The answer is (3) because when all the letters are turned into numbers then solved it becomes [-4+10+(-9)] then you have to turn it into a positive because of the lines.

Answer:

  1. y= -12
  2. x = 7
  3. q = -1
  4. x = 24

Step-by-step explanation:

1. ..............................................

  • 6(y + 7) = 2(y - 3)
  • 6y + 42 = 2y - 6
  • 6y - 2y = -6 - 42
  • 4y = -48
  • y = -12

2...............................................

  • 3x + 2(x - 5) = 25
  • 3x + 2x - 10 = 25
  • 5x = 25 + 10
  • 5x = 35
  • x = 7

3 . ..............................................

  • 10q + 3q + 5 = 2(q - 3)
  • 13q + 5 = 2q - 6
  • 13q - 2q = -6 - 5
  • 11q = -11
  • q = -1

4. ..............................................

  • 1/3(x + 6) = 2/3(x - 9)
  • 3*1/3(x+6) = 3*2/3(x - 9)
  • x + 6 = 2(x - 9)
  • x + 6 = 2x - 18
  • 2x - x = 6 + 18
  • x = 24

If rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated, how many hours must have passed if there are
zavuch27 [327]

Given :

Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.

To Find :

How many hours must have passed if there are 5 inches of rain .

Solution :

Let , after x hours rain accumulated is 5 inches .

We know , general equation of line :

y = mx +c

Here , m = 0.5 and c = 1 .

So , equation of rain accumulated is :

y=0.5x+1

Now , putting value of x = 5 hours .

We get :

y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches

Hence , this is the required solution .

C(x-2)-5=b(x-3), solve for x
xeze [42]

Answer:

x =  (2c - 3b + 5) / (c - b).

Step-by-step explanation:

c(x - 2) - 5 = b(x - 3)

cx - 2c - 5 = bx - 3b          Bring the terms in x to left side:-

cx - bx  - 2c - 5 = -3b        Bring  other terms to right side:-

cx - bx = 2c  - 3b  + 5

x(c - b) =  2c  - 3b  + 5         Divide both sides by c - b:-

x =  (2c - 3b + 5) / (c - b).
