Nora is 4 years older than Hina . If the sum of their ages is at most 45 years ,find the maximum possible age of Hina. * b) 25 years

a) 20 years

c) 15 years

choose the correct answer

a) 20 years

Step-by-step explanation:

Hina:  x

Nora:  x + 4

x + x + 4 ≤ 45

2x + 4 ≤ 45

2x ≤ 41

x ≤ 20.5

20 years old and 15 years old would be ≤ 20.5 but the question asked for maximum possible age so 20 years old it is.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

yes

step-by-step explanation:

yes
