Answer:
i think you have to add all the numbers then divide
Step-by-step explanation:
1) -2x = 34
The inverse of multiplication is division, so divide both sides by -2.
x = -17
2) y - 3.5 = -2.1
The inverse of subtraction is addition, so add 3.5 to both sides.
y = 1.4
3) 2/3z = -6
The inverse of division is multiplication, so multiply both sides by 3z
2 = -18z
z = -1/9
Answer:
4/7

Answer:
see explanation
Step-by-step explanation:
(a)
Cost (C) = 4x + (4 × 19), that is
C = 4x + 76 or
4x + 76 = 572 ← equation modelling the situation
(b)
Subtract 76 from both sides
4x = 676 ( divide both sides by 4 )
x = 169
The cost of a ticket is $169
Answer:
(3x-2)(x+4y)
Step-by-step explanation:
3x^2-2x+12xy-8y
3x^2+12xy=3x(x+4y)
-2x-8y=-2(x+4y)
3x^2-2x+12xy-8y=3x(x+4y)-2(x+4y)
(3x-2)(x+4y)
