Isaiah And Cooper work at a dry cleaner Ironing shirts.isaiah can iron 25 shirts per hour, and Cooper can iron 30 shirts per hou
neonofarm [45]

Answer:

Step-by-step explanation:

340/25 = 13.6 = 13 hours and 10 min

30 x 13.6 = 408 hours

25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.

Step-by-step explanation:

Isaiah ironing rate per hour = 25 shirts

Cooper ironing rate per hour = 30 shirts

Total shirts pressed = 340

Let,

Isaiah´s number of hours = x

Cooper's number of hours = y

According to given statement;

25x+30y=340   Eqn 1

Hudson worked twice many hours as grace.

y = 2x    Eqn 2

I WILL GIVE BRAINLIEST The area of the surface of the trampoline (square) is equal to twice its perimeter. Find the dimensions.
Brums [2.3K]
Given that the area is equal to twice the perimeter and the dimensions are:
length=4x ft, width=(x+6) ft
the perimeter will be:
P=2(L+W)
P=2(4x+(x+6))
P=2(4x+x+6)
P=2(5x+6)
P=(10x+12)

Area of the rectangle is:
A=4x(x+6)
A=4x²+24x
but:
2P=A
thus
2(10x+12)=4x²+24x
20x+24=4x²+24x
thus
4x²+4x-24=0
x²+x-6=0
x²-2x+3x-6=0
x(x-2)+3(x-2)=0
(x-2)(x+3)=0
thus the answer is:
x=-3 or x=2
thus
length=4x=4*2=8 ft
width=(x+6)=(2+6)=8 ft
