School bus : 9 tons = 9*2000 = 18,000 pounds
Horse : 1,100 pounds
Elephant : 5,500 kilograms = 5,500*2.2 = 12,100 pounds
Grand piano : 15,840 ounces = 15,840/16 = 990 pounds
So the answer is
Answer:
x = 4.5
y = -5
Step-by-step explanation:
2x - 3y = 24 2x + y = 4
y = -2x + 4
2x - 3(-2x + 4) = 24 y = -2(4.5) + 4
2x - (-6x + 12) = 24 y = -9 + 4
2x + 6x - 12 = 24 y = -5
8x - 12 = 24
8x = 36
x = 4.5

Answer:
The Principal = $75,000
Step-by-step explanation:
Formula for finding the principal:
I × 100/ R × T
Therefore;
Principal = 45 × 100 / 3/ 100 × 2

Which means that the Principal is $75,000.00
Answer:
x=10
Step-by-step explanation:
1/2x+4=9
subtract 4 from both sides
1/2x=5
multiply both sides by 2 to get x by itself
x=10
