Answer the following 3 questions correctly i will know if this is wrong. i will report any incorrect answers! criteria for getting brainliest and not getting reported: - show work - explain if you can't show work why this answer is correct. - and make sure not to post random answers points are taken away when you are reported so don't think about answering it if you want only just want points to move up. 1. solve: 8x + 7 = 55 a) x = 3 b) x = 5 c) x = 6 d) x =7 2. the sum of three consecutive numbers is 72. what are the smallest of these numbers? a) 23 b) 28 c) 32 d) 30 3. solve: (2.3x + 2.8) = (-1.2x + 9.8) a) x = -2 b) x = 2 c) x = 28 d) x = 14

List the sides of δrst in in ascending order (shortest to longest) if: a ∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
