Five quarts of latex enamel paint will cover about 100 square feet of wall surface. how many quart are needed to cover 71 square feet of kitchen wall and 69 square feet of bathroom wall ?

71 + 69 = 140so there is 140 sq ft to cover

100 / 5 = 140 / x100 sq ft to 5 qts = 140 sq ft to x qts
cross multiply
(100)(x) = (140)(5)
100x = 700
x = 700/100
x = 7 qts < 7 qts will be needed

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
