The perimeter of a rectangle is 36 feet. The length is 2 feet more than 3 times the width. What are the dimensions of the rectangle?

Step-by-step explanation:

The perimeter (P) of a rectangle is equal to the sum of twice the length and twice the width.

For this problem, let x be the width.

Then because the length is 2 less than 3 times the width

The length is 3x - 2

Therefore, P = 2x + (2)(3x - 2) = 36

Solving this for x gives:

2x + 6x - 4 = 36

8x - 4 = 36

8x = 40

x = 5

Therefore, the width = x = 5 feet

And the length = 3x - 2 = (3)(5) - 2 = 13 feet

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
