the sum of the ages of petra and her mother 44. her mother is 8 years more than twice as old as petra. how old are petra and her mother.
this dont make sense so pls help me on this math question help me asap pls and ty
I just did.
If Petra is 12 then her mother must be 32 I think.
If her mother is 8 yrs more than twice as old as Petra then here is the math:
Twice as old as Petra: 12+12=24
8yrs more than twice: 24+8=32
So Petra's Mother is 32 years old.
Can u pls just tell me if my answer is correct?
P + M = 44
M = 2P + 8
P + 2P + 8 = 44
3P + 8 = 44
- 8 - 8
3P = 36
3 3
P = 12 Petras Age.
So is Petra is 12, that means her mom is 32....?
P + M = 44
M = 2P + 8
P + 2P + 8 = 44
3P + 8 = 44
- 8 - 8
3P = 36
3 3
P = 12 Petras Age.
To solve this math question, you can use algebra. Let's assign variables to the ages of Petra and her mother. Let P represent Petra's age and M represent her mother's age.
According to the problem statement, the sum of their ages is 44:
P + M = 44 Equation 1
Also, it is stated that Petra's mother is 8 years more than twice as old as Petra:
M = 2P + 8 Equation 2
To find their ages, we need to solve these two equations simultaneously:
1. Substitute Equation 2 into Equation 1:
P + (2P + 8) = 44
Combine like terms:
3P + 8 = 44
Subtract 8 from both sides:
3P = 36
Divide both sides by 3:
P = 12
2. Substitute the value of P (12) into Equation 2:
M = 2(12) + 8
M = 24 + 8
M = 32
Therefore, Petra is 12 years old, and her mother is 32 years old.
