Answer:
There are <u>35 boys</u> in the class.
Step-by-step explanation:
Girls to Boys ratio = 3:7
Total number of students in class = 50
Let total number of girls be '3x' and total number of boys be '7x'
Total number of girls + Total number of boys = Total number of students
3x + 7x = 50
10x = 50
x = 50/10
x = 5
Total number of girls = 3 × 5 = 15
Total number of boys = 7 × 5 = 35
The explicit formula is B
Answer: x = 3
Step-by-step explanation:
5x - 1 + 14 - original equation
5x = 15 - add 1 to both sides
x = 3 - divide both sides by 5
