So we know that the decimal place will move one right. Well basically let's assume she could have bought these expressions:
x 10 x 3.50 = 35.00
x 9 x 3.50 = 31.50 + 3.75 = 35.25
x 8 x 3.5 = 28 + 3.75 x 2 = 35.5
x 7 x 3.5 = 24.5 + 3.75 x 35.75
We know that there is a pattern. See how the cents goes .25 up each time. So we know she'd buy 6 reams of white because (6 x 3.5 = 21) + (4 x 3.75 = 15) = 36.
Answer:
<h3>x = <u>8</u></h3><h3> 3</h3>
Step-by-step explanation:
<h3><u>3</u> + 2 = 4</h3><h3>4</h3><h3>Subtract 2 from both sides of the equation. </h3><h3><u>3</u> x + 2 _ 2 = 4 _ 2</h3><h3>4</h3><h3>Simplify</h3>
<u>3</u> x = 2
4
<h3>Multiply all terms by the same value to eliminate fraction denominators. </h3>
<h3>3/4x = 2</h3>
<h3>4 × <u>3</u> = 4 × 2</h3><h3> 4 </h3><h3>Divide both sides of the equation by the same term. </h3>
<h3>3x = 8</h3>
<h3><u>3</u> x = <u>8</u></h3><h3>3 3</h3>
<h3>x = <u>8</u></h3><h3><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>3</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u></h3>
But I would say the answer could be the number of fish caught is a function of time spent fishing.
