For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3

There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.


There should be 6 orange picks.


You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.

Solve for w. 5w + 9z = 2z + 3w
Margaret [11]

Answer:

w = -7z/2

Step-by-step explanation:

Our goal is to isolate w

1. subtract 3w from both sides to get 2w+9z = 2z

2. Subtract 9z from both sides to get 2w = -7z

3. Divide both sides by 2 to get w = -7z/2

We cannot simplify further, so this is our answer.

The denominator of a fraction in the simplest form is greater than the numerator by 1. If 4 is added to the numerator, and 3 is
Fantom [35]

Answer:

Step-by-step explanation:

Let the original fraction is: x/ x-1

And we have that:

  • 4 is added to the numerator => new numerator is: x+4
  • 3 is subtracted from the denominator => new denominator is: x -1-3 = x -4

the fraction itself is increased by 2\frac{1}{6}

<=> \frac{x}{x-1} *2\frac{1}{6} = \frac{x+4}{x-4}

<=> 7x^{2} -70x +24 = 0

Solve for X then we substitue into the original fraction

For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain.
slamgirl [31]

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8.

The complete question is

a) (f + g)(x), (b) (f – g)(x), (c) (f × g)(x), (d) (f / g)(x), (e) (f + g)(7), (f) (f - g)(2), (g) (f.g)(3), (h) (f/g)(27)

<h3>What is a Function ?</h3>

A function is the law that defines the relation between independent and a dependent variable.

It is given that

f(x) = 3x+8

g(x) = 8x-3

(a)  (f + g)(x) = 3x+8 +8x-3 = 11x+5

(b)  (f – g)(x) = 3x+8 -8x+3 = -5x +11

(c) (f × g)(x) = (3x+8)(8x-3) = 24x²-9x+64x -24 = 24x² +55x-24

(d)(f / g)(x) = (3x+8)/(8x-3)

(e) (f + g)(7) = 11*7+5 = 77+5 = 82

(f) (f - g)(2)= -5*2 +11 = 1

(g) (f.g)(3) =24*9 +55*3 -24 = 357

(h)  (f/g)(27) = (3x+8)/(8x-3)  = (3 * 27 +8)/(8*27-3) = 89/213

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8)
