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:
100
Step-by-step explanation:
150 divided by 3 is 50. So that means one third of 150 is 50. Subtract 50 from 150 and you're left with 100.
Answer: Lottie saved 330 pounds.
Step-by-step explanation:
Lottie's amount can be represented by the expression x + 76 and Kai's amount is unknown so we will also represent by x.
We know that the combination of their savings will be 584 pounds so we will add the expression and set them equal 584.
x + (x + 76) = 584 Now solve for x
2x + 76 = 584
-76 -76
2x = 508
x= 254
If x was Kai's amount then Kai save 254 pounds.
Lottie saved 76 more that Kai
254 + 76 = 330
Lottie also save 330 pounds
