1. Divide both sides by 2
2. Add 16 to each side
Answer x > -2
Answer:
if I'm solving for x, then its 2
(I think)
So, he runs 1.5 then adds 0.5 every day,
1.5
(1.5+0.5)+1.5=x
(2.0+0.5)+x=z
2.5+0.5+z=y
etc.
Why, they want to know the total distance he runs, so thats why you add x,y,z to the end, and you add 2.0+0.5 because he adds 0.5 every dat Plus the other day's miles jogged
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.
3.25 is the answer
Step-by-step explanation:
you would add them as decimals
