Answer: The number of rolls of paper is 2\dfrac{1}{2}.

Step-by-step explanation:  Given that Andy is hanging wallpaper in his kitchen. 6 rolls of wallpaper is used to cover 2\dfrac{2}{5} of the walls.

We are to find the number of rolls of paper used per wall.

We will be using unitary method to solve the given problem.

We have,

2\dfrac{2}{5}=\dfrac{12}{5}.

Now, number of rolls used to cover \dfrac{12}{5} of the walls = 6.

Therefore, number of rolls used to cover 1 wall is given by

\dfrac{6}{\frac{12}{5}}=\dfrac{5\times 6}{12}=\dfrac{5}{2}=2\dfrac{1}{2}.

Thus, 2\dfrac{1}{2} rolls of paper used per wall.

2/5 is the answer

steps;

first make the fraction as improper

2/5=12/5

divide

12/5by 6

Simplify 6(x + 2) + 7.
Elina [12.6K]

Answer:

6x+19

Step-by-step explanation:

First thing first, we need to multiply the 6 into the equation. We do this by multiplying the x and 2 by 6.

6(x+2)+7

Multiply

6x+12+7

Now we need to combine like terms by adding the 12 and 7

6x+19

There it is simplified.

Tracis Bank charges $2 for withdrawals at nonbank ATMs and a fee of $2.50 per month for debit card. last month she paid $10.50 i
anastassius [24]

Answer:

5 withdrawals

Step-by-step explanation:

Since $10.50 ends in $0.50, you know that she must have made at least one $2.50 transaction.

10.50 - 2.50 = 8

8/2 = 4 (she made four $2 transactions)

She made 4 $2 transactions and 1 $2.50 transaction.

4 + 1 = 5

She made 5 transactions total.

Andrea is given triangle ABC and told that a ^ 2 + b ^ 2 = c ^ 2 draws right triangle RTS with legs measuring a and b and hypote
kondaur [170]

Complete question is;

Andrea is given ABC and told that a² + b² = c². She draws right triangle RTS with legs measuring a and b and hypotenuse measuring 2. Which best describes what Andrea should

do in order to prove that ABC is a right triangle?

Answer:

Andrea should show that c = 2, so: ∡ABC = ∡RTS and ∡C = ∡S. Hence, ∡C is a right angled triangle, hence ΔABC is a right triangle

Step-by-step explanation:

In this question, we are told that the given sides of the triangle are a, b and c. Now, Andrea is able to draw the two sides of the right triangle with sides = a and b and the third, hypotenuse equal to 2. Since the length of the hypotenuse = 2, then we have;

2² = a² + b²

However, we are told that c² = a² + b²

Therefore, c = 2

Hence, Andrea should show that c = 2 so ΔABC = ΔRTS and ∡C = ∡S hence ∡C is a right angled triangle since it is the angle opposite to the hypotenuse c and therefore, ΔABC is a right triangle.

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x.
leva [86]

Let's set the measure of each angle equal to 540 degrees.

4x + 4x + 5x + 2 + 96 + 5x - 8 = 540

Combine like terms.

18x + 90 = 540

Subtract 90 from both sides.

18x = 450

Divide both sides by 18

x = 25
