Answer:

True when x = -3/5; false otherwise

Step-by-step explanation:

Note that -4(5x) = 12 => -20x = 12, so that x = -3/5. The given equation is solveable, and the solution is -3/5. Asking whether -4(5x)=12 is "true" or "false" is pointless; this equation is conditionally true, with that truth hinging on x = -3/5. Similarly, -4(5x)=12 is not describable by "open."

juin [17]

Answer:

The farmer bought 36 pigs in all.

Step-by-step explanation:

Given that a farmer bought a number of pigs for $ 160, but, however, 8 of them died before he could sell the rest at a profit of 6 per pig, and his total profit was $ 8, to determine how many pigs did he originally buy the following calculation must be performed:

160 + 8 = 168

168/6 = 28

28 + 8 = 36

Thus, the farmer bought 36 pigs in all.

Y(a -b) =c(y+ a); y

Ksivusya [100]

Answer:

y = ac / (a - b - c)

Step-by-step explanation:

y(a - b) = c(y + a)

Distribute

ay - by = cy + ac

Subtract cy from both sides

ay - by - cy = ac

Factor out y

y(a - b - c) = ac

Divide both sides by (a - b - c)

y = ac / (a - b - c)
