The irrational number is 12.
Have a brainly day!
It is -7.83 because you distribute the -6 to the n and the 1 inside the parentheses which makes you get -6n-5=42. Since 5 is negative you add it to -5 and the 42 on the other side of the equation which turns out to -6n=47. You then divide -6 on both sides of the equation. -6n divided by -6 cancels out so 47 divided by -6 equals -7.83333333 which rounds to -7.8
Answer:
A
x = 67
Step-by-step explanation:
the number is being reduced by 23 which means x-23 = 44 and x = 44+23 =67
Answer:
x = 25
Step-by-step explanation:
The angles in a triangle add up to 180°, so we can write an equation to model the situation:
55 + 75 + 2x = 180
Now, we can simplify and solve:
130 + 2x = 180
2x = 50
x = 25
