You will end up with 8 bc if you cut it in half it is dividing so you would do 4×2 and the answer is 8
Answer:
148
Step-by-step explanation:
Average = sum of numbers /total numbers
let x = 5th number
123.2 = (118+ 128 + 124,+ 98 + x) / 5
123.2 = (468 + x) / 5
Multiply both sides by 5
616 = 468 + x
x = 148
Answer:
The expression is not equivalent to other three is 9(n-9) .
Option (B) is correct .
Step-by-step explanation:
Take first expression
= -9 -7n + 16n
= 9n-9
Take second expression
= 9(n-9)
= 9 × n - 9 × 9
= 9n - 81
Take third expression
= n-9+8n
= 9n-9
Take fourth expression
= 9n-9
Therefore expression is not equivalent to other three is 9(n-9) .
Option (B) is correct .
Answer:
1. 3
2. 2
3. 2
4. 6
5. No solution
Step-by-step explanation:
2x+3y=8 (1)
-6x+4y=11 (2)
3(1) + (2)
6x + 9y = 24
-6x + 4y = 11
13y = 35
y = 35/13
x = -1/26
3x-y=3 (1)
-2x+2y=6 (2)
2(1) + (2)
6x - 2y = 6
-2x + 2y = 6
4x = 12
x = 3
y = 3(3) - 3 = 6
3x+4y=-10 (1)
5x-2y=18 (2)
(1) + 2(2)
3x + 4y = -10
10x - 4y = 36
13x = 26
x = 2
5x-2y=3 (1)
2x-y=0 (2)
(1) - 2(2)
5x - 2y = 3
-4x + 2y = 0
x = 3
2(3) - y = 0
y = 6
3x+2y=10 (1)
6x+4y=14 (2)
2(1) - (2)
6x + 4y = 20
6x + 4y = 14
0 = 6 is a false statement so no solution
