Answer:

60 = a

Step-by-step explanation:

⅔ of 30 is 20; ½ of 60 is 30. So together, you have <em>30</em><em> </em><em>+</em><em> </em><em>20</em><em> </em><em>=</em><em> </em><em>50</em>.

I am joyous to assist you anytime.

1/2a + 2/3(30)= 50
1/2a + 20 = 50
1/2a= 50-20
1/2a= 30
A= 30(2)
A= 60

The solution is 60.

Hope this helps!

PLS HELP I DONT UNDERSTAND!!<br> What type of circle would you use when graphing x≥5
inna [77]

How to:

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

For this problem:

For the number line, we would place a solid dot at −5 because the value is both greater than and equal too (≥) and then continue a line on the number line to the right of that point incorporating all values greater than −5

Answer:

<em><u>(image attached) </u></em>

<em><u>Look at the one showing your problem, the first one.</u></em>

<em><u>It's reverse of that since X is greater meaning the line goes the other way instead as shown in the second image.</u></em>
