Answer:
(x= -7 , y = -1) is the complete solution of the equation.
Step-by-step explanation:
The given equation is -7x - 5y = 54
Now, here substitute x = -7
So, we get
-7(-7) -5y = 54
or, 49 - 5y = 54
⇒ -5y = 54 - 49
or, -5y = 5
⇒ y = 5/(-5) = -1 , ⇒ y = -1
Hence, (x= -7 , y = -1) is the complete solution of the equation.
We need to find the volume of a rectangular prism with dimensions 6 ft, 10 ft, and 12 ft:
• The volume of a rectangular prism is given by the product of its dimensions.
Thus, the volume V of the room is given by:
Therefore, that volume is 720 cubic feet.
For area, just multiply the length x width
So therefore, multiply 36 inches x 48 inches and there you have it.
Now for the perimeter, it is a little different
You'd have to add the sides up together to get your answer for the perimeter.
So, 36 in + 36 in + 48 in + 48 in = answer
Answer:
x = 3
y= 1
Step-by-step explanation:
for x:
sin (60°) = x/2
x = (sin 60) × 2
x = √3
for y:
cos (60°) = y/2
y= 2 × (cos 60)
y= 1
