Answer:

Number n increased by 18 = n +18

Number is 2 less than 5 times n= 5n -2

They are same => n +18 = 5n -2

Option B

[ n + 18 = 5n -2

18 +2 =5n - n

20 = 4n

n = 5

Lets check 5+18 = 5*5 - 2

Answer: The total money invested in the field will be $1,623.80

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

p=2(x+y)

p(4.80)=1,584

p=330m

we know that

The perimeter of the field is equal to

330=2(x+y)----> equation A

x=4y-10 ------> equation B

substitute equation B in equation A and solve for y

330=2(4y-10+y)

165=(5y-10)

5y=165+10

y+35

Find the value of x

x=4(35)-10+130

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

A=xy

substitute

A=(130)(35)=4,550m2

step 3

Find the number of bags of seed

Divide the area by 460

4,550/460=9.89 bags

Round up to the nearest whole number

9.89 bags=10 bags

step 4

Find the cost of the seed

(10 )(3.98)=$19.8

step 5

Find the total money invested in the field

1,584+$39.8=$1,623.80

The table below shows the number of hours some business people in two states spend in meetings each week: State A 21 23 24 22 24

Lera25 [3.4K]

State A:
21,22,22,23,23,23,24,24,25

minimum = 21
Q1 = 22
Q2(median) = 23
Q3 = 24
maximum = 25
IQR = Q3 - Q1 = 24 - 22 = 2

state B:
20,20,21,22,23,23,24,46,50
minimum = 20
Q1 = (20 + 21)/2 = 20.5
Q2(median) = 23
Q3 = (24 + 46)/2 = 35
maximum = 50
IQR = 35 - 20.5 = 14.5

I do not believe they are symmetrical....I think state B is skewed to the right

HELP FASSTT THANK U IF SO

valentina_108 [34]

Answer:

The answer is -13/8 or -1 5/8 in mixed form.

Step-by-step explanation:

The fraction 1 5/8 converted to improper is 13/8 so count 13 points to the right of the number line from 0. So that is where it falls.

Now if we are to find the opposite of a positive integer or fraction we are just to put a negative mark so it will be -1 5/8 or -13/8 in improper form. So just count 13 points to the left of the number line from 0 and that's your answer buddy!

But tbh this is actually an extensive and time taking process but if you follow this you can be sure of your answer. So the easier process is to see the whole and the parts of whole. As you can see there are 8 parts between each number so it means each number is divided into 8 parts and to make it easier the fraction shows that 1 5/8 has 8 parts for each to. So we will take the 1 of the 1 5/8 and skip 8 parts to the whole number 1. Then we will take the 5 from 5/8 and count 5 points from 1. That's the position of 1 5/8 on the number line. As for the opposite, add negativity sign and do just the same! And that's the answer!

HOPE it helps though...
