96 divided by 6 in distributive property

Inga [223]

Distributive property of division: (a + b) : c = a : c + b : c

96 : 6 = (90 + 6) : 6 = 90 : 6 + 6 : 6 = (60 + 30) : 6 + 1
= 60 : 6 + 30 : 6 + 1 = 10 + 5 + 1 = 16

For the final days before the election, the campaign manager has a total of $41,500 to spend on TV and radio campaign advertisem

Margaret [11]

Answer: There are 9 T.V. and 29 radio ads.

Step-by-step explanation:

Since we have given that

Total amount spend on TV and radio = $41,500

Total number of voters using the allocated funds = 148,000

Let the number of TV be 'x'.

Let the number of radio ads be 'y'.

Cost of each TV = $3000

Cost of each radio ads = $500

Number of voters see T.V. = 10,000

Number of voters use radio = 2000

So, According to question, it becomes,

$3000x+500y=\$41500\implies\ 30x+5y=415\\\\10000x+2000y=148000\implies 10x+2y=148$

Using the graphing method, we get that

These two lines are intersect at (9,29).

Hence, there are 9 T.V. and 29 radio ads.

Find the slope of this line: (15,7) (3,-2)<br><br> Help

Oliga [24]

Answer:

$m=\frac{3}{4}$

Step-by-step explanation:

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(15,\:7\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)$

$m=\frac{-2-7}{3-15}$

$\mathrm{Refine}$

$m=\frac{3}{4}$
