Answer:
Total weight = 1,500 tons
Step-by-step explanation:
Given:
l = 5 ft
b = 5 ft
h = 6 ft
One cubic foot weighed = 0.1 tons
Find:
Total weight
Computation:
Volume = lbh
Volume = (5)(5)(6)
Volume = 150 ft³
Total weight = Volume / 0.1
Total weight = 150 / 0.1
Total weight = 1,500 tons
X^2 + y^2 = 8
X-y=0 so x = y
replace x = y into X^2 + y^2 = 8
y^2 + y^2 = 8
2y^2 = 8
y^2 = 8/2
y^2 = 4
y = - 2 and y = 2
because x = y
so x = - 2 and x = 2
solutions:
x= - 2 and x = + 2
y= - 2 and y = + 2
Answer:
17y+4z-5
Step-by-step explanation:
The answer is 1.53x10^10 dollars.
You get this answer by multiplying the total amount of goods in tons (900,000) by the average value of the goods ($17,000 per ton) to get your answer of 1.53x10^10 dollars.
17k - 6k- 5k - 2k - k = 15
17k - 6k is 11k.
so, 11k - 5k - 2k - k =15
11k-5k is 6k
so 6k - 2k - k
6k - 2k is 4k
so 4k - k
4k - k is 3k
so 3k = 15
Take 3 to the other side -- k= 15/3
final answer is k = 5
