Rajan and Katrina both have Twitter accounts. Rajan has 43 tweets and makes 4 tweets per day. Katrina has 22 tweets and makes 7 tweets per day. After how many days will they have the same
number of tweets? How many tweets will they have?

7 days; 71 tweets

Step-by-step explanation:

You want to write this as a equation so you can find when they will meet. So it'll be something like this:

22+7x=43+4x

Get like terms together

21=3x

x=7. so it'll take 7 days

plug it back in to find the number of tweets

71=71

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
