9. Petra drives 30 miles on Monday and 40 miles on Wednesday. What is the ratio of Monday's miles to Wednesday's miles in simplest form?

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r

What is [tex] {7}^{98 + \sqrt{4} } - 3 \times (64 \div 2 + 4 - 36) \times a = a + 36[/tex]?

Need ! give step by step solutions on how to solve number one [tex]\frac{9-2\sqrt{3} }{12+\sqrt{3} }[/tex] number two [tex]x+4=\sqrt{13x-20}[/tex] number three (domain and range) [tex]f(x)=2\sqrt[3]{x} +1[/tex]
