16. Don't ask for a formula on how to do this. I just played around with the numbers and figured that it would take 9 quarts of the $1.40 oil to 14 quarts of the 90¢ oil. Take it from there.

The length of a rectangle is 3 better than two times its width. the fringe is 40 8 ft. discover the width. L = 2x+3 W=x 40 8 = 2(2x+3) + 2x 40 8 = 4x+6 + 2x 40 8 = 6x+6 40 two = 6x x = 8 So length is: 2x+3 2(8)+3 length: 19 15 better than 4 situations a huge decision is 6 better than 5 situations the huge form. discover the huge form. 4n+15 = 5n+6 9 = n huge form is 9 Martha and Sally had lunch collectively on Tuesday. Sally paid $2 better than Martha. If the whole bill became $5.sixty 4, how plenty did Sally pay for her lunch? Sally: 2+x Martha: x 5.sixty 4 = 2+x+x 5.sixty 4 = 2x+2 3.sixty 4 = 2x a million.80 two = x Martha paid a million.80 two and sally paid 3.80 two Bob paid 3 decrease than Tim for his lunch at a community pizza parlor. collectively they spent $7.80. How plenty did Bob spend for his lunch? Use comparable technique as above there have been 6 extra women persons on a committee than men. If the committee became made out of 30 people, what number men have been on the committee? women persons: x+6 men: x 30 = x+6+x 24=2x x=12 So 12 men and 18 women persons 3 consecutive integers have the sum of 153. what's the 2nd integer? x - first integer x+a million 2nd integer x+2 0.33 integer x+x+a million+x+2 = 153 3x+3 = 153 3x=a hundred and fifty x=50 First integer is 50, 2nd integer is fifty one, and 0.33 integer is fifty two The sum of three consecutive even integers is fifty 4. what's the 1st consecutive integer? x = first integer x+2 = 2nd integer (even) x+4 = 0.33 integer (even huge form) x+x+2+x+4 = fifty 4 3x+6 = fifty 4 3x = 40 8 x = sixteen First integer is sixteen An aircraft flies at a value of 356 km/h. If the aircraft travels a entire distance of 1424 km, how long became it interior the air? speed = distance/time 356 = 1424/time time = 1424/356 time = 4 hrs

This is the fourth desperate algebra question you have asked tonight. Try doing your own homework, instead of spending so much time trying to get someone else to do it for you.

You have a better shot at getting help if you just list one problem at a time. People don't want to help kids who don't even try.
