She earned 145$ a day because 725/5 is 145
Answer:
<em>t</em>=2d/s
Step-by-step explanation:
Combining Expressions and isolating the variable <em>t</em>
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.

Beginning with an "If-then" statement ⇣
<em>If </em><em>2/5 = 30 </em><em>then</em><em> 1/5 = 15</em>
Now we have 1/5, let's make it 1 by multiplying x5.
<em>15 x 5 = </em><em>75</em>

Good luck! :)
