B=3d and b=d+4 

Since b=b we can say:

3d=d+4  subtract d from both sides

2d=4  divide both sides by 2

d=2

Daniel is 2 years old.  (and Ben is 6 years old)

An employee receives a pay increase from $35,000 per year to $37,500 per year. Calculate the percent increase. Round to the near
arsen [322]

Answer:

The percentage increase in salary of employee is 7.14 %  

Step-by-step explanation:

Given as :

The initial pay of employee = $35,000 per year

The increase pay of employee = $37,500 per year

Let The percentage increase in salary =  X %

So, X  = \frac{increase salary - initial salary}{initial salary}  × 100

Or, X  = \frac{$37,500 - $35,000}{$35,000}  × 100

Or,  X  = \frac{$2,500}{$35,000}  × 100

∴     X = 0.0714  × 100  = 7.14 %

Hence The percentage increase in salary of employee is 7.14 %   Answer

Answer: 16⅔ yds by 25 yds

Step-by-step explanation:

Let x be the length of 3 fence sections

Let y be the length of 2 fence sections

A = xy

3x + 2y = 100

y = 50 - 1.5x

A = x(50 - 1.5x) = 50x - 1.5x²

dA/dx = 50 - 3x

       0 = 50 - 3x

      3x = 50

        x = 50/3 = 16⅔ yds

        y = 50 - 1.5(16⅔) = 25 yds

Solve the following quadratic function by using the quadratic formula: x^2 +<br> 2x - 1 = 2 *
elena55 [62]

Answer:

x = 1 or x = -3

Step-by-step explanation:

ax^{2} + bx + c = 0

x = \frac{-b±\sqrt{b^{2}-4ac } }{2a\\}

as x^{2} + 2x - 1 = 2 ⇔  x^{2} + 2x - 3 = 0, its solution is

x = \frac{-2±\sqrt{2^{2}-4 *1*(-3)} }{2*1}

=  \frac{-2±\sqrt{4+12} }{2} =  \frac{-2±\sqrt{16} }{2} =  \frac{-2±\ 4 }{2}

therefore, x = 1 or x = -3

hope this helps! :D

have a miraculous day, and brainliest is immensely appreciated!! <3
