If a = 1, find the values of b, c and d that make the given expression equivalent to the expression below.

vlada-n [284]

Answer:

To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.

Once you have simplified the expression, you get

-x-9/2x-4

But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write

x+9/-(2x-4) = x+9/-2x+4

So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.

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
