Answer:
Given - Ratio of boys to girls is 3 : 1
Total 36 students
To find - No. of girls
Solution
Let the ratio be 3x and X
3x + X = 36
4x = 36
x = 36/4
x= 9
1x = 9
There are 9 girls in the class
There are infinite parrallel lines to each line
a line is parrallel to a line if and only if there slopes are equal.y=4x+5,m=4,so any line with the equation y=4x+b where b is a real number except -5 is parrallel to y=4x-5.
D (5x9)x because the parentheses are switched but the values are the same
5 ) 8 × x = 72
6) length = 9m
Step-by-step explanation:
5.
8 × x = 72 ( area of rectangle = l×b)
6. solving the equation
8 × x = 72
x = 72 / 8
x = 9 m
length = 9m
