Answer:
75=2x-13
75+13=2x-13+13
88=2x
88÷2=2x÷2
44=x
Step-by-step explanation:
The answer is 5.55 repeated because you just divide 50 by 9
Answer:
w = 0
Step-by-step explanation:
Answer:
-sqrt(5) ≤ x ≤ sqrt(5)
Step-by-step explanation:
x^2-5≤0
Add 5 to each side
x^2-5+5≤0+5
x^2 ≤5
Take the square root of each side, remembering to flip the inequality for the negative sign. Since this is less than we use and in between
sqrt(x^2) ≤ sqrt(5) and sqrt(x^2) ≥ -sqrt(5)
x ≤ sqrt(5) and x ≥- sqrt(5)
-sqrt(5) ≤ x ≤ sqrt(5)
