Subtract.
Katena32 [7]
(8x - 8y + 9) - (5x - 8y - z) = 3x + z + 9

8 - 5 = 3
-8 - (-8) = 0
9 - 0 =9
0 - (-z) = z

so it is written 3x +z +9

A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i
Likurg_2 [28]
R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44

Jane has 34 candles leftover from the last craft show and Brianna
katrin [286]

Answer:

4 hours

Step-by-step explanation:

Given that the number of leftover candles for Jane = 34

and  the number of leftover candles for Brianna = 2

Rate of candle making for Jane = 24 candles/ hour

Rate of candle making for Jane = 32 candles/ hour

As they work for h hours to make candles.

So, in h hours, the number of new candles made by Jane = 24h candles

For Jane, the total number of candles after h houres, including the leftover candles = 24h+34 \cdots(i)

Similarly, in h hours, the number of new candles made by Brianna = 32h candles

For Brianna, the total number of candles after h houres, including the leftover candles = 32h+2 \cdots(ii).

As they want to have the same number of candles at their stalls, so equating the numbers of candles from equations (i) and (ii), we have

24h+34=32h+2 \\\\\Rightarrow 32h-24h=34-2 \\\\\Rightarrow 8h=32\\\\

\Rightarrow h=32/8=4 hours.

Hence, both need to work for 4 hours to have the same number of candles.
