Answer:

x = 25, The angles of the triangle are 60*, 45*, and 75*.

Step-by-step explanation:

The sum of the angle measure is 180 so we can form this equation:

60 + (x + 20) + 3x = 180

Now isolate the variable to find x.

(x + 20) + 3x = 120

4x + 20 = 120

4x = 100

x = 25

Now solve for the angles of the triangle.

3(25) = 75

(25 + 20) = 45

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

Which is greater than or less than

poizon [28]

Answer:

C. -2/3 < -0.8

F. -3/5 < -0.35

Therefor, -2/3 is less than -0.8.

And, -3/5 is also less than -0.35.

Also, you could turn the fractions into decimals to make your life easier for example, -3/5 into decimal form is -0.6.

And -2/3 into decimal form is -0.6666
