Ineed with these problems. ! 1. mike's salary is $6,500 per month. he saves 1/5 of his monthly salary and spends the rest. how much money does mike save every month? $ ? how much money does mike spend every month? $ ? 2. fill in the missing values that makes the equation true. −2/5×30= ? /2 x -4 = ? 3. alex takes 1 hour and 30 minutes to get to the office. how many hours does alex spend getting to the office over 4 days? ? hours 4.fill in the missing values that make the equation true. −4/7×49= ? /6 x -14 = ? 5. drag the equivalent expressions into the appropriate columns. 5(1/5+3c) 1/4(1/2 - 4c) (5+15c), (1+15c), (1/8 - c), (1/8 - 4/4c), (-1/8 + -c), (5/5 + 15c) 6. drag the equivalent expressions into the appropriate columns. a(b + c) -x(m - n) (ab - ac), (ab + ac), -(xm - xn), (-xm + -xn) 7. part 1 18 × ? = 1 part 2 select all the statements that explain why the missing value you chose for part a makes the equation true. answer choices a. the product of a rational number and its multiplicative inverse is always 1. b. the sum of a rational number and its additive inverse is always 0. c. the product of two positive rational numbers is always positive. d. the product of any two rational numbers is always 1. e. it is the multiplicative inverse of the multiplier. f. it is the additive inverse of the multiplier. 8. this is an equation. (-)=1 select all of the statements that explain why this equation is true. answer choices a. the fraction -17 is the multiplicative inverse of -71 . b. the fraction -17 is the additive inverse of -71 . c. the product of any two rational numbers is always 1. d. the product of two negative rational numbers is always positive. e. the product of a rational number and its multiplicative inverse is always 1. f. the sum of a rational number and its additive inverse is always zero.
