Answer:
The cubic foot of wood = 1,728 cubic inches.
So a cubic inch weighs (72 / 1,728) pounds = 0.041666666... pounds
3" x 4" x 5" = 60 cubic inches
60 cubic inches * .04166666... pounds / cubic inch =
2.5 pounds
Step-by-step explanation:
Answer:
The solution set is (2,4).
Step-by-step explanation:
Given that:
−2x + 2y =4 Eqn 1
−4x + 8y =24 Eqn 2
Multiplying Eqn 1 by -2
-2(-2x+2y=4)
4x-4y= -8 Eqn 3
Adding Eqn 2 and 3
(-4x+8y)+(4x-4y)=24-8
-4x+8y+4x-4y=16
4y=16
Dividing both sides by 4
Putting y=4 in Eqn 1
-2x+2(4)=4
-2x+8=4
-2x=4-8
-2x=-4
Dividing both sides by -2
Hence,
The solution set is (2,4).
112.50 divided by 15 is 7.5= 7.50 so 7.50 times 10 is $75.00 so answer is $75.00
