Make t the subject of the formula: S = at + bt

To make t the subject is basically isolating t

S = at + bt
We see on the right side that t is common, so we factor it out.

S = t(a + b)
Divide by (a+b) to isolate t

$\frac{S}{a + b} = \frac{t(a+b)}{(a+b)}$
a + b and a + b cancels out
We are left with the answer:
t = $\frac{S}{a+b}$

$S = at + bt \\
t(a+b)=S\\
t=\dfrac{S}{a+b}$

The percentages of voters classed as Liberals in three different election districts are divided as follows: in the first distric

ASHA 777 [7]

Answer:

47%

Step-by-step explanation:

Chance of liberal in first district = 21%

Chance of liberal in second district = 45%

Chance of liberal in third district = 75%

Assuming that all districts are equally likely to be selected, the probability that a randomly selected voter is a liberal is given by the average of the probability of a voter being a liberal in each district:

$P = \frac{0.21+0.45+0.75}{3}= 47\%$

The probability that she will be a Liberal is 47%.

Divide and simplify.

vredina [299]

Answer:

$\frac{ {x}^{2} + 10x + 16 }{ {x } {}^{2} + 6x + 8} \div \frac{1}{x + 2}$

$\frac{ {x}^{2} + 8 x+ 2x + 16}{ {x}^{2} + 4x + 2x + 8} \times (x + 2)$

$\frac{x(x + 8) + 2 (x + 8)}{x(x + 4) + 2(x + 4)} \times (x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 2)(x + 4)} \times ( x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 4)}$

slamgirl [31]

Answer:

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

So the zeros of <span>f<span>(x)</span></span> are precisely the values of x which make at least one of the linear factors 0, namely: 6, <span>−5</span> or 9.
