Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Answer:
5
Step-by-step explanation:
i don't see the graph
but i would think this would be the answer.
The first graph with the month in numbers because the X value which is the month never appears again while the other appears again or attached to-other y value
Given that total amount of metal in the beginning = 8.2 square feet
Given that used amount of metal = 2.1 square feet
Then remaining amount of metal = (8.2-2.1) = 6.1 square feet
Now it says that "$183 worth of sheet metal remaining".
That means cost of 6.1 square feet is $183.
Let cost of 1 square feet of the metal = x
Then cost of 6.1 square feet of the metal = 6.1x
Both expressions 6.1x and $183 represent the cost of the remaining metal so the required equation will be:
6.1x=183
Now we can solve it to find the solution
x=183/6.1
x=30
So the cost per square feet of the metal = $30
Hence final answer is $30 per square feet.
Answer:
Step-by-step explanation:
When two fair dice are tossed sample space consists of 36 events
(1,1)....(6,6)
A_ The difference of numbers is 2 or less
Favorable outcomes = 
Hence Probability = 
B) A 4 does not appear on either die
Then we must not have these

Hence probability = 
C: The sum of numbers is 10 or more:
FAvourable outcomes are:

Probability =
