Answer:

11x -4

Step-by-step explanation:

We add up all the sides to find the perimeter of the triangle

4x+1  + x-7  + 6x+2  = Perimeter

Combine like terms

4x+x+6x  +1-7+2

11x -4

Answer:

  11x -4

Step-by-step explanation:

The perimeter (P) is the sum of the three sides, which is ...

  P = (4x +1) +(x -7) +(6x +2)

  P = (4+1+6)x +(1 -7 +2)

  P = 11x -4

Hamish and Harry work as plumbers. Harry earns a dollar more than the amount Hamish earns per hour. The amount Harry earns per h
natulia [17]

Answer:

Hamish and Harry work as plumbers. Harry earns a dollar an hour more than 5/4 the amount hamish earns per hour. harry earns per hour is 2$ less than 7/5 the amount hamish earns per hour. how much do each of them make an hour

Step-by-step explanation:

Let

x is the  amount Harry earns 

y is the amount Hamish earns 

x=(5/4)y+1 ⇒ (x-1)*4/5 = y-------- equation 1

x=(7/5)y-2⇒ (x+2)*5/7 = y-------- equation 2

equals 1 and 2

(x-1)*4/5 = (x+2)*5/7

(4x-4)/5 = (5x+10)/7

(4x-4)*7 = (5x+10)*5

28x-28 = 25x+50

28x-25x = 50+28

3x = 78

x = 26

substitute x = 26 for y=(x-1)*4/5

y = (x-1)*4/5

y =  (26-1)*4/5

y = 20

the answer is

<h3>Harry earns $26 an hour</h3><h3>Hamish earns  $20 an hour</h3>

What is x?? I'm so confused!
LiRa [457]

Answer:

x = 468%

Step-by-step explanation:

I see a proportion here.

we want to solve for the variable x in the proportion:

18% / (2 weeks) =   ( x %) / (52 weeks)

here we should multiply 52 to boths sides

(52 weeks) * 18%  / (2 weeks) =   x %

26  * 18% =  x %

x = 468 %
