Answer:

x =14

Step-by-step explanation:

-1/2 x+1 = -x+8

Add x to each side

-1/2 x +x+1 = -x+x+8

1/2x +1 = 8

Subtract 1 from each side

1/2x +1-1- =8-1

1/2x = 7

Multiply each side by 2

1/2x *2 =7*2

x =14

Number of ones = 60
Number of twos = 62
Number of threes = 59
Number of fours = 64
Number of fives = 63
Number of sixes = 75

Total even outcomes = total number of two, four and sixes = 62 + 64 + 75 = 201

Total outcomes = 60+62+59+64+63+75= 383

Probability if rolling an even number = 201/383

percentage= 201/383 × 100 = 52.48% ~ 52.5%

There is no solution  for the first one

if you eliminate y   you get 2 equations
-13x - 13z = -25
-13x - 13x = -15    

- there is no solution to theses

a23  means the element in the second  row and the 3rd column

so its -5

ANSWER RIGHT NOW FOR BRAINLIST!!!
MrMuchimi
The perimeter is 4/3x(3), or 12/3x.
The area is (2x+2)^2
Therefore, we must solve the equation
4x^2+4x+1= 0
This eventually factors to x = -0.5.
