2tv + 3dvd = 1750 4tv + 1dvd = 1250   You can use these two equations to calculate the value of a tv.   Then you can calculate the value of a dvd by substitution

416 is exactly eight  times greater than 52.

H = 25 to 71 inches tall,   H/7 = 0, which means 28, 35, 42, 49, 56, 63,or 70 so H = 7y where y must also be = 2 + 6x   H = 2 + 6x = one of the above. 56 = 2 + 6 times 9,   I think someone can show you a better way but his gives you a hint....

2x + 3y = 21   x - y = 3   x = 3 + y   substitute for x so 2(3+y) + 3y = 21 6 + 2y +3y = 21     you can calculate y and then from that, x

The two key questions are how many marbles in total are there and how many green marbles are there? The answers are 36 and 6.  From those, you can calculate the probability.

The equation for slope is y = Mx + b. M is slope and b is the Y intercept where x = 0, which you are given already

120/3 = 40 miles per hour one hour is 60 minutes 40 miles in 60 minutes From that you can calculate how many miles in 75 minutes: 40/x = 60/75

length = Width + 2  (length + width) times 2 = 32 simplify to length + width  = 16 Substitute (width + 2) for length and you have it. Once you know width, you can calculate length from step one.

I suggest graphing a few points to see what this looks like.  That gives you the answer. The below might help you see the answer.   For x =0, fx = -7   For x = 1, fx = -9 For x = -1, fx =-1   for  x = 2, fx = -7 for x = -2, fx = 9   for...

16 have glasses, brown hair, or both. 7 have glasses which means 9 of the 16 do not have glasses. 14 have brown hair, which means 2 of the 16 do not have brown hair.   The most that could have brown hair and glasses is 7 since only 7 have glasses. If the two who do not have...

We need more information to answer this, more details of the problem, O, etc.  There is not enough context to answer which is why no one has answered.

Plane B goes X mph Plane A goes X + 140 mph   4095/X = Plane B hours   4095/(X+140) = Plane A hours   Plane B hours = Plane A hours + 4   4095/X = 4095/(X+140) + 4   You should be able to calculate the answer...

V = 225   New V each week = V - .75*V So for week 1, New V = .25*V = .25(225) = 56.25 Then for week 2, V = .25 * 56.25 and so on   You could plug this into an Excel spreadsheet formula and cascade down a column and then plot this from the results.  ...

Jen takes x minutes Pat = x - 13 minutes x+X-13 = 42 Solve for X

P **2 - (582+4P) = 90   P**2  - 4P - 672 = 0   Solve for P

A = 23 = L times W W =  2L - 6   23 = L * (2L - 6)   0 = 2L **2 - 6L - 23   Here is a related answer from last year:   The width of a rectangle is 6 less than twice its length. If the area of the rectangle is 102 square centimeters, what...

The total is 90,000 dollars so instead of 9, she would need 9000 donors at 10 dollars each.

I assume that width is not an issue.  It depends upon how much space you want to leave at the top of the box.  If you fill it to the 18 inch top, or 1.5 feet, you have a ratio of 1.5 to 8 feet which converts to a ratio of 1 to 5.33
