Step-by-step explanation:
<u><em>The complete question is</em></u>
Angelo recently opened a bank account and deposits the same amount each week. After 8 weeks, he deposited $280. He wants to deposit a total of 420 in his account. How many weeks will it Angelo to deposit a total of $420
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Let
x ----> the number of weeks
y ----> the total deposit in the bank account
In this problem we have a proportional relationship between the variables x, and y.
we have the ordered pair (8,280)
Find the constant of proportionality k or slope of the linear equation

so
The linear equation is

For y=420
Substitute in the linear equation

Solve for x

1200 squares because, 3 m = 300 cm and a square has 4 sides so you times 3 and 4 and you get 12 so 12 m = 1200 cm
16 feet because it’s 3/7 of it
