Answer:A, B and D

Step-by-step explanation:

A linear relationship is one in which when the variables are plotted, the graph would be a straight line. In a linear relationship, the highest power of the variables is 1. We would compare each of the given relations.

A) Double x and subtract five to get y. This is expressed as

2x - 5. It is a linear relationship.

B) Multiply x and y to get 20. This is expressed as

xy = 20. It is a linear relationship.

C) Multiply x times itself and add five to get y. This is expressed as

x^2 = y. It is not a linear relationship. The highest power of the variables is 2

D)Divide 40 by x to get y. This is expressed as

40/x = y. It is a linear relationship.

If $20.00 is for 12.25kg of peas ...what weight of peas can i get for $4.00

Alina [70]

2.45kg

First you calculate the price per kg as follows:

If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg

If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.
