Answer:
18 years
Step-by-step explanation:
let the boy's age my x and mother's age be y
x+y=48
y=3+2x which can also be written as 2x-y=-3
on solving both the equations,
you will get x=15 and y=33
so son's age is 15 years and mom's age is 33 years and the difference between their ages is 18
Answer:
y = 16
Step-by-step explanation:
6y - (6 + 4y) = 26
6y - (6 + 4y) = 2y - 6
2y - 6 = 26
+6 +6
-------------------
2y = 32
/2 /2
-------------------
y = 16
I think it is the mean and the range thats what i think
28/11.2 = 2.5
since they are similar and openly stated as parrallelograms, you know that they have a scale of the longest edge of EFGH to the longest edge of JKLM
