<h2>Explanation:</h2><h2 />

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you assuming some things. First of all, for a two dimensional shape, the perimeter is defined as the distance around it. Suppose we have a rectangle whose dimensions are:

l=4x+9 \\ \\ w=2x-19 \\ \\ \\ l:Length \\ \\ w:Width \\ \\ \\ \text{So the perimeter is:} \\ \\ P=2l+2w \\ \\ P=2(4x+9)+2(x-19) \\ \\ P=8x+18+2x-38 \\ \\ P=(8x+2x)+(18-38) \\ \\ \boxed{P=10x-20}

So in this context:

Correct option is D. 10x - 20

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weigh
Cloud [144]

Answer:

15 ounces per box

Step-by-step explanation:

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box?

Total weight of crackers in the boxes = 165 ounces

Total number of boxes = 11 boxes

What is the weight, in ounces, of one box?

Weight per box of crackers =

Total weight of crackers in the boxes / Total number of boxes

= 165 ounces / 11 boxes

= 15 ounces per box

The weight, in ounces, of one box is 15 ounces

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?
IgorC [24]

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

  • Length of a tree = 3/4 meters
  • Total time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 years

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.
