Answer:
Step-by-step explanation:
The factors common to 20 and 10 are 1, 5 and 10. The largest of these is 10. That's the GCF of 20 and 10.
Answer:
1) x = 18, y = -5
2) x= 1, -3 y = 3, -1
Step-by-step explanation:
1)
x+y=13
y = 13-x
2x-y=5
2x-(13-x) = 5
2x - 13 + x = 5
x - 13 = 5
x = 18
x + y = 13
18 + y = 13
y = -5
2)
y = x+2
x^2 + y^2 = 10
x^2 + (x+2)^2 = 10
x^2 + (x+2)(x+2) = 10
x^2 + x^2 + 4x + 4 = 10
2x^2 + 4x + 4 = 10
2x^2 + 4x - 6 = 0
2(x^2 + 2x - 3) = 0
2(x-1)(x+3) = 0
x = 1, x = -3
y = x+2
y = 1 +2 = 3
y = -3+2 = -1
The value of x would be 6.7, just do 6.3+5.6+8.4=20.3 27-20.3=6.7! Hope it helps
