12b - 4 = 12 + 2(b+1)

2 × b = 2b

2 × 1 = 2

12b - 4 = 12 + 2b + 2
+ 4 +4

12b = 12 + 2b + 2 + 4
-2b -2b

10b = 12 + 2 + 4

10b = 18
÷10 ÷ 10

b = 1.8

There you go! I really hope this helped, if there’s anything just let me know! ☻

12b - 4 = 12 + 2(b + 1)

12b - 4 = 12 + 2b +2

12b - 4 = 14 + 2b

      + 4 =+ 4


12b = 18 + 2b

-2b =      -2b


10b = 18

----- = ----

The point (-4‚-2) lies on a circle. What is the length of the radius of this circle if the center is located at (-8‚-10)
MAVERICK [17]

Answer:

<em>4√5</em>

Step-by-step explanation:

The length of the radius of the circle will be the distance between the two coordinates. Using the formula:

D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates (-4‚-2) and (-8‚-10)

R = √(-8-(-4))²+(-10-(-2))²

R = √(-4)²+(-8)²

R = √16+64

R = √80

R = √16*5

R = 4√5

<em>Hence the  length of the radius of this circle is 4√5</em>

You work for a dress makers and your boss sends you to the fabric store to buy yellow fabric. She tells you to buy the best deal
finlep [7]

Answer:

D) 35 yards for $90.

Step-by-step explanation:

We have been given four options and we are asked to choose the option that represents the best deal.

Let us find the cost of per yard cloth for our given choices.

A. \text{ Price offered by option A}=\frac{\$20}{5\text{ yards}}

\text{ Price offered by option A}=\frac{\$4}{\text{ yard}}

Therefore, option A offers $4 per yard of cloth.

B. \text{ Price offered by option B}=\frac{\$30}{10\text{ yards}}  

\text{ Price offered by option B}=\frac{\$3}{\text{ yard}}  

Therefore, option B offers $3 per yard of cloth.

C. \text{ Price offered by option C}=\frac{\$55}{20\text{ yards}}  

\text{ Price offered by option C}=\frac{\$2.75}{\text{ yards}}  

Therefore, option C offers $2.75 per yard of cloth.

D. \text{ Price offered by option D}=\frac{\$90}{35\text{ yards}}  

\text{ Price offered by option D}=\frac{\$2.57}{\text{ yard}}  

Therefore, option D offers $2.57 per yard of cloth.

Since price offered by option D is less than other option D is the best deal.

A candle on pauline’s dresser is 10 inches tall and burns at a rate of 0.75 inches per hour. how many hours will it take for the
Natalija [7]

Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:

h(t) = 10 - 0.75t

The height will be of 0.25 inches when h(t) = 0.25, hence:

0.25 = 10 - 0.75t

0.75t = 9.75

t = 9.75/0.75

t = 13 hours.

Jose bought 750 bags of peanuts for $375.00.he intends to sell each bag for $0.15 more than he paid. How much should he charge f
tatyana61 [14]

Jose should charge $0.65 for each bag if he intends to sell the bag for $0.15 more than he paid.

<h3>How do we solve word problems?</h3>

Mathematical problems dealing with word problems can be solved by arranging data given into variables and using the appropriate arithmetic operation to solve them.

From the given information:

If Jose bought a 750 bag of peanuts for $375.00. It means that he bought each bag(1 bag) for:

\mathbf{=\$\dfrac{375}{750}}

= $0.5

However, he intends to sell each bag for $0.15 more than he paid; Then the amount he should charge for each bag is:

=$0.5 + $0.15

=$0.65
