Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!
550 ml is the original amount in addition to the 18% that was given free
We can write this as
550 = 100% + 18% = 118%
550 = 118%
The first step to working this out is to work out what 1% of the drink is equivalent to
To get from 118% to 1%, we must divide by 118
We do exactly the same to the drink
550/118 = 4.661ml
We also know that 18% was given free
4.661 x 18 = 83.898ml Free
83.9ml free
