0.4x + 3.9 = 5.78
1. Subtraction property of equality:
Subtract 3.9 from both sides of the equal sign:
0.4x = 1.88
2. division property of equality:
Divide both sides of the equal sign by 0.4:
X = 4.7
Answer:
4 times it is tails
Step-by-step explanation:
Sample Space: 1H, 1T, 2H, 2T, 3H, 3T, 4H, 4T
H= heads
T= tails
Event is is tails; 1T, 2T, 3T, 4T
4 times or 50% chance

To figure this out, you need to divide 28/8 to get the cost per hinge from Marks hardware
To figure out Steves Supplies cost per hinge you need to divide 38/11
Mark's = 28 / 8 = $3.50
Steve's = 38/11 = 3.45
Steve has the best deal because it cost $3.45 per hinge. The answer is C
Answer:
