Answer:
72 yrs old.
Step-by-step explanation:
The combined age
D+O=96
The owner is 3 times older than dog
O=3D
D+3D=96
4D = 96
D= 24
Now substitute the value of D in O=3D
O=3.24= 72
The owner is 72 years old.
Answer:
A=B
Step-by-step explanation:
Equation 1: 70% of A = 0.7a
Equation 2: 35% of B = 0.35a
Equation 3 = (Equation 2) • 2
Equation 3: 70% of B = 0.7a
Equation 3 = Equation 1
A = B

Answer:
(13/10)H
got it on khan academy brainliest pls thx uwu
Remember that 30% in fraction form is 33/100
The amount of health points (H) restored would depend on the amount of the current H so it means it would add 30% of the current which we can write as:
(30/100)H
And since it would add that to the current total we can right the current total as:
(100/100)H
So our equation would be
=(30/100)H + (100/100)H
=(130/100)H
=(13/10)H
