Question 4.
The multiples of 7 are those numbers obtained from the product of 7 and a whole number.
The multiples of 7 between 50 and 70 are:
You could be 56 or 63
For one cup of sugar, you would use 1 4/5 cups of flour
(8r+3s)(8r-3s) dont have working but noticed that it is the difference of two squares
So here's PEMDAS:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
So we will complete this equation in that order. So first is solving the problem within the <u>parenthesis:</u>
<em>(12)</em> ÷ 4 · 7 - 4² ÷ 4 =?
Then we solve all the parts including an <u>exponent:</u>
12 ÷ 4 · 7 - <em>16</em> ÷ 4 = ?
Next, we solve the parts with<u> multiplication: </u>
12 ÷ <em>28</em> - 16 ÷ 4 = ?
Then, we solve for all the <u>division:</u>
<em>0.43</em> - <em>4</em> = ?
If there was any addition we would do that next, but because there is none, we move onto<u> subtraction:</u>
0.43 - 4 = -3.57
So, your <u>answer</u> is -3.57
