<p>for one of the grid in did you guys get 1.75? :o</p>

<p>the question was like if 3/4x = 3/4 what is 3/4 + x?</p>

<p>@yankee i thought so to it was like the #2 question in one of the sections xD</p>

262

<p>what did you guys get for the parallelogram question?</p>

263

<p>Yes to both I and the 1.75 and the .8</p>

264

<p>@arc I put 1.75 for that as well.</p>

265

<p>Do you guys also remember a question where it was two parallel lines, there was a 2y and 3y and it asked what x was?</p>

<p>I got 72, cause 5y equals 36 and I believe 2y was the same as X, but i always get confused on the inner adjacent angles when I do parallel line questions ><</p>

266

<p>yea i remember now, it was a cake question, misread the problem</p>

267

<p>@arc - you got it right.</p>

268

<p>The question about the box being filled with water…did it ask to find new height when the side with the GREATEST area was laid flat or the side with LEAST area?</p>

269

<p>What were the numbers again? Aren’t the angles opposite each other the same in a parallelogram.</p>

270

<p>x = 108</p>

<p>remember 3y + 2y = 180
y = 36</p>

<p>3y = x
3(36) = 108</p>

271

<p>@tornado it was least area which would have been the 2x3 faces</p>

272

<p>@tornado - It said the side with the least area.</p>

273

<p>wow i read wrong and got 4/3 as an answer</p>

274

<p>@Arctk3 - 5y was not 36</p>

<p>the angle with 2y made a straight angle with 3y, so 3y + 2y = 180 and then u solve</p>

275

<p>Sorry meant that 5y equaled 180, and that each y was 36 degrees xD, and are you sure the answer was 108 and not 72?</p>

<p>I thought it was 72 because if you look at 2y across from it is the angle equal to it and that angle is an interior adjacent angle to the angle that is across from x and wouldn’t that make x 72 then?</p>

276

<p>@herny It was 2y=x. 72</p>

277

<p>@ arc - yea ur right, that was a mistake mmmm :confused: i missed that</p>

278

<p>i’m not sure if this has already been asked but z + x+ y=500, and z-x- y= equal 200, x+ y was it 150 or something else? xD</p>

279

<p>@Arc
it was 150</p>

280

<p>@Arctk3</p>

<p>x+y+z=500
x-y-z=200</p>

<p>2x=700
x=350</p>

<p>y+z=500-350
y+z=150</p>
