Let the triplets' age be x, the sister's age is then x-5.
product of their age as given
xÂł.(x-5)=75749+x+x+x+x-5
x^4 - 5xÂł= 4x +75744
x^4 - 5xÂł -4x -75744=0
resolving the equation,
we get
x = 18
therefore, Age of ben,bob and bill is 18
so , age of stephanie is x-5 = 18-5 = 13
stephanie is 13 years old.
In this question, the algebra equation is a[3(5b - c)]. Since a = 1.6, b = 2, and c = 5, we would replace the equation into 1.6[3((5)(2) - 5)).
With this equation, the answer will be 24
50,5-100%
40,4-х%
x=(40,4*100)\50,5=80%
Answer:80%
Answer:
y = -24
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
12 = k*(-1)
12/(-1) =k
-12 = k
The equation is y = -12x
Let x = 2
y = -12(2)
y = -24
First, you calculate the total amount of parts : 7 + 3 = 10
Next, divide the number by the total amount of parts : £500 ÷ 10 = £50
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : £50 × 3 = £150 and £50 × 7 = £350
Finally put these answers back into the ratio : £150:£350
To check, make sure both sides of the ratio add up to the original number : £150 + £350 = £500
