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:
Step-by-step explanation:
hello :
2x²+12x+2y²−16y−150=0
divide by 2 : (x²+6x)+(y²-8y)-75 =0
(x²+6x+9)-9+(y²-8y+16)-16-75 =0
(x+3)²+(y-4)² =10²
The coordinates of the center are (−3,4), and the length of the radius is 10 units.
Answer:
<em>The answer is 6</em>
Step-by-step explanation:
<em>2 + 2 + 2 = 6</em>
<em></em>
3x+1.5y≤25 X represents board games and each board game weighs 3 lbs (3x). Y represents remote controlled cars which each weigh 1.5 lbs (1.5y). The inequality sign (less than or equal to, ≤) is used because in total the amount of board games and remote controlled cars CANNOT exceed 25 lbs.
A proportional relationship is used to illustrate linear equations.
The constant of proportionality is 3
From the table, we have the following points:
(x,y) = (2,6) (3,9)
The constant of proportionality is calculated using:
So, we have:
Subtract
Divide
Hence, the constant of proportionality is 3
