(10+t)/(18+t)=8/10
8(18+t)=10(10+t)
144+8t=100+10t
44=2t
t = 22 throws

Rewrite the expression using Distributive Property, then simplify<br><br> -1(x-9)+4x

pentagon [3]

First ask yourselfhat needs to be dristributed.
That would be -1 (x-9)
To distribute you have to multiply the number out side of the parentheses (-1) by each term inside the parentheses( x and -9)
-1×x=-x
-1×-9=9
Now the expression is
-x+9+4x
To simplify you have to combine like terms (4x and-x)
4x-x=3x
Your answer is 9+3x or 3(3+x).

katovenus [111]

Answer:

$200\ families$

Step-by-step explanation:

To find the sample size, we equate to find 100%.

Let sample size be denoted by $t$

$If\ 12\%=24\\100\%=t\\t=\frac{100\%\times24}{12\%}\\=200$

Hence, the sample has 200 families.
