(x+12) (3x+2)
Find the value of X

Answers

Answer 1

Step-by-step explanation:

Equation at the end of step 1

(3x2 - 38x) + 24 = 0

STEP2:Trying to factor by splitting the middle term

 2.1     Factoring  3x2-38x+24 

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -38x  its coefficient is  -38 .

The last term, "the constant", is  +24 

Step-1 : Multiply the coefficient of the first term by the constant   3 • 24 = 72 

Step-2 : Find two factors of  72  whose sum equals the coefficient of the middle term, which is   -38 .

     -72   +   -1   =   -73     -36   +   -2   =   -38   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -36  and  -2 

                     3x2 - 36x - 2x - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                    3x • (x-12)

              Add up the last 2 terms, pulling out common factors :

                    2 • (x-12)

Step-5 : Add up the four terms of step 4 :

                    (3x-2)  •  (x-12)

             Which is the desired factorization

Equation at the end of step2:

(x - 12) • (3x - 2) = 0

STEP3:Theory - Roots of a product

 3.1    A product of several terms equals zero. 

 When a product of two or more terms equals zero, then at least one of the terms must be zero. 

 We shall now solve each term = 0 separately 

 In other words, we are going to solve as many equations as there are terms in the product 

 Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

 3.2      Solve  :    x-12 = 0 

 Add  12  to both sides of the equation : 

                      x = 12

Solving a Single Variable Equation:

Answer 2

Step-by-step explanation:

[tex]if \: (x + 12) = (3x + 2) \\ 12 - 2 = 3x - x \\ 2x = 10 \\ x = 5 \\ \\ \\ if(x + 12)(3x + 2) = 0 \\ x + 12 = 0 \: \: \: or \: \: \: 3x + 2 = 0 \\ x = - 12 \: \: \: or \: \: \: x = - \frac{2}{3} [/tex]

A company rents out 17 food booths and 21 game booths at the county fair. The fee for a food booth is $75 plus $10 per day. The fee for a game booth is $95 plus $4 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.

Answers

Answer:

Food booth= (75+10d)17

Game booth= (95+4d)21

Step-by-step explanation:

GAME BOOTH

$95 initial fee plus $4 per d amount of days

f(x)=95+4d

Multiply the expression by 21 because you have 21 game booths

FOOD BOOTH

$75 initial fee plus $10 per d amount of days

f(z)=75+10d)

multiply this expression by 17 because their are 17 food booths

A bakery sold 145 chocolate cupcakes in a day, which was 29% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?

Answers

Answer:

500 cupcakes

Step-by-step explanation:

Given that the 145 cupcakes is 29% of the total number of cupcakes sold that day,

29% --- 145 cupcakes

The total number of cupcakes sold would be 100%.

1% --- 145 ÷29= 5 cupcakes

100% --- 100(5)= 500 cupcakes

Thus, the bakery sold 500 cupcakes that day.

Answer:

Step-by-step explanation:

500 cupcakes

Step-by-step explanation:

Given that the 145 cupcakes is 29% of the total number of cupcakes sold that day,

29% --- 145 cupcakes

The total number of cupcakes sold would be 100%.

1% --- 145 ÷29= 5 cupcakes

100% --- 100(5)= 500 cupcakes

Thus, the bakery sold 500 cupcakes that day.

.Ray's Rental Car Company charges a $50 rental fee, $15 for gas and $0.25 per mile driven. For the same car, Rosie's Rental Car Company charges $40
for rental and gas and $0.35 per mile driven. At what mile do the companies charge the same amount?

Answers

Answer: 166.667 miles

Step-by-step explanation:

For the first company, the cost can represented by the equation: y=0.25m +50+15

Which is the same as y=0.25m +65

For the second company, the cost can represented by the equation:0.35m+40

m is the miles driven

To find at after how many miles they cost the same, I will set both equations equal to each other to solve for m

0.25m+65=0.35m+40

-0.25m -0.25m

65=0.15m+40

-40 -40

25=0.15m. Divide both sides by 0.15

166.667=m

So after 166.667 miles, the companies charge the same.

You can also round it again: 166.67 or 166.7 or 167

5|2x - 3| + 4 = 9
How do you solve this

Answers

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

Please correct me if I'm wrong.
