The ratio of boys to girls in a group is 7:1. If there are 54 more boys than girls, work out how many boys there are.

63 boys

Step-by-step explanation:

Given that the ratio of boys : girls = 7 : 1 = 7x : x ( x is a multiplier ), then

7x = x + 54 ( 54 more boys than girls )

Subtract x from both sides

6x = 54 ( divide both sides by 6 )

x = 9, hence

number of boys = 7x = 7 × 9 = 63

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
