Answer:
3/k = x
Step-by-step explanation:
5kx +6 = 7kx
Subtract 5kx from each side
5kx -5kx +6 = 7kx-5kx
6 =2kx
Divide each side by 2k
6 /2k = 2kx/2k
3/k = x
Answer:
150 workers are at the company
Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
so 100% of the workers is equal to 150 workers
Answer:
True
Step-by-step explanation:
Every orthogonal matrix is invertible. This is a true statement.
Orthogonal matrices are square matrix whose rows and columns are orthogonal unit vectors.
In an orthogonal matrix columns are linearly independent and since the columns are linearly independent the matrix will be matrix will be invertible. This is according to invertible matrix theorem.
Answer: 
pounds
Step-by-step explanation:
Let x pounds of $ 0.66 per lb candies mixed with y pounds of $ 1.31 per lb candies to obtain 9 lb of $ 0.97 per lb candies,
Hence, we can write,
x + y = 9 ------- (1)
And, 0.66 of x + 1.31 of y = 0.97 of (x + y)
⇒ 66 x + 131 y = 97 (x+y)
⇒ 66 x +131 y - 97 x - 97 y = 0
⇒ -31 x + 34 y = 0 ------(2)
By solving equation (1) and (2)
We get,
and 
Hence, the quantity of 0.66 per lb candies = pounds
