Olin [163]

Just do 8 1/3 divided by 5/9 or

25/3 / 5/9

25/3 * 9/5 = 5/1 * 3/1 = 15

So 15 tacos

* = times

Answer:

PC = 14.42 cm

Step-by-step explanation:

If a tangent and secant are drawn from a point outside a circle, then the product of the lengths of the segments of the secant is equal to the square of the length of the tangent.

PC² = PB × BD

PC² = 4 × 52

PC² = 208

PC = $\sqrt{208}$

PC = 14.42 cm

Please answer this with the steps included please y-10 = -5/4x + 30/4 for middle school

Phantasy [73]

y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.

We could put this equation into one of several forms.

Suppose we wanted to put it into slope-intercept form. Then y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x. Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).

If this isn't quite what you wanted, then please share the instructions.
