The ratio of boys to girls in a group is 5:2. If there are 24 more boys than girls, work out how many boys there are.

40 boys

Step-by-step explanation:

we can make use of the ratio and the number of boys.

give the girls a variable ---x

use cross multiplication:

5          :        2

24 + x   :       x

the 24 + x means there are 24 more boys than girls

5x = 2 ( 24 +x)

5x = 48 + 2x

5x - 2x = 48

3x = 48

x = 16

the number of girls are 16 .

the number of boys are:

16 + 24 = 40

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

i think is g(1)=-1.

hope that i can
