We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
<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>
Assuming this is written correctly, with no x in the equation, we just solve for y:
y = -3 - 1/3 = -10/3 = 0 x - 10/3
That's slope-intercept form.
Answer: Slope 0, y-intercept -10/3
