Answer:
x=3
Step-by-step explanation:
8x-28-2x=-10
We move all terms to the left:
8x-28-2x-(-10)=0
We add all the numbers together, and all the variables
6x-18=0
We move all terms containing x to the left, all other terms to the right
6x=18
x=18/6
x=3
To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800 /:350
x=108
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
Y + 2 = 1/5(x - 1)
y + 2 = 1/5x - 1/5
y = 1/5x - 1/5 - 2
y = 1/5x - 1/5 - 10/5
y = 1/5x - 11/5
slope = 1/5
y int = (0,-11/5)....for graphing purposes, -11/5 = - 2 1/5
x int = (11,0)

Answer:
20%
Step-by-step explanation:
100 mL of the drink is coffee
The total amount of drink is 100 mL +400 mL = 500 mL. Then the fraction that is coffee is ...
coffee/total = (100 mL)/(500 mL) = 1/5 = 1/5 × 100% = 20%
20% of Donna's drink is coffee.
