Answer:
The 2 numbers are 512.8 and 487.2.
Step-by-step explanation:
Let the numbers be x and y, then:
x + y = 1000............(1)
x^2 - y^2 = 25600
(x + y)(x - y) = 25600
1000(x - y) = 25600
x - y = 25.6............(2)
Adding (1) + (2):
2x = 1025.6
x = 512.8
so y = 1000 - 512.8
y = 487.2.
The answer is 56! I used a double number line! You have to get the unit rate first! Unit means 1, you have to get from 12 to 1! I did 12 divided by 12, and got 1! Whatever I do to the bottom I do to the top. So I divided 60 by 12 and got 5. Now we have to get to seven, so I multiplied 1 x 7 and got 7. Than I multiplied 5 times 7 and got 56! I hope <em>I helped! :D</em>
Answer:
Let the midpoint be M(x,y).
7) x= (3+1)/2= 4/2= 2
y= (-9+5)/2= -4/2= -2
M(2,-2)
8) x= (5-6)/2= -1/2= -0.5
y= (-1-3)/2= -4/2= -2
M(-0.5,-2)
