a) An expression in terms of x for how many apples Ron has 3x
b) An expression in term of x for how many apples Kim has 3x - 4
c) x = 5
d) John = 5 apples, Ron = 15 apples, Kim = 11 apples
Step-by-step explanation:
a) Number of apples John has = x
Number of apples Ron has = 3 times as many apples as john
Number of apples Ron has = 3(x)= 3x
An expression in terms of x for how many apples Ron has 3x
b) Number of apples Kim has = 4 fewer apples than Ron
Number of apples Kim has = Number of apples Ron has - 4
Number of apples Kim has = 3x - 4
An expression in term of x for how many apples Kim has 3x - 4
c) Number of apples Kim has = 11
The expression in term of x for how many apples Kim = 3x - 4
equating both:
11 = 3x - 4
The equation:
3x - 4 = 11
3x = 11 + 4
3x = 15
x = 15/3
x = 5
d) We have been told Kim has 11 apples
x = 5
This means John has 5 apples
Number of apples Ron has = 3x = 3(5)
Number of apples Ron has = 15
John = 5 apples
Ron = 15 apples
Kim = 11 apples
