Answer:
18 tons
Step-by-step explanation:
a) Given: Weight of 1 truck=4500 pounds
Thus, weight of 8 trucks= pounds
We know that 1 ton=2000 pounds
Thus, weight of 8 trucks in tons=
Hence, the total weight in tons the cars on the truck= 18 tons.
b) Given: Dimensions of the room are as
Length=10 yards and width= 168 inches
We know that 1 yard=3 feet and 1 inch=
Thus, length
width=
The difference between length and width=
Hence, the length of the room exceed the width by 16 feet.
45/56
5/7 divided 8/9
5/7 times 9/8
45/56
Answer:
2x+6y = 10
3x+9y = 15
Step-by-step explanation:
We can multiply the equation by 2
2( x + 3y )= 5*2
2x+6y = 10
Or we can multiply by 3
3( x + 3y) = 5*3
3x+9y = 15
Multiplying each side by the same number gives us an equivalent equation
Standard form is
Ax +By = C
Which the equation is already written in
