Answer:

x= <u>-</u><u>6</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>-</u><u>3</u>

<u> </u><u> </u> 4 or 2

Step-by-step explanation:

1/2=2/4

2/4+1/4+6=-3/4

3/4+x=-3/4

subtract 3/4 on both sides

3/4+x=-3/4

-3/4. -3/4

x=-6/4

simplified x=-3/2

Step-by-step explanation:

1/4 + 1/2 + x = -3/4

1/4 + 2/4 + x = -3/4

3/4 + x = -3/4

-3/4. -3/4

x = - 1 1/2

7. The cost of renting the party room for 10 people is $117.50. The cost of renting the room is $151.25 for 15 people. Write an
Viktor [21]

Answer:

C = 6.75n + 50

Step-by-step explanation:

The equation for the cost of renting the party room can be written in the form;

C= mn+k ......i

Where C = cost

n = number of people

Substituting the 2 cases into the equation we have,

Case 1

117.5 = 10m + k ......1

Case 2

151.25 = 15m + k .....2

Subtracting eqn 1 from 2 we have

151.25 - 117.50 = 15m - 10m

5m = 33.75

m = 33.75/5 = 6.75

Substituting m = 6.75 into eqn 1, we have

117.50 = 10(6.75) + k

k = 117.5 - 67.50

k = 50

Therefore, rewriting the eqn i, we have

C = 6.75n + 50

The table and the graph each show a different relationship between the same two variables, x and y:
Gelneren [198K]

Answer:

110

Step-by-step explanation:

The answer is 110

If the function for the table is y=90x and the function for the graph is y=80x, then at x=11, the table would be at (11, 990) and the graph at (11, 880) meaning that the y value of the table would be 110 more than the y value of the graph.

Lena [83]

Answer:

After adding 8 you get  14 = x/4.

Step-by-step explanation:

6=x/4-8  Add 8 to both sides:

6 + 8 = x/4 - 8 + 8

14 = x/4

x = 4*14

x = 56.
