Answer:

n = 5

Step-by-step explanation:

First, you'd want to expand the entire equation to solve it.

4 (2n + 5) = 60

8n + 20 = 60

8n = 40

n = 5

I hope this helped!

Answer:

n = 5

Step-by-step explanation:

4(2n+5)=60

2n+5=15 Divide both sides by 4

2n = 10 Subtract 5 from both sides

n = 5 Simplify and divide by 2 to isolate the variable

Help me I dunno know.

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

The 1st option is not a function because the inputs 9 and 10 have more than one output.

The 2nd option is not a function because the input 3 has more than one output.

The 3rd option is a function because each input only has one output.

The 4th option is not a function because the input 5 has more than one output.

To find the constant of proportionality:

⇒ must define constant of proportionality

⇒ Constant of Proportionality: ratio of two proportional values at a

constant value

⇒ (in this case) two proportional values are x and y

The ratio between x and y is equal to

$\frac{y}{x} =\frac{66}{1.2}=55$

Answer: 55 or Choice 1

Hope that helps!

This is equivalent to:

(2.2533/2.59)(10^8/10^4)

(0.87)(10^4) which is:

0.87X10^4 which is equal to:

0.87X10000 which is equal to:

8.7X1000 and since 1000=10^3 we can say:

8.7X10^3

A ski patrol unit has nine members available for duty, and two of them are to be sent to rescue an injured skier. In how many wa

alexgriva [62]

Answer:

Step-by-step explanation:

The number of two of the nine members of ski patrol unit can be chosen is equal to the combinations of 9 taken 2. This can be calculated using the formula:

$\frac{9!}{2!*(9-2)!}$

= $\frac{9!}{2!*7!}$ , where

9! =9×8×7×6×5×4×3×2×1 and

7!=7×6×5×4×3×2×1

2!=2×1 then the equation becomes:

= $\frac{9*8}{2}$ =36
