Answer:
a) 25/324
b) 1/4
c) 1/3
Step-by-step explanation:
a) [⅓A + ⅓B]² = (⅓)²[A + B]²
= (1/9) [½ + ⅓]²
= (1/9)(⅚)²
= (1/9)(25/36)
= 25/324
b) ½ × ½ = ¼
c) (½ × ⅓) + (⅓ × ½) = 2 × ⅙ = ⅓
Answer:
Move all terms containing y to the left, all other terms to the right
<u>Add -14y to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 5y + -14y = -9y
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 14y + -14y = 0
</u>
<u></u><u></u>
<u></u>
<u>Add '20' to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: -20 + 20 = 0
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 7 + 20 = 27
</u>
<u></u><u></u>
<u></u>
<u>Divide each side by -9</u>

Answer:
$ 15.00
Step-by-step explanation:
9.95 is JUST about 10
5.25 is close to 5
10 + 5 = 15
64 x 10 = 640
Easier way to simplify :
64 x 1 = 64 and then put the 0 at the end which = 640
