Answer:
Negative 3,2
Step-by-step explanation:
6x+2y=6...(1)
7x+3y=5...(2)
Multiply (1) by 3
18x+6y=18...(3)
Multiply (2) by 2
14x+6y=10..(4)
Substrate (4) from (3)
4x=8 divide both sides by 4
X=2
Substitute x=2 in equation (1)
6(2)+2y=6
12+2y=6
Substrate 12 from both sides
2y=-6
Divide both sides by 2
y=-3
Therefore x=2 and y=-3
Negative 3 and 2
Answer:
let the unknown rational number be X.
26/X=39
X=39/26
X=3/2
Recall that cos = adj / hyp, yields cosx = 21 / 29.

Step-by-step explanation:
you can always equal two similar triangles so that they become congruent.
In the ratio of the length of their sides is equal to one, they are congruent. So, all congruent triangles have to be similar but all similar triangles need not be congruent......the ratio of corresponding sides,AB/A'B'=BC/B'C'=CA/C'A'. If the two triangles are congruent AB/A'B'=BC/B'C'=CA/C'A'=1
