Answer: what do you mean
Step-by-step explanation:
Answer:
2.64
Step-by-step explanation:
x² + 6= 13
x² = 13-6
x²= 7
x = square root of 7
x = 2.64
Answer:
x = 12
Step-by-step explanation:
Equation can be used to find x is 60/55 + 60+x = 2.75
The time of going to rink is 2.75
We know,
speed = distance/time
⇒ Time = distance / speed
<h3>How to solve?</h3>
(1) Way to rink
Given :
Distance = 60 miles
Speed = 55 miles per hours,
⇒ Time taken by him = Distance / speed = 60/55 hours
(2) Way to home
Given : Distance = 60 miles
Let Speed be x,
⇒ Time taken by him = distance/speed = 60/x hours
Total time taken = 60/55 + 60+x
According to Question, Total time = 2.75 hours,
Thus, 60/55 + 60+x = 2.75 is the required equation.

Answer:
$12000 at 5% for 8 years
Step-by-step explanation:
The amount in an account earning continuous interest is given by ...
A = Pe^(rt)
Then the interest earned is ...
I = P(e^(rt) -1)
For the two accounts, the interest earned is ...
I = 12000(e^(.05·8) -1) = 12000(0.491825) = 5901.90
I = 9000(e^(0.065·7) -1) = 9000(0.576173) = 5185.56
The $12000 account earns more interest, primarily because of the larger amount invested.
