  1. Use the number line below, where RS=5y +5, ST = 2y + 5, and RT= 66.The value of y=8,the value of RS=45, and ST=21.
    What is Number Line?
    • In math, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.
    • A number line can be extended infinitely in any direction and is usually represented horizontally.
    • The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
    • A number line can also be used to represent both positive and negative integers as well.
    • Writing numbers on a number line make comparing numbers easier. The numbers on the left are smaller than the numbers on the right of the number line.
    • A number line can also be used to carry out addition, subtraction, and multiplication. We always move right to add, move left to subtract, and skip count to multiply.
    RS=5y +5
    ST = 2y + 5
    RT= 66
    RS+ST=RT
    (5y +5)+(2y + 5)=66
    7y+10=66
    7y=66-10
    7y=56
    y=8
    RS=5y +5,
    put value of y in these question.
    RS=5(8)+5
    RS=45
    ST = 2y + 5,
    put value of y in these question.
    ST = 2(8)+ 5
    ST=21
