Rick bought 5 pounds of steak.
Step-by-step explanation:
Given,
Cost per pound of steak = 13.50
Cost per pound of chicken = 3.25
Total bought = 8 pounds
Total paid = 77.25
Let,
x represents the pounds of steak purchased
y represents the pounds of chicken purchased
According to given statement;
x+y=8 Eqn 1
13.50x+3.25y=77.25 Eqn 2
Multiplying Eqn 1 by 3.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 10.25
Rick bought 5 pounds of steak.

Answer:
k = -20.
Step-by-step explanation:
Do the division:
4x ) 12x^2 + kx ( 3x
12x^2 + k/4
So k/4 = - 5
k = -20.
Answer:
x = -3 or x = -5/3
Step-by-step explanation:
Solve for x over the real numbers:
(x + 3) (3 x + 5) = 0
Split into two equations:
x + 3 = 0 or 3 x + 5 = 0
Subtract 3 from both sides:
x = -3 or 3 x + 5 = 0
Subtract 5 from both sides:
x = -3 or 3 x = -5
Divide both sides by 3:
Answer: x = -3 or x = -5/3
