Answer:

3.44

Step-by-step explanation:

(-6.8 - c) / 1.2 = -2.8

(multiply both sides by 1.2)

-6.8 - c = -3.36

(add 6.8 to both sides)

-c = 3.44

c = 3.44

Can someone help me with this 2 step eqaution

Snowcat [4.5K]

The answer is: " 40 books " .
____________________________________________
Explanation:
____________________________________________
Let "x" equal the number of books that Jill started with. Solve for "x" :
____________________________________________
x – (1/2)x + 16 = 36 ;

1x – (1/2)) = (1/2)x ;

(1/2)x + 16 = 36 ;

Subtract "16" from EACH SIDE of the equation:

(1/2)x + 16 – 16 = 36 – 16 ;

(1/2)x = 20 ;

Multiply each side of the equation by "2" ;

2*(1/2)x = 20 * 2 ;

to get: x = 40 .

Please help me answer thi question

FinnZ [79.3K]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (5, 3 )

m = $\frac{3-3}{5-2}$ = $\frac{0}{3}$ = 0

Can someone pls explain how to do this

Rama09 [41]

The polynomial A is represented as x - 2, making option A the right choice.

In the question, we are asked to find the correct representation of A, when the algebraic expression (x² + x)/(x + 3) can be rewritten as the algebraic expression A + 6/(x + 3), where A is a polynomial.

Thus, we can write an equation,

A + 6/(x + 3) = (x² + x)/(x + 3),

or, A + 6/(x + 3) - 6/(x + 3) = (x² + x)/(x + 3) - 6/(x + 3) {Subtracting 6/(x + 3) from the both sides of the equation}

or, A = (x² + x)/(x + 3) - 6/(x + 3) {Simplifying},

or, A = (x² + x - 6)/(x + 3) {Subtracting the two fractions with the same denominator (x + 3)},

or, A = (x² + 3x - 2x - 6)/(x + 3) {Mid-term factorization},

or, A = {x(x + 3) - 2(x + 3)}/(x + 3) {Taking common},

or, A = {(x - 2)(x + 3)}/(x + 3) {Taking (x + 3) common},

or, A = x - 2 {Cancelling (x + 3) from the numerator and the denominator}.

Thus, the polynomial A is represented as x - 2, making option A the right choice.

What are the excluded values? m+5/mn+3m

In-s [12.5K]

values that are excluded from the domain of a rational expression are values that make the denominator 0, since if that's so, the rational will be undefined. That happens when the denominator is zero out, let's do so

$\bf mn+3m=0\implies m(n+3)=0\implies \begin{cases} m=0\\ n=-3 \end{cases}$

so, if ever m = 0, the denominator will become 0 and the rational becomes undefined, and whenever n = -3, the same will happen to the rational, thus those values are excluded.
