<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
You can use the distributive property of multiplication over addition to find the equivalent expression to the given expression.
The expression which is equivalent to the given expression is given by
Option D:
Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
<h3>What is distributive property of multiplication over addition?</h3>Suppose a, b and c are three numbers. Then we have:
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
<h3>Using the above property and the fact that 28 and 35 are multiples of 7 to get the equivalent expression</h3>The given expression is
Since 28 = 7 times 4 and 35 = 7 times 5
Thus,
Thus,
The expression which is equivalent to the given expression is given by
