1. Mary has 5 apples, 7 bananas and 6 pears. Martin has 8 apples, 5 bananas and 10 pears. They let a stand for
the number of apples, b for the number of bananas and p for the number of pears. They put their fruit together and
represented it with the expression 5a + 7b+ 6p+ 8a + 5b 10p. After they combine their fruit, what would the
coefficient of b be?
The coefficient of b is 12
The coefficient of b is 13
1 point
c. The coefficient of b is 41
d The coefficient of bis 16


  1. Answer:
    Step-by-step explanation:
    Let “x”, “y” and “z” be the cost pf one apple, one banana, and one pear.
    5x + 6y =  8y + 9z
    5x + 6y – 8y  =  9z
     5x – 2y  =  9z  —(1)
    Given that :
    One apple costs as much as 2 pears.
    x  =  2z
    Applying the value of x in (1), we get
    5(2z) – 2y  =  9z
    10z – 9z  =  2y
    z  =  2y
    The cost of 1 pear is equal to 2 bananas.
