False ?
I am not sure, I took the test and I don’t remember the answer
Answer:
Step-by-step explanation:
Plug it in
y = 2/3(24 - -10/3) + 5(-10/3)y
y = 2/3 (82/3) + 5(-10/3)y
y = 164/9 - 50/3y
because there are “y” values on both sides, they cancel out, leaving a number to equal another number. this does not make any sense. therefore, there is no solution to this equation when x = -10/3.
Answer:

Step-by-step explanation:
Given:
The system of equations given are:

If an equation is multiplied by a number throughout, then the equation remains the same by multiplication property of equality. The multiplication property of equality says that if both sides of the equation is multiplied by the same number, then the new equation is equivalent to the previous equation.
For example: If
is multiplied by 2 on both sides, then the new equation will be
which is equivalent to
.
So, from among all the choices given, the first choice represents the above mentioned property. The equation
is multiplied by 3 on both sides. So, the equation
is equivalent to
.
The second equation
has not been changed. So, the equivalent system of equations to the given system is:

The total cost would be 26.50
