Solve the equation.

b + 6 = 27

### Answers

**Answer:**

**Step-by-step explanation:**

b+6=27

b=27-6

b=21

**Answer:**

b = 21

**Step-by-step explanation:**

To find this answer, all you have to do is subtract 6 from both sides of the equal sign, where you will cancel out the 6 and subtract 6 from 27. 27 minus 6 is 21, so you are left with b = 21

Marc is creating a rectangular garden in his back yard. The length of the garden is 18 feet. The perimeter of the garden must be at least 60 feet and no more than 76 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.

### Answers

Answer:[12,20]

Step-by-step explanation:

The **value **of **width **will be from 12 to 20.

What is the perimeter of the rectangle?

The **sum** of all the sides of the **rectangle** will be known as the **perimeter **of the **rectangle**. Let L be the **length** and W be the **width** of the rectangle.

Then the **perimeter** of the **rectangle** will be

Perimeter of the rectangle = 2(L + W) units

Marc is **creating** a **rectangular** garden in his **backyard**. The length of the garden is 18 feet. The **perimeter** of the garden must be at **least** 60 feet and **no more** than 76 feet.

Then the **inequality** is given as,

60 < 2(W + 18) < 76

**Simplify** the inequality, then the **value** of the **width** W will be

60 < 2(W + 18) < 76

30 < (W + 18) < 38

12 < W < 20

Thus, the **value **of the** width **will be from 12 to 20.

1. In part (b) of the example, why isn't AB a correct answer? 2. In part (c) of the example, would KJL be an appropriate answer?

### Answers

**Answer:**

**Step-by-step explanation:**

1. AB isn't a correct answer because it only refers to the part of the line between point A and point B. This is incorrect because it doesn't represent the whole line which goes on infinity past point A (as seen by the arrow).

2. KJL would not be an appropriate answer because the points must be listed in the same order that they appear in direction of the line. The angle shown is angle K so K should be the middle letter as it is the middle point with the angle. KJL would not be appropriate because it would refer to the angle J if there was another line between J and L.

Is the answer

**Answer:**

38.9 degrees C

**Step-by-step explanation:**

Use the equation:

[tex]C=\frac{5}{9} (F-32)[/tex]

to convert degrees Fahrenheit to degrees Celsius. So replace the value for the Fahrenheit with 102 and solve for C:

[tex]C=\frac{5}{9} (F-32)\\C=\frac{5}{9} (102-32)\\C=\frac{5}{9} (70)\\C=\frac{350}{9} \approx38.89\,^oC[/tex]

what’s the slope-intercept form of y + 3 = 4(x - 5),

### Answers

Slope-intercept form is: y = mx + b

m = slope

b = y-intercept

y + 3 = 4(x - 5)

Distribute the 4

y + 3 = 4x - 20

Subtract 3 from both sides.

y = 4x - 23

**Answer:**

**Step-by-step explanation:**

Slope intercept form...

y=mx+c

where, m=slope

c=intercept

y + 3 = 4(x - 5)

Open the Brackets.

y + 3 = 4x - 20

SUBTRACT **3** FROM BOTH SIDES.

y + 3 (-3)= 4x - 20 (-3)

Take note of the signs and solve.

y = 4x - 23

4 is the slope.

-23 is the intercept.

A bonus of £2100 is shared by 10 people who work for a company. 40 percent of the bonus is shared equally between 3 managers. The rest of the bonus is shared equally between 7 salesmen. One of the salesmen say if the bonus is shared equally between all 10 people I will get 25 percent more money. Is the salesmen correct? you must show your answer.

Help me on this question and please show your working out and explain thank you

### Answers

**Answer:**

Salesman is not correct

**Step-by-step explanation:**

First we calculate the share of salesman when 60 percent of bonus is shared among 7 salesmen:

**Bonus Share For 7 Salesmen = (0.6)(£ 2100)**

**Bonus Share For 7 Salesmen = £ 1260**

Now, this is equally divided among 7 salesmen:

**Bonus Share of 1 Salesmen (when 60% is shared) = S₁ = £ 1260/7**

**S₁ = £ 180**

Now, we calculate the share each salesmen get if bonus is equally divided among 10 people:

**Bonus Share of 1 Salesmen (when equally shared) = S₂ = £ 2100/10**

**S₂ = £ 210**

**S₂/S₁ = £ 210/£ 180**

**S₂/S₁ = 1.16**

**S₂ = 1.16S₁**

**S₂ = 116% of S₁**

This means that if bonus is equally divided between all 10 people then the salesman will get 16 percent more money.

**Therefore, salesman is not correct**
