Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61
Answer is YES
Because
2 ones = 2 x 1 = 2 and 20 tenths = 20 x 0.1 = 2
Assuming the price of the pool does not change, then
Additional interest required is 4500-3750=750
using
I=Pit, we set up equation
750=3750*0.055*t
Solve for t
t=750/(3750*0.055)=3.64 years.
So will need to wait 3.64 years, or rounded up to 4 years.
Answer:
x=36/11=3.2727...
Step-by-step explanation:
The solution can be found by solving for x.
First, combine like terms and simplify each side of the equation.
Second, use inverse operations to move terms across the equal sign.
