Answer:

-1/3

Step-by-step explanation:

It is -1/3 because your going down and its like going underground and the grass is the 0-line then anything lower is a -x number if you were going up the "slope" then it would be a positive number.

The model represents the equation <br> 4x+ 4 = 12<br> What value of x makes the equation true
myrzilka [38]

Answer:

B

Step-by-step explanation:

All you have to basically do on this one is go backwards.

The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).

12-4=8

Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.

8/4=2

Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12

Hope this helped!

Can you help me with my homework please
umka21 [38]

#4(a)

row-seat: 3- 13, 4-15, 5-17, 6-19, 7-21

(b)

the equation works for row 1 but not for any of the rows after this

Ex: Row 2, S=7(2)+2, this would equal 14 but there isn't 14 seats in row #2

(c)

S=2(1)+7, there is 9 seats in row 1

2(2)+7=11,  there is 11 seats in row 2

2(3)+7= 13, there is 13 seats in row 3

(d)

2(15)+7=37

2*15=30, 30+7=37

(e)

91=2(r)+7

91-7=2(r)+7-7

84=2(r)

84/2=2(r)/2

42=r, the row with 91 seats is row 42

What is 250/363 in its simplest form
zaharov [31]
You find the GCF of 250 and 363 by factoring. 250 = 5^4 * 2. 363 = 3 * 11^2, and they have no common factors, so 250/363 is already in its simplest form!

In the data set below, what is the range? 9, 4, 9, 2, 8, 2, 1
noname [10]
First put these in order from least to greatest.

1,2,2,4,8,9,9 is the correct order
Range is when we subtract the greatest value of our data set from the smallest so in our case it would be 9-1 which leaves us with our answer that 8 is your range.

a father and his son clean the house together in 2 hours. when the son works alone, it takes him an hour longer to clean than it
Marizza181 [45]
It takes the son one and half hours to clean the house. To find this you need the equations F+S=2 and F+1=S. (F=father and S=son) You take the F+1 and substitute it in for S in F+S to get F+(F+1)=2. Then you combined like factors, 2F+1=2, and simplify to get F=.5hr. After this you plug .5 in to F+1=S to get (.5)+1=S, meaning it takes the son 1.5 hour to clean the house.
