<span>3x-5=5x+11

subtract 3x to both sides

</span>3x-5 - 3x =5x+11 - 3x

<span>simplify
-5 = 2x +11

answer is </span><span>D. -5=2x+11</span>

The equation that matches the same solution as 3x-5=5x+11  is \boxed{{\mathbf{Option D}}\to{\mathbf{-5=2x+11}}} .

Further explanation:

The expression is given as 3x-5=5x+11 .

Now, the above expression is simplified as follows:

\begin{aligned}3x-5x&=11+5\\-2x&=16\\x&=-\frac{{16}}{2}\\x&=-8\\\end{aligned}

Therefore, the value of x  for the given expression is -8 .

Now, the four options are given below.

\begin{gathered}{\text{OPTION A}}\to2x-5=11\hfill\\{\text{OPTION B}}\to3x=5x+6\hfill\\{\text{OPTION C}}\to3x+6=5x\hfill\\{\text{OPTION D}}\to-5=2x+11\hfill\\\end{gathered}

The simplified form of OPTION A 2x-5=11  is given below.

\begin{aligned}2x-5&=11\\2x&=11+6\\2x&=17\\x&=\frac{{17}}{2}\\x&=8.5\\\end{aligned}

The above solution x=8.5  of the expression 2x-5=11  does not match with the obtained solution x=-8 .

Therefore, OPTION A is not the correct answer.

The simplified form of OPTION B 3x=5x+6  is given below.

\begin{aligned}3x&=5x+6\\3x-5x&=6\\-2x&=6\\x&=-3\\\end{aligned}

The above solution x=-3  of the expression 3x=5x+6  does not match with the obtained solution x=-8 .

Therefore, OPTION B is not the correct answer.

The simplified form of OPTION C 3x+6=5x  is given below.

\begin{aligned}3x+6&=5x\\3x-5x&=-6\\-2x&=-6\\x&=3\\\end{aligned}

The above solution x=3  of the expression 3x+6=5x  does not match with the obtained solution x=-8 .

Therefore, OPTION C is not the correct answer.

The simplified form of OPTION D -5=2x+11  is given below.

\begin{aligned}-5&=2x+11\\-5-11&=2x\\-\frac{{16}}{2}&=x\\x&=-8\\\end{aligned}

The above solution  x=-8 of the expression -5=2x+11  matches with the obtained solution x=-8 .

Therefore, OPTION D is the correct answer.

Thus, the equation that matches the same solution as 3x-5=5x+11  is \boxed{{\mathbf{Option D}}\to{\mathbf{-5=2x+11}}} .

Nikitich [7]

Answer:

Area of nail's head  = 28.26 millimeter² (Approx.)

Step-by-step explanation:

Given:

Head of nail is circular

Diameter of nail's head = 6 millimeter

Find:

Area of nail's head

Computation:

Radius of nail's head = Diameter / 2

Radius of nail's head = 6 / 2

Radius of nail's head = 3 millimeter

Area of circle = πr²

Area of nail's head  = πr²

Area of nail's head  = (22/7)(3)²

Area of nail's head  = (22/7)(9)

Area of nail's head  = (3.14)(9)

Area of nail's head  = 28.26 millimeter² (Approx.)

A train leaves at 14:56 and arrives at 16:43. It travelled at an average speed of 135 km/h. How far did it travel? Give your ans
Firlakuza [10]

Answer:

240.8

Step-by-step explanation:

→ Calculate time taken

16:43 - 14:56 = 1 hour and 47 minutes

→ Write the speed formula and make distance the subject

Speed = Distance ÷ Time ⇔ Distance = Speed × Time

→ Convert 1 hour and 47 minutes into decimal format

1.78333333 or  1\frac{47}{60}

→ Substitute values into formula

135 ×  1\frac{47}{60}  = 240.75
