Yes because the circumference is also proportional to the radius of the circle, and the constant of proportionality is because the diameter is twice as long as the radius.
Answer:
The question is kinda incorrect but if it is.... The answer should be 1
Step-by-step explanation:
Original :1.5 + 1
New: 2.5
I assume the equation is
√(2x - 5) - √(x + 6) = 0
Note the domains for the root expressions:
• √(2x - 5) : 2x - 5 ≥ 0 ⇒ x ≥ 5/2
• √(x + 6) : x + 6 ≥ 0 ⇒ x ≥ -6
So any valid solution we find must be at least 5/2.
Move one term to the other side.
√(2x - 5) = √(x + 6)
Take squares.
(√(2x - 5))² = (√(x + 6))²
2x - 5 = x + 6
Solve for x :
x = 11
Sally is 10 years old. <span>Her mother is five times older. </span>If this is put into an equation: x = (age of sally)(5)
x = (10)(5)
x = 50 years
Sally's mom is 50 years old.
