-20 if you literally type ur problem in on the top search bar it gives u ur answer
Answer:
b = -2
Step-by-step explanation:
1) Cross multiply the proportion, in turn, you receive 2(b-4) = 6b.
2) Simply said equation, you should have 2b - 8 = 6b.
3) Subtract the 2b from each side, effectively canceling it out on the left (original position) and resulting in 6b to become 4b (6b - 2b = 4b).
4) After you have -8 = 4b, you can divide both sides by 4, canceling out on the right (original position).
5) You are finally left with -2 = b, reversing this results in b = -2.
-2 is your answer.
Answer:
![\sqrt[15]{x^7}](https://tex.z-dn.net/?f=%5Csqrt%5B15%5D%7Bx%5E7%7D)
Step-by-step explanation:
If we have the expression
, we have to think about exponent rules.
If we have 
, then the value will be equal to 
.
So simplified will be 
Converting 
and 
into fifteenths (lcm) gets us 
.
We can convert 
into a radical by taking the denominator root of x to the numerator.

Hope this helped!
Answer:
$153.75
Step-by-step explanation:
$71.75 / 7=$10.25
$10.25 x 15 =$153.75
I’m not sure what the question is but I’m just gonna assume that you need the equation: y=1/2x+5
