Answer:

m=3

Step-by-step explanation:

Simplifying

18 = 5m + 3

Reorder the terms:

18 = 3 + 5m

Solving

18 = 3 + 5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-5m' to each side of the equation.

18 + -5m = 3 + 5m + -5m

Combine like terms: 5m + -5m = 0

18 + -5m = 3 + 0

18 + -5m = 3

Add '-18' to each side of the equation.

18 + -18 + -5m = 3 + -18

Combine like terms: 18 + -18 = 0

0 + -5m = 3 + -18

-5m = 3 + -18

Combine like terms: 3 + -18 = -15

-5m = -15

Divide each side by '-5'.

m = 3

Simplifying

m = 3

hope this helps

A wire is (7x – 3) meters long. A length of (3x – 4) meters is cut for use(a) How much wire is left?
ipn [44]

Answer:

The amount of wire left is 4x + 1

Step-by-step explanation:

Initially, the wire is (7x - 3) meters long.

A length of (3x - 4) meters is cut.

How much wire is left?

Initial amount subtracted by the amount that is cut. So

(7x - 3) - (3x - 4) = 7x - 3 - 3x + 4

We combine the like terms

7x - 3x - 3 + 4 = 4x + 1

The amount of wire left is 4x + 1

There are 26 third graders and 32 fourth graders going on a field trip. Each van can carry 10 students. How many cans are needed
iragen [17]

Answer:

26+32=10v

add numbers

58=10v

10v=58

divide both sides by 10

v=5.8

There will be 6 vans needed

58/6=9.6

There will be 10 students in four vans, and 9 students in two vans.

A hiker begins a trip by first walking 22.2 km
Dominik [7]

9514 1404 393

Answer:

  20.6 km

Step-by-step explanation:

Using (East, North) coordinates, the hiker's position ends up being ...

  22.2(cos(-45°), sin(-45°)) +40.1(cos(65°), sin(65°))

We're only interested in the second coordinate of this total, which is ...

  22.2sin(-45°) +40.1sin(65°) ≈ -15.698 +36.343 = 20.645 . . . km

The y-component of the hiker's position at the end of the second day is 20.6 km north of her starting location.

Determine the equations of the vertical and horizontal asymptotes, if any, for g(x)=x-2/x^2+4x+3
KatRina [158]

Answer:

<h2>B. x = -1, x = -3, y = 0</h2>

Step-by-step explanation:

g(x)=\dfrac{x-2}{x^2+4x+3}\\\\vertical\ asymptote:\\\\x^2+4x+3=0\\x^2+x+3x+3=0\\x(x+1)+3(x+1)=0\\(x+1)(x+3)=0\iff x+1=0\ \vee\ x+3=0\\\\\boxed{x=-1\ \vee\ x=-3}\\\\horizontal\ asymptote:\\\\\lim\limits_{x\to\pm\infty}\dfrac{x-2}{x^2+4x+3}=\lim\limits_{x\to\pm\infty}\dfrac{x^2\left(\frac{1}{x}-\frac{2}{x^2}\right)}{x^2\left(1+\frac{4}{x}+\frac{3}{x^2}\right)}=\lim\limits_{x\to\pm\infty}\dfrac{\frac{1}{x}-\frac{2}{x^2}}{1+\frac{4}{x}+\frac{3}{x^2}}=\dfrac{0}{1}=0\\\\\boxed{y=0}
