<u>Answer:</u>

1

<u>Step-by-step explanation:</u>

3^-1 times (4 times 6) times 2^-3 can be written as:

3^{-1} . (4 × 6) . 2^{-3}

Now we can change the negative powers into positive powers by taking a reciprocal of that term to get:

\frac{1}{3} .  (4 × 6) . \frac{1}{2^{3} }

\frac{1}{3} . 24 . \frac{1}{8} = 1

The expression is simplified where the values in the fractions get cancelled by each other to give 1.

7) The answer is  -124q + 216

Step-by-step explanation:

1. Always Distributive Property first

6) -14 (8 - 15p)           7) -12 ( -18 + 10q)

    -112 +210p                 216 -120q

2. Combine like terms

6) -112  +  7  = -105   your full answer is 210p -105

7) -120q +   -4q  =  -124q  Your full answer is -124q +216.

Hope this helps.

Y is inversely proportional to x. When y=25, x=4 Work out y when x=20
ipn [44]

Answer:

y=5 when x=20

Step-by-step explanation:

Using the format for inverse proportions: y=k/x

To find k, substitute 25 in for y and 4 for x to find:

25=k/4 ⇒ k=100

Using this we can substitute k and x in for 100 and 20 to find:

y=100/20 ⇒ y=5
