Angles ABD and DBC are supplementary. They are also a linear pair because they share a ray. Supplementary angles add up to equal 180, as do linear pairs. Therefore, from our picture, 7x + x - 4 = 180. 8x = 184. Therefore, x = 157. 157-4 = ∠DBC, so ∠DBC = 153.

What is the value of the expression below when x<br> 3 and y = 8?<br> 6x + 10y

suter [353]

Answer:

98

Step-by-step explanation:

So we have the expression:

$6x+10y$

And we want to evaluate it when x is 3 and y is 8.

So, substitute:

$=6(3)+10(8)$

Multiply:

$=18+80$

Add:

$=98$

And we're done!
