1).  Subtract  2a  from each side.        2a - 3  =  7

2).  Add  3  to each side:                       2a        =  10

3).  Divide each side by  2 :                  <em>  a        =  5</em>

kondaur [170]
Hello :
tan²(θ) = 3.. equi : tan(θ) = √3  or tan(θ) = -√3
1 ) tan(θ) = √3
tan(θ) = tan(<span>π/3)
</span>θ = π/3 +kπ  k in Z
2)tan(θ) = -√3
tan(θ) = tan(-π/3)
θ = -π/3 +kπ  k in Z

The ratio of boys to girls in a class is 4:3. there are 9 girls. how many boys are in the class?
aalyn [17]
For every 3 girls, there are 4 boys. if there are nine girls, that expands to three extra boys, because for every three theres an extra one. so there are 12 boys (9+3.) the final ratio, boys to girls, is 12:9.
