Answer:
Step-by-step explanation:
First off, this wouldn't make sense for a girl to be older than her mother or her father.
Second, mother is x years old. The girl is 2x years old. The father is x+5 years old. Total sum = 100.
So, we need to solve for x first.
2x + x + x+5 = 100
4x + 5 = 100
4x = 95
4x ÷ 4 = 95 ÷ 4
x = 23.75
Mother is 23 and 3 quarters, turning 24.
Daughter is 23.75 × 2 = 47 1/2 years old.
And the Father is 28 and 3 quarters, turning 29.
Answer:
156 [in²].
Step-by-step explanation:
1) total area consists of six parts (all the details are in the attachment):
A=2A₁+2A₂+A₃+A₄;
2) according to the formula above:
A=2*5*3+2*0.5*(6+12)*4+6*3+12*3=156 [in²].
-3(4-2y)=24
Apply distributive property
-12+6y=24
Add 12 to both sides
6y=36
Divide both sides by 6
y=6
98.4252<span> inches is the exact so about 98 inches</span>
