Answer:
1 : 6
Step-by-step explanation:
Calculate the perimeter
perimeter = 2(3x + 5) + 2(6x + 10) = 6x + 10 + 12x + 20 = 18x + 30
perimeter = 18x + 30 ← take out a common factor of 6 from both terms
= 6(3x + 5)
ratio of width : perimeter
= 1(3x + 5) : 6(3x + 5) ← divide both parts by (x + 5)
= 1 : 6
Answer:
3 x 0.8 = 2.4
Step-by-step explanation:
3 × ? = 24 tenths
3 x ? = 2.4
? = 0.8
3 x 0.8 = 2.4
Answer:

Step-by-step explanation:

2) Simplify -16 - 40 to -56.

3) Divide both sides by -8.

4) Two negative numbers makes a positive.

5) Simplify 56/8 to to 7.

Answer:
The value of n is 11 feet.
Step-by-step explanation:
Given that the area of rectangle from is A = length×width so we have to substitute the variables into the formula in order to find n :

Let area = 33,
Let length = n,
Let width = 3,
