D
Step-by-step explanation:
Answer:
total number of fish = 126
Step-by-step explanation:
let n be the total number of fish in the tank , then
n = 18 ( multiply both sides by 7 to clear the fraction )
7 × n = 7 × 18
n = 126
total number of fish in the tank is 126
Answer:
6). Option (B)
7). Option (C)
Step-by-step explanation:
6) Property of a triangle :
"Sum of all interior angles is 180°"
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
5x + 3 = 180°
5x = 177°
x =
(x + 2)° = 37.4°
(2x - 1)° = 69.8°
(2x + 2)° = 72.8°
Option (B) is the answer.
7). (4x + 2)° + (2x + 1)° + (x - 1)° = 180°
7x + 2 = 180°
7x = 178°
x =
(4x + 2)° = 103.7
(2x + 1)° = 51.9°
(x - 1)° = 24.4°
Option (C) will be the answer.
The solution of the given inequality 12x - 3x + 11 > 4x - (17 - 9x) is x < 7
The given inequality is,
12x - 3x +11 > 4x - (17-9x)
Simplify the left-hand side of the inequality by combining like terms.
We can simplify 12x - 3x to get 9x, so our inequality becomes:
9x + 11 > 4x - (17 - 9x)
Next, we can simplify the expression inside the parentheses on the right-hand side of the inequality by distributing the negative sign:
9x + 11 > 4x - 17 + 9x
We can further simplify this by combining like terms on the right-hand side of the inequality:
9x + 11 > 13x - 17
Now, we can isolate the variable on one side of the inequality by subtracting 9x from both sides:
11 > 4x - 4x - 17
Add 17 to both sides to isolate the variable:
28 > 4x
Finally, we can solve for x by dividing both sides by 4:
x < 7
Therefore, the solution to the inequality 12x - 3x + 11 > 4x - (17 - 9x) is x < 7.
