Well, we know that the total amount is $420, so we can already set one side of the equation. =420. Also, it said that the $420 is (equal to) 7/6b (b for balance).
Now just put it together! 7/6b=420 is your answer.
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7

Answer:
Domain:![[-1,0]\cup [1,\infty )](https://tex.z-dn.net/?f=%5B-1%2C0%5D%5Ccup%20%5B1%2C%5Cinfty%20%29)
Step-by-step explanation:
Since we know that a square root function is not defined for negative numbers. In order our function to be defined values inside radical must be greater than or equal to zero.
Our function will be defined when


or 
Now we will use number line method of solving inequalities to check whether our answer is right or not.
Let us try -2, -1/2, 1/2 and 2 to check which conditions meet our criteria.






Therefore, we can see that our function is defined when
or
and domain of f(x) is
.
