Answer: it’s b
Step-by-step explanation:
Hi,
We know that:
a² -- b² = (a -- b)(a + b).
With a = x, and b = 4, we have:
x² -- 16 = x² -- 4² = (x -- 4)(x + 4).
As simple as that. Have you understood ?
Green eyes.
<span>194 = 1/2x + 2(x - 8)
194 = 1/2x + 2x - 16 = 5/2x - 16
5/2x = 194 + 16 = 210
5x = 210 x 2 = 420
x = 420/5 = 84
Therefore, the regular price of a child's ticket is $84 - $8 = $76.
