Objective 3: Solve work problems Q25 Solve a work problem Homework. Unanswered Jennifer can sew 120 masks in 20 hr and Janice can sew 120 masks in 30 hr. How many hours does it take them to sew 120 masks if they work together?
Step-by-step explanation:
i think u should've put it in that format
The answer is A 9.4 because you use the Pythagorean theorem to find the unknown side.
<span>The difference of X and the number is six what is the other number.
Write "the difference between X and another number (Y) is 6." Find Y.
X-Y=6, or Y = X - 6 This is the equation of a straight line. Can't solve this problem for Y without knowing more about X. Ensure that you have copied down ALL of the original problem.</span>
