Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb weights and y represents the number of 10 lb weights, which equation can be used to find the number of each type of weight Bob has?
Answers
Answer 1
Answer:
The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.

10. if we were tosubsitute the points and graph the equation we would notice that theshape is the same for both: a 45 degree angle line that goes upleft andup right the graph of y=|x| looks like a right angle corner that is facing up that is ballancing on the point (0,0) thegraph of y=|x|-4 is the same except that the graph is shifter 4 unitsto the right ie. the point ofo the graph/rightangle is on point (4,0)
14. slope intercept form which is y=mx+b m=slope b=y intercept m=4/3 y=4/3x+b one given solution/point is (9,-1) one solution is x=9 and y=-1 so subsitute and solve fo b -1=4/3(9)+b -1=36/3+b -1=12+b subtract 12 from both sides -11=b the equation si y=4/3x-11 see which one converts to the correct form after trial and error we find that y-1=4/3(x-9) is the answer
270 is 75% of what number?
Answers
First, you have to divide 270 by 3, so you get 25%. This comes out to be 90. So, 90 is 25%. Now, multiply this by four to get 100%. This comes out to be 360. So, 270 is 75% of 360, which answers the question '270 is 75% of what number?'
