8x + 7y = 39
4x - 14y = -68
(multiply each term in second equation by -2)
8x + 7y = 39
-8x + 28y = 136
(add both equations)
35y = 175
(divide both sides by 35)
y = 5
(substitute value of y in one of the equations)
8x + 7(5) = 39
8x + 35 = 39
8x = 4
x = 1/2
(x, y) = (1/2, 5)
-45j+-9k
because -9 times 5j is -45j
and -9 times k is -9k
X is 45, z is 45, and y is 90
Answer:
True
Step-by-step explanation:
Even though we cannot see the parallelogram, we can assume the dimensions of the original parallelogram is height= 3 and base= 6.
If we double the dimensions, we get:
height=6 band base=12.
The area of the original parallelogram is 18 square units.
The area of the enlarged parallelogram is 6×12= 72 square units.
Now,
Hence, the area of the larger parallelogram is 4 times more than the original.
Answer:
The average salary of all workers could be any number between $37,596 and $45,500.
Step-by-step explanation:
It is given that according to the Bureau of Labor and Statistics in 2014,
Average salary of all female workers = $37,596
Average salary of all male workers = $45,500
In given problem the options are missing.
Here, the number of male and female are not given, so we can not find an exact average salary of all workers. But the average salary of all workers must be lies between the average salary of male and female.
Therefore. the average salary of all workers could be any number between $37,596 and $45,500.
