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.

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)

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?'
