Answer:
20 inches
Step-by-step explanation:
7 × x - 7 × 20
You could rewrite it this way, 7 x (x-20), but the answer above is better 'cause it takes away the grouping symbols
<h2>Greetings!</h2><h3>To find the total area of the bowling ball, which we presume is spherical, the equation is:</h3>
πr³
<h3>So we know that the radius is 5, so we can substitute that into the equation:</h3>
x π x 5³ = 523.599 or 524 to 1dp.
<h3>Seeing as this is 524 cubic inches, we can convert this into pounds by dividing this by 100, because one cubic inch weights
as stated.</h3>
524 ÷ 100 = 5.24lb
<h3>So your answer would be B, 5.24lb.</h3>
<h2>Hope this helps!</h2>

The probability of her getting a red marble is the number of red marbles divided by the number of total marbles. Since she picked a green marble first, we must subtract one marble from the total number of marbles, so that the total # of marbles is 6 + 6 + 4 = 16 - 1 (green marble) = 15. Since there are 6 red marbles, our probability is 6/15 or 2/5. Converted to percentage form, this is 0.4 —> 40%
To solve an equation for one variable, we will utilize PEMDAS ( parentheses, exponents, multiplication/division, add/subtract) but backwards. So we will first add/subtract any numbers to the other side to get the variable by itself. We will then divide/multiply any numbers to get the variable by itself.
