The answer is x = -2 you move the all x to one side and all numbers to the other side. then divide to find x
Answer:
$ 9 each bottle
Step-by-step explanation:
1 crate = $45
1 crate = 25 bottles
if we want to earn $180 per crate , we have to add this value to the $45
45 + 180 = 225
if the value of the box to win $180 is $225, we have to divide the new value by 25 (number of bottles) and we will have what we will have to charge each bottle
225/25 = 9
we have to charge $ 9 each bottle to earn $ 180 per crate
x in (-oo:+oo)
h/j = 15 // - 15
h/j-15 = 0
h*j^-1-15 = 0
x należy do R

Answer:
El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.
Step-by-step explanation:
- First, the data must be taken into account to create the equations:
- Where:
X = Number of polio vaccines and Y = Number of measles vaccines.
- 4X + 2Y = 184; (Equation 2)
Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.
- We clear the variable that we want to find in each equation:
- Y = 60 - X; (And we call it equation 3)
- Y = (184-4X) / 2; (And we call it equation 4)
- Now both equations are equalized in terms of the same variable:
- Then X is cleared to find its value:
- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values of Y
- Finally, both values are used to see if equation 2 gives us the correct data:
- The answer is given:
Dr. Potter gave 32 polio and 28 measles vaccines.
