- 4/15
Step-by-step explanation:
Just take 4 and 15 make that a fraction make the fraction a negative not the 15 because they will be the same thing no matter where you place it
Answer:
II. One and only one solution
Step-by-step explanation:
Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Let assume the equation is given as;
x + 3y = 11 .... 1
x - y = -1 ....2
Using elimination method
Subtract equation 1 from 2
(x-x) + 3y-y = 11-(-1)
0+2y = 11+1
2y = 12
y = 12/2
y = 6
Substitute y = 6 into equation 2:
x-y = -1
x - 6 = -1
x = -1 + 6
x = 5
Hence the solution (x, y) is (5, 6)
<em>Hence we can say the equation has One and only one solution since we have just a value for x and y</em>

The best choice is A)
when you add a zero, it does not count on a decimal, so,
1.9, 1.90, 1.900.
2/3÷4/5
2/3*5/4
10/12
5/6
Hope this helps :)
