Answer:
30 years
Step-by-step explanation:
Forming Algebraic expressions and solving them to find the age.
Ratio of age of mother and daughter = 5 : 3
Age of mother = 5x
Age of daughter = 3x
It is given that mother's age is 50 years.
⇒ 5x = 50
Divide both sides by 5.
x = 50÷5
x = 10
Daughter's age = 3x
= 3*10
= 30 years
Answer:
15 1/240
Step-by-step explanation:
ok so he is owing his sister 24 and he gives her 15
so 24-15=9
but as an addition expression it will be
x+15=24
x=24-15
x=9

Answer:
∠LMN = 105°
Step-by-step explanation:
Quadrilateral LMNO is a parallelogram in which ∠L = 25x° and ∠MNO = (22x + 9)°
We have get the measurement of ∠LMN
Since in a parallelogram opposite angles are equal.
Therefore 25x = 22x + 9
25x - 22x = 9
3x = 9
x = 3
From another property of a parallelogram we know that consecutive angles are supplementary.
∠LMN + ∠ONM = 180°
∠LMN = 180 - ∠OLM = 180 - (25x) = 180 - (25×3)
∠LMN = 180 - 75 = 105°
Answer is ∠LMN = 105°
