Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    84-(4*(1-4*g))=0

 84 -  4 • (1 - 4g)  = 0

3.1     Pull out like factors :

  16g + 80  =   16 • (g + 5)

16 • (g + 5)  = 0

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

4.2      Solve  :    g+5 = 0  

Subtract  5  from both sides of the equation :  

                     g = -5

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

84 = 4(1 - 4g)

<u>Step 2: Solve for </u><em><u>g</u></em>

  1. Distribute 4:                    84 = 4 - 16g
  2. Isolate <em>g</em> term:                 80 = -16g
  3. Isolate <em>g</em>:                         -5 = g
  4. Rewrite:                           g = -5

<u>Step 3: Check</u>

<em>Plug in g into the original equation to verify it's a solution.</em>

  1. Substitute in <em>g</em>:                    84 = 4(1 - 4(-5))
  2. Multiply:                               84 = 4(1 + 20)
  3. Add:                                     84 = 4(21)
  4. Multiply:                               84 = 84

Here we see that 84 does indeed equal 84.

∴ g = -5 is a solution of the equation.

You are choosing between two different cell phone plans. The first plan charges a rate of
Zolol [24]

Answer:

at least 450 minutes

Step-by-step explanation:

Find an expression for the cost of each plan as a function of the number of minutes. Set the expressions equal to each other, and solve for the number of minutes.

Let x = number of minutes.

First plan:

cost (in dollars) = 0.21x

Second plan:

cost (in dollars) = 0.11x + 44.95

Set the expressions equal:

0.21x = 0.11x + 44.95

Subtract 0.11x from both sides.

0.1x = 44.95

Divide both sides by 0.1

x = 44.95/0.1

x = 449.5

Since you cannot have a fraction of a minute, the answer is 450 minutes.

a circus charges $2.50 for kids tickets and $6 for adult tickets last week and twice as many kids attended the circus than adult
aliina [53]
Let
x-----------> the number of kids
y----------> the number of adults

we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300

the answer is
the number of kids is 1300

Demarco has a piece of fabric 6yd long. He uses a piece 3yd long. He cuts the rest into strips that are each 3\4 yd long. How ma
Kobotan [32]

Answer: 4

Step-by-step explanation:

Hi, to answer this question, first, we have to subtract the amount of fabric used (3yd) to the total fabric that Demarco has (6yd)

6 -3 =3yd

Finally, we have to divide the result by the length of each strip piece (3/4yd)

3÷ 3/4= 4 pieces  

There are 4 3/4 yd long strips.

Feel free to ask for more if needed or if you did not understand something.

faltersainse [42]

Answer:

\left\{\begin{matrix}39 & x\leq 200\\ 39+(x-200)\times 0.35 & x>200\end{matrix}\right.

Step-by-step explanation:

We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.

We are also told that For any minutes over 200, Ben is charged $0.35 per minute.

let x  be the minutes used each month

So, if x\leq 200

So, coat will be $39

If x>200

So, Ben is charged $0.35 per minute

So, when x>200

So, charge = 39+(x-200)\times 0.35

So, the piecewise functions accurately represents charges based on Ben's cell phone :

\left\{\begin{matrix}39 & x\leq 200\\ 39+(x-200)\times 0.35 & x>200\end{matrix}\right.
