Answer:

x = (ab +a +b +c)/(a +b)

Step-by-step explanation:

Eliminate parentheses, subtract left terms not containing x, divide by the coefficient of x.

$a(x-b)+bx-c=a+b\\\\ax+bx-ab-c=a+b\\\\x(a+b)=ab+a+b+c\\\\\boxed{x=\dfrac{ab+a+b+c}{a+b}}$

A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be d

german

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

$\dfrac{x}{8000}=\dfrac{3}{125}$

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

$x=\dfrac{3}{125}(8000)$

$x=0.024(8000)$

$x=192$

So around 192 cell phones are expected to be defective out of 8000 phones.

Answer:

3 months

Step-by-step explanation:

We don't know what's on your list of "useful financial formulas." One that can be used here is the formula for simple interest:

I = Prt . . . . . interest on principal P at annual rate r for t years

Solving for t gives ...

t = I/(Pr)

Filling in the given values, we can find t to be ...

t = 138/(4800×0.115) = 138/552 = 1/4

1/4 year is 3 months -- the duration of the loan.

ASNWER CORRECTLY AND YOU WILL GET 40 POINTS ALONG WITH BRAINLIEST

FromTheMoon [43]

Answer:

Step-by-step explanation:

What we know:

ABD is a straight angle, it measures 180 degrees
Angle CBA + CBD = 180 degrees
Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9 /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°
