I don’t understand what your asking. there is no numbers involved or a equation.
1.) Convert 30 kg into pounds
30 kg = 66 lb
2.) A five-year-old boy weighed 66 pounds at his appointment.

0
Step-by-step explanation:
Answer:
r= -15
Step-by-step explanation:
when a negative subtracts a negative you just add more negatives
2r
r= -15
2x-15= -30, -30- -6= -36
Answer:
(-1, 7, 2)
Step-by-step explanation:
we suppose that ax + by + cz = d for the matrix
D = det [ 0 4 7] = 100
-6 0 -2
1 2 8
Dx= det [ 14 4 7] = - 100
10 0 -2
-3 2 8
Dy= det [ 0 14 7] = 700
-6 10 -2
1 -3 8
Dz = det [ 0 4 14] = 200
-6 0 10
1 2 -3
So the solution is:
x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2
(-1, 7, 2)
have a good day!
