Ok, since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25!!!!! :)
-8x=16. X=-16/8. X=-2. The answer is the second choice. X=-2.
Answer:
125/100 x N = 370
x 100 x 100
125n = 37,000 (since your multiplying what you got to the variable)
Divide by 125
N = 296
Length=2w+59
the perimeter would be:
2w+2(2w+59)
2w+4w+118
P=6w+118
Answer:
x = 5, y = -2.
Step-by-step explanation:
3x+2y=11
2x-2y=14
Adding removes the y terms:
5x = 25
x = 5.
Substitute for x in the first equation:
3(5) + 2y = 11
2y = 11 - 15 = -4
y = -2.
