Answer:

$b = \frac{r - ax}{x} \\$

Step-by-step explanation:

$r = x(a + b) \\ r = ax + bx \\ r - ax = bx \\ \frac{r - ax}{x} = b$

hope this helps

Answer:

B = R/x -A

Step-by-step explanation:

$\text{Divide the equation by x:}\\\\\dfrac{R}{x}=A+B\\\\\text{Subtract A:}\\\\\dfrac{R}{x}-A = B\\\\\text{The solution is ...}\\\\\boxed{B=\dfrac{R}{x}-A}$

Answer:

The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: $-2(bx-5)=16$

First we need to find

The value of x in terms of b

We need to find value of x

$-2(bx-5)=16$

Multiply -2 with terms inside the bracket

$-2bx+10=16$

Subtract 10 from both sides

$-2bx+10-10=16-10\\-2bx=6$

Divide both sides by -2b

$\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}$

So, The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3

We have the equation for the value of x in terms of b:

$\mathbf{x=-\frac{6}{2b}}$

Put b = 3

$x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1$

So, The value of x when b is 3 is: x = -1

Answer:

Area of circle R = 75π un² or ≈235.5 un²

Step-by-step explanation:

The problem says that m∠TRS = 120º. The total number of degrees in a circle is 360º. 120º is a third of 360º. Therefore, we can prove that the shaded sector is a third of the circle.

The problem then says that the area of the shaded sector is 25π and we have to calculate the area of the entire circle. Since we already know that the shaded sector is a third of the circle, we can simply multiply 25π by 3 in order to calculate the area of t he entire circle.

25π × 3 = 75π.

Area of circle R = 75π un² or ≈235.5 un²
