P = premium rides g = gold star ride 12p + 8g = 96 p = 3 + g now sub 3 + g in for p in the 1st equation 12(3 + g) + 8g = 96 -- distribute the 12 through the parenthesis 36 + 12g + 8g = 96 -- combine like terms 36 + 20g = 96 -- subtract 36 from both sides 20g = 96 - 36 20g = 60 -- divide both sides by 20 g = 3 now sub 3 in for g in the 2nd equation p = 3 + g p = 3 + 3 p = 6 Lets check it... 12p + 8g = 96 12(6) + 8(3) =96 72 + 24 = 96 96 = 96 (correct) She rides 3 gold star rides at $8 per ride...3 x 8 = $24 <--answer 2. Each child costs $4 and each adult cost $9. 3 adults would cost (3 x 9) = $27 4 children would cost (4 x 4) = $16 Total cost would be (27 + 16) = $43 <--answer

If f(3)=2x^3 -2 , what is the value of f(2)
iris [78.8K]

I'm not sure about this but will give it a try:

Let f(n) = 2xⁿ - 2

Then f(3) = 2x³ - 2

So, f(2) = 2x² - 2

There is a formula for the area of a parallelogram which is bxh
(base x height)

Remember the height is always straight so do not use the 12 value.

It was reported in your department meeting that over the past year your hospital decreased the number of employees by four perce
Tju [1.3M]

Answer:

Number of people employed this year = 373

Step-by-step explanation:

Let the number of employees this year = x

These employees were decreased by 4% then the remaining number of employees this year = x - (4% of x)

= x - 0.04x

= 0.96x

If last year number of people employed were 389 then the number of people employed this year = 0.96×389

= 373.44

When rounded to whole number, number of people employed this year = 373.

How can you find this distance (-3,7),(0,4) in words
Bezzdna [24]

Answer:

The distance between these two given points is:

3\sqrt{2}

Step-by-step explanation:

We are given two points:

(-3,7),(0,4)

<em>The distance between two points (a,b) and (c,d) is given by the distance formula as:</em>

<em>\sqrt{(c-a)^2+(d-b)^2</em>

similarly we can find the length of a line segment by considering the distance between the end points of the line segment.

So here (a,b)=(-3,7)

and (c,d)=(0,4).

Hence distance between these two points is given by:

\sqrt{(0-(-3))^2+(4-7)^2}=\sqrt{(3)^2+(-3)^2}=\sqrt{9+9}\\   \\=\sqrt{18} \\\\=3\sqrt{2}
