Hi!
We will solve this using ratios, like this:
1 shelf holds 45 pounds
x shelves hold 270 pounds
______________________
x = (270*1)/45
x = 270/45
x = 6
6 shelves will be needed to hold 270 pounds of boxes.
Hope this helps!

Step-by-step explanation:
A theatre has 4 chair in a row; lets draw that out
Let's pretend that this is a chair: ♦
So we have 4 chairs in a row

Let's find the perimeter;
4 + 5 + 4 + 5
=18
The perimeter is 18 rows.

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:
a + b = 155000 (1)
Also:
0.1a + 0.08b = 14100 (2)
From both equations:
a = 85000, b = 70000
Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
