Answer:

<u>A</u> [914 ÷ 7 – 233 ÷ 7] and <u>B</u> [(914 – 233) ÷ 7]

Explanation:

Order of Operations: P.E.M.D.A.S.

Parentheses (when working with operations in parentheses, follow the order below)

Exponents (expressions in exponents: follow order of operations)

Multiplication

Division

Addition

Subtraction

distinct operation: subtract 233 from 914

distinct operation: divide difference by 7

A is <em><u>correct</u></em> because it <u>contains the actual division in parentheses</u>. You would <u>divide</u> each number by 7 (thus, <em>7 times smaller</em>) and then <u>subtract</u> the quotients. We simply <em>divided first</em>, thus <em>rewriting</em> (914 – 233) in a <em>different</em> <em>form</em>. We still get the same answer thanks to P.E.M.D.A.S.  It is the same as <u>distributing the division by 7</u> to <u>each term</u> using the Distributive Property.

B is <em><u>correct</u></em> because it <u>includes the subtraction in parentheses</u>. Therefore, you <em>subtract 233 from 914</em> before <em>dividing the difference by 7</em>, exactly as the question asked. It is the <em>same</em> as <u>factoring the division by 7</u> out of the subtraction as if it were a polynomial.

C is <u><em>incorrect</em></u> because it puts the division by 7 in between 914 and 233, meaning <em>it divides 914 by 7</em> before <em>subtracting 233 from the quotient</em>

D is <u><em>incorrect</em></u> because there are <u>no parentheses around the subtraction</u>. According to P.E.M.D.A.S., we divide before we subtract. Because there are <u>no parentheses</u>, we <em>divide 233 by 7</em> before <em>subtracting the quotient from 914</em>.

Hope this helps! Have a great day!

lesya [120]

Answer:

The correct answer is C

Explanation:

This painting is by Mary Cassat. She chose to use oil paints. When Cassat chose to use oil paints, she most likely considered that oil paints are slow drying which can make them difficult to work with, but also allow mixing and blending of colors to create various affects. She would have also considered that oil paints are long-lasting and retain their vibrancy over time.
