Answer:

n + 6 = 40

n = 34

Step-by-step explanation:

Sum of a number and 6. That means you got to add n and 6.

'is' means you need to put an equal sign.

n + 6 = 40

Now, lets find what n is.

Isolate the variable by subtracting 6 from both sides.

n = 34

-2(11-12x)= -4(1-6x)

GalinKa [24]

The given equation -2(11 - 12x) = -4(1 - 6x) has infinite solutions

<u><em>Solution:</em></u>

Given that we have to solve the given expression

Given expression is:

-2(11 - 12x) = -4(1- 6x)

We have to use distributive property to solve the given expression

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

Which means,

a(b + c) = ab + ac

Apply this in given expression

-2(11 - 12x) = -4(1-6x)

-22 + 24x = -4 + 24x

When both sides of the equation are simplified, the coefficients are the same, then infinite number of solutions occur

If we end up with the same term on both sides of the equal sign, such as 24x = 24x, then we have infinite solutions

4. Find the monthly average for each list of year-end utility costs given:

BigorU [14]

Answer:

1486.67 or 1487.

Step-by-step explanation:

Find the average of those three things. Add 2,340 plus 470 plus 1650. You get 4460. Since you have three costs, divided 4460 by 3, which is 1486.6 repeating. Round to the nearest hundredth which is 1486.67. Hope this helps!

The functions r and s are defined as follows.

irina1246 [14]

Answer:

r(s(-2)) = -2

Step-by-step explanation:

We are given these following functions:

$r(x) = -2x + 2$

$s(x) = x^2 - 2$

Find the value of r(s (-2)).

First we find the composition of r and s functions. It is:

$r(s(x)) = r(x^2-2) = -2(x^2-2) + 2 = -2x^2 + 6$

At x = -2

$r(s(-2)) = -2(-2)^2 + 6 = -8 + 6 = -2$

r(s(-2)) = -2
