using the formula to proof:
True. proved that they are identical.
Money spent + money left over = total money
money spent + 9 = 30
We don't know the price of each shirt, so let x = price of 1 shirt.
Then, 3 shirts cost 3 times as much as x, or 3x.
She spent 3x.
3x + 9 = 30

Answer:</h2>
<u>The correct option is 3x + 4y = 10</u>
<h2>
Step-by-step explanation:</h2>
The standard form for any linear equations having two variables is written as Ax+By=C. For example, 3x+4y=10 is a linear equation in standard form. When an equation is given in this form, it becomes easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations whose solution is required to find the point of intersection of given lines.
Answer:
The terms are 9, 4, 3b and 7a.
