Answer:
3rd choice
Step-by-step explanation:
The answer is the 3rd choice.
x cannot be 3 and 5 at the same time.
x = 3
x = 5
Subtract the first equation from the second equation.
x - x = 5 - 3
0 = 2
Since 0 = 2 is a false statement, there is no solution.
Answer: 3rd choice
The answer should be around 314.159. The formula is v=pi*r2*h. Plug in the numbers and its v=pi*25*4. That is 25*4 which is 100. Then *pi and it should be it.
It might be 36

Start by creating an equation. You’ll need a variable to represent what is earned per week, for example x.
So,
420=60+9x
(Since he already has 60)
Subtract the 60 from 420 to begin isolating the variable
This gives you
360=9x
Divide both sides by 9 to completely isolate the variable
This gives you
40=x
So, he needs to save up $40 each week
