Answer:

  t = 2 units

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  AD +DB +BE +EC +AC = 48 = 3t +3t +4t +4t +7t +6

  42 = 21t . . . . . . subtract 6 and simplify

  42/21 = t = 2 . . . . . . divide by the coefficient of t

Hello :D

£1.45 + £2.85 = £4.30

£4.30 + £1.95 = £6.25

£6.25 to the nearest pound = £6.00

Answer: Selling fees = £6 (rounded to the nearest pound)

Step-by-step explanation:

Given information

Insertion fee = £1.45

Enhanced advert = £2.85

Selling fee = £1.95

Given expression deducted from the given information

Total = insertion + enhanced advert + selling

Substitute values into the expression

Total = (1.45) + (2.85) + (1.95)

Simplify by addition

Total = 4.3 + (1.95)

Total = 6.25

The solution to the expression (4k + 2 ) ÷ 10 when k = 12 is 5

From the given expression, we are to solve for (4k + 2) ÷ 10

When

What we are going to do is that we will replace k with 12 wherever we see (k) in the expression given

∴

= (4k + 2 ) ÷ 10

= (4(12) + 2 ) ÷ 10

= (48 + 2) ÷ 10

= (50) ÷ 10

= 5

Answer:

A = W² + 6W

Step-by-step explanation:

The width is W.

The length is 6 units greater than the width, so the length is W + 6.

The area is the product of the length and width.

A = (W + 6)W

A = W² + 6W

Answer:

Does the side on which you choose to isolate the variable affect the solution?

Why might you choose one side over the other?

The answer is x=34 degrees.

The answer you are looking for is x=34.

Solution/Explanation:

First things first, we need to understand that the sum of the angles of a triangle is 180°. We can apply this fact for the problem.

So, that means that the sum of all of the angles of this triangle is 180°.

So, therefore, we can formulate an equation:

2x+20+2x-10+x=180.

So, we now have our expression.

Now, all we need to do is simplify it.

Combining similar-like terms,

2x+2x+x+20-10=180.

Simplifying it now,

5x+10=180.

Subtracting 10 from both sides of the equation,

5x+10-10=180-10.

5x=170.

Finally, dividing both sides by 5,

5x/5=170/5.

x=34.

So, therefore the final answer is x=34.

I hope that this has helped you. Enjoy your day, and take care!

Answer:

149+(13x+5)=180

154+13x=180

13x=26

x=2

Answer:

see explanation

Step-by-step explanation:

The 2 angles are adjacent on a straight line and sum to 180° , then

149 + 13x + 5 = 180 , that is

154 + 13x = 180 ( subtract 154 from both sides )

13x = 26 ( divide both sides by 13 )

x = 2

Then

unknown angle = 13x + 5 = 13(2) + 5 = 26 + 5 = 31°
