What is the value of m in the equation 3+4m=15−2m

1 answer:

5 0

Greetings!

"What is the value of m in the equation: $3+4m=15-2m$ ?"...

Solve using the properties of equality:
Add 2m to both sides.
 $(3+4m)+2m=(15-2m)+2m$
Add -3 to both sides.
 $((3+4m)+2m)+(-3)=((15-2m)+2m)+(-3)$
Simplify.
 $6m=12$
Divide both sides by 6.
 $(6m)/6=(12)/6$
Simplify.
 $m=12/6$
$m=2$

Hope this helps.

Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) =

KatRina [158]

The equations that can be used to find the lengths of the legs of the triangle are as follows:

100 = (x + 2)² + x²
24 = 0.5 × (x + 2)(x)
x² + 2x - 48 = 0

<h3>How to find the equation of a right triangle?</h3>

The equation that can be used to find the length of the leg of the right triangle uses Pythagoras theorem,

Therefore,

c² = a² + b²

where

c = hypotenuse side
a and b are the other legs

Therefore,

10² = (x + 2)² + x²

100 = (x + 2)² + x²

Therefore, using the area of a triangle,

area of a triangle = 1 / 2 bh

where

b = base
h = height

Therefore,

area of the triangle = 1 / 2 × (x + 2)(x)

24 = 0.5 × (x + 2)(x)

24 = x² + 2x / 2

cross multiply

48 = x² + 2x

x² + 2x - 48 = 0

Translate and solve: fifty times n is at most 500. Give your answer in interval notation.

andrey2020 [161]

Answer: (-infinity,10]

Step-by-step explanation: 50n is less than or equal to 500. So, treat the less than or equal to sign as an equal sign. Then do like regular and divide 500 by 50 to get ten on the right while N stays on the left. To get n is greater than or equal to 10!

WILL GIVE BRANILEST

Luden [163]

Answer: hope this helps love.

Step-by-step explanation:

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

Y= 3x-1 2x+6=y substitution method

vfiekz [6]

Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

Elimination
Substitution
Graphing

Since the question has specific requirements, we are going to use substitution to solve the equations.

Solve:

Given equations

y = 3x - 1

2x + 6 = y

Substitute the y value since both equations has isolated [y]

2x + 6 = 3x - 1

Add 1 on both sides

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

Subtract 2x on both sides

2x + 7 - 2x = 3x - 2x

$\boxed{x=7}$

Find the value of y

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

$\boxed{y=20}$

Hope this helps!! :)

Question 13 helllppp pllllz alomost done

zhannawk [14.2K]

I would think 5 mins because, when you do 33-15 you get 18, and so it drained 18
cm in 6 mins so, that’s 3 cm per min. So if you do 15/3 you get 5 mins. Hope this is helpful! Sorry if it’s wrong :((
