Hey there! :D

So, those both will be equal to 180 degrees. Consecutive angles are supplementary. 

2x-20+3x= 180

5x-20=180

Add 20 to both sides.

5x=200

x= 40

I hope this helps!

2x-20+3x=180
Add like terms
5x-20=180
Add 20 on both sides
5x=200
Divide by 5 on both sides
X=40

Adante begins to evaluate the expression 3 1/3 * 5 1/4
goldenfox [79]

For this case we must find the product of two mixed numbers:

3 \frac {1} {3} = 3 + \frac {1} {3} = \frac {9 + 1} {3} = \frac {10} {3}\\5 \frac {1} {4} = 5 + \frac {1} {4} = \frac {20 + 1} {4} = \frac {21} {4}

So, we have:

\frac {10} {3} * \frac {21} {4} = \frac {10 * 21} {3 * 4} = \frac {210} {12} = \frac {105} {6} = \frac {35} {2}

If we go to a mixed number we have:

\frac {35} {2} = 17 \frac {1} {2}

Answer:

17 \frac {1} {2}

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3.
frez [133]

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

<h3>---------------------------</h3>

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is <u>0.3</u>

<u>Hope this helped!</u>
