Answer: 84
Step-by-step explanation: 7 Times 12 because each foot is 12 inches
-12x - 9 = -6y
-12x + 6y -9 = 0
-12x + 6y = 9 is the answer
Since they decided to be extremely ridiculous and deleted my answer for "not showing enough work", here I am again:
Since it says that Kiwi is 13 less than TWICE Granny's age, I divided 77 (Granny's age) by 2, which gave me 38.5

I had originally said "20 or 20 and a half years old" because depending on your format of testing/worksheet, you may not have the option of putting halves.
Answer:
3.5 units
Step-by-step explanation:
Because ΔPQT is 45-45-90, QT = PQ√2. Therefore, <em>QT is 2</em>.
<em>RS is also 2</em> because all sides of a square are congruent.
Knowing this, we can use the pythagorean theorem to find SU.
<em>RS² + SU² = RU² -> 2² + SU² = 4² -> 4 + SU² = 16 -> SU² = 12</em>
So, SU = √12 ≈ 3.5 units
The answer to this question is d
