50 students on the fist day and you multiply that by .20 to find how much is 20 percent of 50. You take that number which is 10 and subtract it from 50 so 50-10=40 which is how many showed up the second day
Just Math
50*0.2=10
50-10=40 students
Answer:
(-2, 9)
Step-by-step explanation:
1) Multiply each term of the top equation by two.
2(x) + 2(y) = 2(7)
2x + 2y = 14
2) Use elimination to get rid of the y's
2x + 2y = 14
-(5x + 2y = 8)
Translates to...
2x + 2y = 14
+ (-5x - 2y = -8)
= -3x = 6
3) Solve for x by dividing each side of the equation by -3.
x = -2
4) Plug in x to find the y-value
x + y = 7
-2 + y = 7
-2 + 2 + y = 7 + 2
y = 9
I hope this helps!
Also draw the figure and from the above solu. it is prooved that ABCD is a kite
Answer:
Step-by-step explanation:
