Answer:
y = -0.5
Step-by-step explanation:
given
5x – 7y = 7 ------- eq 1
y = -5x + 3 (we rearrange this so that the terms are in the same order as eq 1)
-5x – y = -3 ----- eq 2
by elimination, eq 1 + eq 2
(5x – 7y) + (-5x – y) = 7 + (-3)
5x - 7y -5x - y = 7-3
-8y = 4
y = 4/(-8)
y = -0.5
Answer:
At least 0.9, so I think b.
Step-by-step explanation:
Its 2.59%. i mean i figured it out and i got 2.59%
The LCD = 6x^2y^3 ( because LCD of 3 and 6 = 6, LCD of x^2 and x = x^2 and LCD of y and y^3 = y^3)
now divide 3x^2y into the LCD then multiply this by 5 to get the first term in the numerator and do similar process to get second term, so we get:-
5(2y^2) - 4(x)
------------------
6x^2y^3
= 2( 5y^2 - 2x)
-----------------
6x^2y^3
= 5y^2 - 2x
-----------
3x^2y^3
Answer:
