3X + 8 - X = 4 - 2X + 32 find x

Mathematics

Mashcka [7]3 years ago

Answer:

x=7

Step-by-step explanation:

First simplify as much as you can about the equation on both sides:

3x+(-x)+8=4+32+(-2x)

2x+8=36-2x

Now subtract 8 from both sides and add 2x to both sides. Simplify as well.

2x+2x=36-8

4x=28

Finally, divide both sides by 4.

x=7.

Answer: X=7

Step-by-step explanation:Let's solve your equation step-by-step.

3x+8−x=4−2x+32

Step 1: Simplify both sides of the equation.

3x+8−x=4−2x+32

3x+8+−x=4+−2x+32

(3x+−x)+(8)=(−2x)+(4+32)(Combine Like Terms)

2x+8=−2x+36

2x+8=−2x+36

Step 2: Add 2x to both sides.

2x+8+2x=−2x+36+2x

4x+8=36

Step 3: Subtract 8 from both sides.

4x+8−8=36−8

4x=28

Step 4: Divide both sides by 4.

4x =28

4x/4=x 28/4

=

28 /4=7

The perimeter of the flag is 2080 ft what is the flags width and length of the length is 420 ft greater than the width
hram777 [196]

Answer:

The length of the flag is 730 ft and the width is 310 ft

Step-by-step explanation:

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

The perimeter of the flag is 2080 ft what is the flags width and length <u>if</u> the length is 420 ft greater than the width

Let

L ----> the length of the flag

W ---> the width of the flag

we know that

The perimeter of the flag (rectangle) is equal to

P=2(L+W)

we have

P=2,080\ ft

so

2,080=2(L+W)

1,040=L+W ----> equation A

L=W+420 ---> equation B

Solve the system by substitution

substitute equation B in equation A

1,040=(W+420)+W

solve for W

1,040=2W+420

2W=1,040-420

2W=620

W=310\ ft

<em>Find the value of L</em>

L=W+420 ----> L=310+420=730\ ft

therefore

The length of the flag is 730 ft and the width is 310 ft

Change 240 to radian measure in terms of pi
Vera_Pavlovna [14]
To change a degree measure to a radian measure, we multiply by (π/180). So 360° becomes 2π radians, and 240° becomes 4π/3.
