Answer:
6x-7y=17-----y=6/7x-17/7
6x-11y=-13----y=6/11x-13/11
6x-11y=13----y=6/11x+13/11
11x-6y=13-----y=11/6x-13/6
Step-by-step explanation:
<span>The first equation is a direct variation. This type of equation has a form that is "y = kx," in which k is the constant. Changing both sides by a common multiple will still lead to the equation being evaluated as true, since the values will both increase by that multiple.</span>
Answer: r=6
Step-by-step explanation:
Because if 42 equals 7 times r you just have to divide 42 by 7.
