Answer:

Hello,~There

Solve 6x – 4x – 3 = 11 for x.

Simplifying

x = 7

Step-by-step explanation:

Simplifying

6x + -4x + -3 = 11

Reorder the terms:

-3 + 6x + -4x = 11

Combine like terms: 6x + -4x = 2x

-3 + 2x = 11

Solving

-3 + 2x = 11

Solving for variable 'x'.

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

Add '3' to each side of the equation.

-3 + 3 + 2x = 11 + 3

Combine like terms: -3 + 3 = 0

0 + 2x = 11 + 3

2x = 11 + 3

Combine like terms: 11 + 3 = 14

2x = 14

Divide each side by '2'.

Answer:

x=7

Step-by-step explanation:

Let's solve your equation step-by-step.

6x−4x−3=11

Step 1: Simplify both sides of the equation.

6x−4x−3=11

6x+−4x+−3=11

(6x+−4x)+(−3)=11(Combine Like Terms)

2x+−3=11

2x−3=11

Step 2: Add 3 to both sides.

2x−3+3=11+3

2x=14

Step 3: Divide both sides by 2.

2x

2

=

14

2

x=7

Given the system of equations presented here:
Bumek [7]

ANSWER

The correct answer is option B

EXPLANATION


The equations are

3x+5y=29---(1)


and


x+4y=16---(2)


When we multiply the second equation by -3, we obtain;


-3x-12y=-48---(3)


When we combine this new equation with equation (1).


-7y=-19


We can see that x has been eliminated from the equation.


We can then, solve for  y and then substitute the result in to any of the equations to find x.


Hence the correct answer is option B

When x^3 + 2x^2 - 7x + a is divided by (x-2) the remainder is 4. Find the value of a. Please help
12345 [234]

Answer:

a = - 8

Step-by-step explanation:

A polynomial divided by factor (x - h) has a remainder given by f(h)

Here the divisor is (x - 2), thus f(2) gives the remainder, that is

2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder

8 + 8 - 14 + a = 4, that is

12 + a = 4 ( subtract 12 from both sides )

a = - 8

The equation for the motion of an object with constant acceleration is d=vt+0.5at² where d is distance traveled in ft, v is star
sasho [114]

The expression for the distance the car travels after t seconds is d = 200t + 50t²

<h3>Equation of motion </h3>

From the question, we are to write an expression for the distance the car travels after t seconds

From the given information,

The equation for the motion of an object with constant acceleration is

d = vt + 0.5at²

For the race car,

v = 200 ft/s

a = 100 ft/s²

Putting the parameters into the equation, we get

d = 200t + 0.5(100)t²

d = 200t + 0.5 ×100)t²

d = 200t + 50t²

Hence, the expression for the distance the car travels after t seconds is d = 200t + 50t²

Which expression is equal to 254−−√−424−−√ ?
hichkok12 [17]

Answer:

-2\sqrt{6}

Step-by-step explanation:

<u><em>The correct expression is</em></u>

2\sqrt{54}-4\sqrt{24}

we know that

54=(2)(3^3)=(3^2)(2)(3)=(3^2)(6)

24=(2^3)(3)=(2^2)(2)(3)=(2^2)(6)

substitute in the expression above

2\sqrt{(3^2)(6)}-4\sqrt{(2^2)(6)}=2(3)\sqrt{6}-4(2)\sqrt{6}=6\sqrt{6}-8\sqrt{6}=-2\sqrt{6}
