Answer:

D.) 4 1/20

Step-by-step explanation:

2 1/4 * 9/5

Change 2 1/4 to an improper fraction

4*2+1 = 9/4

9/4 * 9/5

Multiply straight across the numerators and then straight across the denominators

9 * 9 = 81   4 * 5 = 20

81/20

Change this back into a mixed number

81 divided by 20 = 4 1/20

Answer:

D. 0.343

Step-by-step explanation:

You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.

This strategy also can be applied to the number 0.3409 but in this occasion the result is different:

0.343 - 0.3409 = 2.1\times 10^{-3}

That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .

Can someone help me with this question? I seem to be getting a negative answer every time :(
NeX [460]

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 =
