Answer:

1 1/12

Step-by-step explanation:

1 and 6 over 9/2 in converted into an improper fraction before you can do anything. you can do this by multiplying the one by 9 it should be coolant to 9 and then add it to the numerator. the fraction should equal 15/9. once you've got this new fraction you have to find the GCF otherwise known as the greatest common factor . 8 + 9 really don't have a lot of numbers that factor into each other . So in order to convert them to a place where you can easily subtract, you would multiply 22/8 by 9 and you would multiply 15/9 by 8 . this should be equal to 198/72 and 120/72. from this point you can easily subtract and see that the answer would be 78 / 72 . because 78 and 72 both end in 8 and 2 which are even numbers, you can reduce the fraction and convert it to a mixed number. At this point it should be equivalent to 1 1/12

Write an inequality representing the fact that the total perimeter of the garden is at most 40 ft

dlinn [17]

Answer:

Part A) $x+y\leq 20$

Part B) The solution in the attached figure

Step-by-step explanation:

The complete question is

Suppose Rick has 40 ft of fencing with which he can build a rectangular garden. Let X represent the length of the garden and let Y represent the width.

A. Please write an inequality representing the fact that the total perimeter of the garden is at most 40 ft.

B. Please sketch part of the solution set for this inequality that represents all possible values for the length and width of the garden.

Part A)

Let

x ----> the length of the rectangular garden

y ----> the width of the rectangular garden

we know that

The perimeter of the rectangular garden is equal to

$P=2x+2y$

In this problem the word "at most" means "less than or equal to"

The inequality that represent this situation is

$2x+2y\leq 40$

Simplify

$x+y\leq 20$

Part B) we have

$x+y\leq 20$

Isolate the variable y

subtract x both sides

$y\leq -x+20$

The solution of the inequality is the shaded area below the solid line $y= -x+20$

The slope of the solid line is negative (m=-1)

The y-intercept of the solid line is (0,20)

The x-intercept of the solid line is (20,0)

therefore

The solution is the triangular shaded area

see the attached figure

Remember that

Both the length and the width must be positive

Solve for x:(2 x + 3)/3 - 1 = 10
Put each term in (2 x + 3)/3 - 1 over the common denominator 3: (2 x + 3)/3 - 1 = (2 x + 3)/3 - (3)/3:(2 x + 3)/3 - (3)/3 = 10
(2 x + 3)/3 - (3)/3 = ((2 x + 3) - 3)/3:(-3 + 3 + 2 x)/3 = 10
Add like terms. 3 - 3 = 0:(2 x)/3 = 10
Multiply both sides of (2 x)/3 = 10 by 3/2:(3×2 x)/(2×3) = (3×10)/2
(3×10)/2 = (3×10)/2:(3×2 x)/(2×3) = (3×10)/2
(3×2 x)/(2×3) = (2×3)/(2×3)×x = x:x = (3×10)/2
10/2 = (2×5)/2 = 5:x = 3×5
3×5 = 15:Answer: x = 15

Solve the following inequality. Show your work. 2m + 6 > 7(m – 2)

otez555 [7]

Answer:

m < 4

Step-by-step explanation:

Given

2m + 6 > 7(m - 2) ← distribute

2m + 6 > 7m - 14 ( subtract 2m from both sides )

6 > 5m - 14 ( add 14 to both sides )

20 > 5m ( divide both sides by 5 )

4 > m , thus

m < 4

-5x + 32 = 47 What is the answer to the equation

SOVA2 [1]

Answer:

x = -3

Step-by-step explanation:

-5x + 32 = 47

-5x + 32 - 32 = 47 - 32

-5x = 15

-5x / -5 = 15 / -5

x = -3
