Answer:

x = 4

y = 6

Step-by-step explanation:

3x + 4y = 36

3x + 4(-1/2x + 8) = 36

3x - 2x + 32 = 36

x + 32 = 36

x + 32 - 32 = 36 - 32

x = 4

y = -1/2x + 8

y = -1/2(4) + 8

y = -2 + 8

y = 6

Answer:

the best value is two 50 ml bottles

Step-by-step explanation:

Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =

$45 + \frac{45}{2} = 67.5$

We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !

then you can dived the volume of bottle with price ...

the price of one ml is 0.675 in first State

$\frac{67.5}{100 } = 0.675$

in the second state the price of one ml is

$\frac{55}{80} = 0.6875$

then :

$0.675 < 0.6875$

so the best value is two 50 ml bottles

zloy xaker [14]

Answer:

41.67

Step-by-step explanation:

Using the tangent on the stick with shadow:

tan(θ) = $\frac{1}{0.6}$

Using the tangent on the building:

tan(θ) = $\frac{h}{25}$

⇒ h = 25 · tan(θ)

= 25 · $\frac{1}{0.6}$

⇒ h = 41.66... ≈ 41.67
