Answer:
x = -5
Explanation:
4(2x + 10) = 0
[ Simplify both sides of the equation ]
4(2x + 10) = 0
(4)(2x) + (4)(10) = 0 [Distribute]
8x + 40 = 0
[ Subtract 40 from both sides ]
8x + 40 − 40 = 0 − 40
8x = −40
[ Divide both sides by 8 ]
8x / 8 = −40 / 8
x = -5
Answer:
125$
Step-by-step explanation:
if it's proportional that means it will move up or down in equal amounts
going down from 20 to 5 kg means I divided by 4
so I can also divide 500 by 4 and get 125$
Answer:
Step-by-step explanation:
x + y + z = 1
-x + 9y - 3z = -49
10y - 2z = -48
2x + 4y + 2z = -6
-2x + 18y - 6z= -98
22y - 4z = -104
-20y + 4z = 96
2y = -8
y = -4
10(-4) - 2z = -48
-40 - 2z = -48
-2z = -8
z = 4
x - 4 + 4 = 1
x = 1
x = 1, y = -4, z = 4
