Is (1,3) a solution to this system of equations?4x+5y=19x+5y=16

Yes

Step-by-step explanation:

4x+5y=19

x+5y=16

4(1)+5(3)=4+15=19

1+5(3)=1+15=16

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

only 10/60 isn't equivalent

hope this : )
