X would represent time(days)
11 is Tommy total of picture while 15 is Elizabeth total of pictures


Part B

11x+15x
Since we want to find how much in 7 days we plug in 7 for x

11(7)+15(7)
77+105=182

Altogether they would have posted 182 pictures after 7 days

Multiple choice!!!!!!!!!!!!!!!!!!
dolphi86 [110]
By the external angle theorem 

5x = (5x - 30) +  m < RST

m < RST  = 5x - 5x + 30  = 30

 also m < STR = m < SRT = 5x - 30

So as there are 180 degrees in a triangle:-

5x - 30 + 5x - 30 + 30 = 180

10x = 180 +30+30-30 = 210

x = 21 answer

Answer:

\frac{ \sqrt{5x} }{5x}

Step-by-step explanation:

\frac{1}{ \sqrt{x5} }

=  \frac{1}{ \sqrt{5x} }

=  \frac{1}{ \sqrt{5x} }  \times  \frac{ \sqrt{5x} }{ \sqrt{5x} }

=  \frac{1 \sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }

=  \frac{\sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }

= \frac{ \sqrt{5x} }{5x}
