Answer:

(5,-3)

A spinner has sections labeled W W , X X , Y Y , and Z Z . The faces of a number cube are labeled 1, 2, 3, 4, 5, and 6. What is
Kisachek [45]
Total number of sections on the spinner = 4
So there can be 4 outcomes on 1 spin of the arrow on the arrow.

Number of faces of the cube = 6
So there can be 6 outcomes on rolling of the dice.

For each outcome of the spinner, there can be 6 outcomes of rolling a dice. So for 4 outcomes of the spinner, there will be 6 x 4 = 24 outcomes in total.

For example, WW and either of {1,2,3,4,5,6} can occur. This makes folloiwng 6 outcomes: WW1, WW2, WW3, WW4, WW5 and WW6

Same goes for XX (6 outcomes), YY (6 outcomes) and ZZ (6 outcomes)

Thus in total there will be 24 outcomes. 
So option j gives the correct answer

Given the system of equation 7x-3y = 48 .......Eq 1 2x+ y = 35 ........Eq 2 __________ To solve this system by elimination and m
lesya692 [45]

Answer:

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48    ---- (1)

-

<u>    2x + y = 35   ----</u>-   (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

<u>    14x + 7y = 245      </u>

<u>      0   -13y = -149</u>

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75
