There are 364 first-grade students in Park Elementary School. If there are 26 more girls than boys, how many girls are there?
wlad13 [49]

Answer:

195

Step-by-step explanation:

If there are x boys, then there are x+26 girls. Hence, we write the equation,

x+(x+26)=364

Solve for x:    

        2x+26=364

            2x-338

             x=169

So there are 169+26 =195 girls

if veretx angle=z then
84+z=180
