!
Answer:
(This is a example since you don’t have anything to round to)
Example Answer if the radius is 4 - 50.24
Step-by-step explanation:
Example Radius : 4
Area : 3.14
We have the mulitiply 3.14 times The Example Radius 2 times because The diameter of a circle is 2 times its radius.
( 3.14 x 4 x 4) 50.24
If you know the diameter, it’s a half or 1/2 as large.
Therefore, if the radius was 4, it would be 50.24.
Youre welcome :)
The point is not a solution to the equation of the line.
Hope this helps!
