**Answer:**

y = (7/8)x + 7

**Step-by-step explanation:**

"7 over 8 x" is incorrect; you meant "(7/8)x" (which is not the same as "7 over 8 x." Thus, your line is y = (7/8)x - 7. The slope of a parallel line is the same, or (7/8). Given that the line passes thru (8,0), we have enuf info with which to calculate the y-intercept. Write out: y = mx + b. Immediately replace m with (7/8), y with 0 and x with 8, obtaining: 0 = (7/8)(8) + b. Then b = 7, and the equation of this new, parallel, line is y = (7/8)x + 7.

Now,

**Answer:**

AE = 15 cm; ED = 18 cm; AD = 15 cm (given)

**Step-by-step explanation:**

ΔBEC ~ ΔAED so ...

AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE

Substituting given numbers (lengths in centimeters), we have ...

15/10 = 1 + 5/BE

1/2 = 5/BE

BE = 10

Similarly, ...

1/2 = 6/CE

CE = 12

Then the unknown sides are ...

**AE =** AB + BE = 5 + 10 = **15 . . . cm**

**ED =** CE + CD = 12 + 6 = **18 . . . cm**

First of all, how many pounds of flour did she use to bake a cake? If it is a fraction, divide the numerator by the denominator to get the decimal form.

e.g. 1/2= .5 ( because 1 divided by 2!)
