The sign is flipped, please brainiest me! :)
Answer:
that is a great question i dont know.
explanation: the human brain is in different categories.
1. You can add 7 units to both sides of the scale so it becomes a balance between x on the left and 21 on the right.
x ___ 21
1A) The only number from the set that will keep the balance is x ∈ {21}
1B) The number on the right (21) will be more than x for x ∈ {0, 1, 7, 14}
1C) The number on the right (21) will be less than x for x ∈ {28, 30}
2A) (x +x +x) +(2 +4) = 102
3x +6 = 102 . . . . . . . . simplified equation
2B) Solving the equation, you have
3x = 102 -6
x = 96/3 = 32
The number that could be a value of x is 32.
Answer:
260x = 170
x=170/260 * 100% = 65.4 %
Step-by-step explanation:
Answer:
∠ KLM = 27°
Step-by-step explanation:
∠ KLM + ∠ NLM = 90 , that is
3x + 7x = 90
10x = 90 ( divide both sides by 10 )
x = 9
Thus
∠ KLM = 3x = 3 × 9 = 27°
