Answer:
41
Step-by-step explanation:
The entire angle is 90 degrees. So, you make the two equations add up to 90
6x+5+8x+1=90
combine like terms
14x+6=90
subtract 6 from 90
14x=84
divide by 14
x=5
then, plug 5 into angle DBC equation
6(5)+5
=41
Answer: y=9

both points have 9 as the y coordinate
Answer: The store owner makes 280 packages.
Step-by-step explanation:
25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
