Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
You would divide the diameter in half to get the radius which is 4. And do the formula which is a=pie(r) squared. So the answer would be 50.24
Answer:
25.4
Step-by-step explanation:
If double of the number 'x' is 50.8, (2x=50.8)
Then the original number must be half of that value, (x=50.8/2)
50.8/2 = 25.4
Answer:
Samantha would have to watch 4 Movies so x=4

Answer:
3 1/3
Step-by-step explanation:
Make the fractions into improper fractions:
2 1/2 = 5/2
1 1/3 = 4/3
5/2 × 4/3 =
5×4/2×3 =
20/6 =
10/3 =
3 1/3
