Answer:
4x
Step-by-step explanation:
Answer:
The number is 42.
Step-by-step explanation:
Let x be the unknown number.
"two less than a number" is x - 2
Quotient means the result of a division.
(x - 2)/5 = 8
Multiply both sides by 5.
x - 2 = 40
Add 2 to both sides.
x = 42
Answer: The number is 42.
Check.
Start with 42. 2 less than 42 is 40. The quotient of 40 and 5 is 40/5 which is 8. The answer is correct.
11*2 = 22 (calculating the diameter)
Using πD for the area:
π * 22 = 22π
Getting 3/4 of the area because the dog can not move past the corners of the garage;
22π * 3/4 = 16.5π
Getting the answer in feet^2:
16.5 * 3.14 = 51.84 feet^2
Hope this helps! :)
Answer:
3 7/9
Step-by-step explanation:
we have
3.77777... -----> is a repeating decimal
Let
x=3.7...
so
10x=37.7...
10x-x=37.7...-3.7...
9x=34
x=34/9
Convert to mixed number
34/9=(27/9)+((7/9)=3+(7/9)=3 7/9
