Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two. Hisheating budget for the winter is $600. (7.1)a. Write a linear equation that describes the problem.

The linear equation can be written as

Step-by-step explanation:

Given that "Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two"

And his heating budget for the winter is $600

To find a linear equation that describes the problem:

Let the cords of wood be x and let sing natural gas be y

So that the combination of the cords of wood and sing natural gas is x+y

Now the linear equation can be written as

215.92 dollars is the answer

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
