Answer:

<X =48

<Y  =96

<Z = 36

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

3.2n + 6.4n +2.4n = 180

Combine like terms

12n = 180

Divide each side by 12

12n/12 =180/12

n =15

<X = 3.2 n = 3.2 *15 =48

<Y = 6.4 n = 3.2 * 15 =96

<Z = 2.4 n = 2.4 * 15 =36

<Y = 6.4(15) = 96

Hitman42 [59]

The amount each friend does pay is £9.75

<h3>How to calculate the pay of each friend using fractions and arithmetic operations?</h3>

We are going to find 5% of the total amount paid and divide it by the numbers of all the friends to determine the amount paid by each one of them.

From the given information:

  • The 5% of 130 = £6.5
  • Total amount paid = £130 + £6.5 = £136.5

Therefore, the cost of each friend is = \dfrac{136.5}{14}

The cost of each friend = £9.75

Answer:

w=9x+4


Step-by-step explanation:

2(3x-3+w)=12x+2

6x-6+2w=12x+2

subtract 6x for both sides

-6+2w=18x+2

add 6 for both sides

2w=18x+8

Divide by 2 to find w

w=9x+4
