Step-by-step explanation:

- 5x + 4 > 9 ( subtract 4 from both sides )

- 5x > 5

Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.

x < - 1

Answer:

The northern position would be positive while the southern position would be negative.

Step-by-step explanation:

Imagine 0 as the truck stop. North would be above the truck stop, while south would be below it.

On a number line, anything above 0 is a positive number. Anything below 0 is a negative number.

Therefore, the northern position would be positive while the southern position would be negative.

Answer:

Step-by-step explanation:

∠B and ∠D are same side interior angles and are supplementary angles ( they add up to 180°) because AB ║CD are cut by transversal BD

5x +4x = 180

9x =180

x= 20

∠B = 5*20 =100°

∠D =4*20 =80°

Answer:

2.) B. 14

3.) C. 36 x 10 (to the 6th power)

Step-by-step explanation:

In number 2, when it comes to exponents like that, you're supposed to multiply em, nd when u do that, u get 12. It said find the sum, so u add 12 nd 2 nd get 14.

In number 3, u basically gotta find the area nd that's jus multiplyin 6 x 10 (to the 3rd power) by itself, nd that's the answer u get.

Also, since I really tried, I would really appreciate it if u marked me as brainliest.

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.

Answer:

x = 58º

Step-by-step explanation:

the sum of angles on the same side equals 180º so...

122º+x = 180º        subtract 122º from both sides

x = 58º

Answer:

the answer is 20 and 5

Step-by-step explanation:

Number of hats is 5 and the number of sweatshirts is 20

The total number of items bought is 25

The total amount is $172.50

Let a represent the number of sweatshirts

Number of hats is 25-a

Cost of sweatshirt= 8x

Cost of hat= 2.50×(25-x)

= 62.50-2.5x

8x + 62.50 - 2.5x-172.50

8x-2.5x+62.50-172.50

5.5x -110

5.5x= 110

x= 110/5.5

= 20

Number of hats= 25-20, = 5

Number of sweatshirts= 20

I am pretty sure the answer is 45%

Answer:

$56 x ( 7% + 20% ) = $15.12 => $56 + $ 15.12 = $71.12

Step-by-step explanation:

length of rectangle = ( 4n-5 )

breadth of rectangle = ( 3n-2)

Area and perimeter of rectangle.

by the question ,

We know the area of rectangle = length × breadth

Area = (4n -5) (3n-2)

[tex] = {12n}^{2} - 8n - 15n + 10[/tex]

[tex] = {12n}^{2} - 23n + 10[/tex]

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)

= 14n -14
