Answer: 30 miles
Step-by-step explanation:
45/6 = 7.5 miles per minute
7.5 x 4 = 30 miles per minute
First multiply, so 42 x 39, which equals 1,638, then estimate, round 42 to 40, and 39 to 40, and do 40 x 40 = 1,600 which is close to your answer, so good.
Answer:
m = 3.53972077085
Step-by-step explanation:
-3 ×
- 3 = -27
Subtracting -3 from both sides of the equation gives;
-3 ×
= -24
Dividing by -3 on both sides of the equation gives;
= 8
Let 2m - 5 = x
xloge = 3log2
x =
= 2.0794415417
So,
2m - 5 = 2.0794415417
2m = 2.0794415417 + 5
2m = 7.0794415417
Dividing by 2 on both sides of the equation gives:
m = 3.53972077085
The value of the car is $13,510.75 after three years.
