Solve 2x+3y=18 equation
Nina [5.8K]
Here's the graph of your equation, instructions on how to plot is in the image. if there's a second line equation, you could use the method shown to plot that too, and the x and y values of the intersection point would be your answer. 

you could also use algebra to simultaneously solve the two equations to obtain x and y as well, feel free to ask!

hope that helps :) sorry it's not a definite answer

valentinak56 [21]

The average number of fish per cubic kilometer is 1. 8 \times 10^4.

The correct option is B.

Given

The volume of one of the Great Lakes is 3.5 × 103 cubic kilometers.

The number of fish in the lake = 6. 3 × 107.

<h3>What is the average value?</h3>

The average is the middle value of the given data set and is calculated by adding up all the numbers and dividing the result by the total quantity of figures added.

The average number of fish per cubic kilometer is given by;

\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}

Substitute all the values in the formula;

\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}\\\\ \text{The average number of fish per cubic kilometer}= \dfrac{6.3\times 10^7}{3.5\times 10^3}\\ \text{The average number of fish per cubic kilometer}= 1.8 \times 10^4

Hence, the average number of fish per cubic kilometer is 1. 8 \times 10^4.
