Answer:

-5

Step-by-step explanation:

6u+7u-16=-81

Carry over the "-16" and make "u" the subject.

6u+7u= -81+16

13u= -65

Carry over the "13" and make "u" the subject

u= -65/13

u= - 5

Answer:

6u+7u-16=-81

We simplify the equation to the form, which is simple to understand

6u+7u-16=-81

We move all terms containing u to the left and all other terms to the right.

+6u+7u=-81+16

We simplify left and right side of the equation.

+13u=-65

We divide both sides of the equation by 13 to get u.

u=-5

Answer:

D. -19/2

Step-by-step explanation:

Well, we know that R is greater than Y and that at the midpoint, R is 10.5, so Y can't be greater than this (c, 13) and that it isn't the same (b, 10.5). It could either be -8 or -19/2 (which is -9.5). Being that your first coordinate is in fraction form, the second one would also have the be, making the answer D. -19/2
