Answer:
91 boys
Step-by-step explanation:
Given that the ratio of boys to girls = 7 : 2 = 7x : 2x ( x is a multiplier )
There are 65 more boys than girls , thus
7x = 2x + 65 ( subtract 2x from both sides )
5x = 65 ( divide both sides by 5 )
x = 13
There are 7 × 13 = 91 boys in the group

Slope intercept form:
The equation of straight line is given by:
....[1]
where, m is the rate or slope and b is the initial value of y-intercept.
As per the statement:
A certain species of tree grows an average of 3.1 cm per week.
Let x be the number of week and y represents the weekly height of the tree.
then;
" tree grows an average of 3.1 cm per week." translated to 3.1 x
It is also given that:
the measurements begin when the tree is 400 centimeters tall.
⇒y(0) =b = 400 cm
Substitute the given values in [1] we have;
Therefore, an equation for the sequence that represents the weekly height of this tree in centimeters is,
