Answer:
(x, y) = (-3, 2)
Step-by-step explanation:
Put the given value of y into the equation and solve for x.
... 7·2 +3x = 5
... 3x = -9 . . . . . . subtract 14
... x = -3 . . . . . . . divide by the x-coefficient
The solution (x, y) is (-3, 2).
Answer:
X ≥ 10
Step-by-step explanation:
Answer:
a ≈ 8.9
Step-by-step explanation:
Set up the equation as so:
8a^2 + 2 = 634
First, subtract two from both sides:
8a^2 = 632
Then, divide by 8 to further isolate the variable.
a^2 = 79
To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
Answer:
The answer is 53,333 rounded
Step-by-step explanation:
So you multiply 74,000 by 2/3 you get 49,333
Then you take that number and add 4,000 and you get 53,333 rounded.
Answer:
12
Step-by-step explanation:
the angles of a triangle all add up to 180
thus, we can combine every term given and set them equal to 180 and solve for x
