Answer:

x=4.

Step-by-step explanation:

Let's solve your equation step-by-step.

5/15=x/ x+8

Step 1: Cross-multiply.

5/15=x/ x+8

5*(x+8)=x*(15)

5x+40=15x

Step 2: Subtract 15x from both sides.

5x+40−15x=15x−15x

−10x+40=0

Step 3: Subtract 40 from both sides.

−10x+40−40=0−40

−10x=−40

Step 4: Divide both sides by -10.

−10x−10=−40−10

Then your answer will be x=4.

Y = 2x + 3<br> y = 3x - 1
lilavasa [31]

Answer:

 x= 4 and y= 11

Step-by-step explanation:

The problem to solve is:

y = 2x + 3 (equation 1)

y = 3x - 1 (equation 2)

Since y = 3x - 1 Solve x from equalution 1

3x - 1 = 2x + 3

3x - 2x = 3 + 1

x = 4

Since x is 4, solve for y

y  = 3x - 1

y = 3(4) - 1

y = 12 -1

y = 11

x =4 and y =7

Monica [59]

Answer:

A) 420 seconds = 7 minutes

B) 8 times

Step-by-step explanation:

A) After how many second would all three things happen together again?

Solution:

His clock ticked every 5 seconds , a tap was dripping every 7 seconds and     his pet dog snored every 12 seconds. It all happens simultaneously = 5*7*12=420 seconds

B) How many times would all three things happen together again between    midnight and one o'clock

Since all these events happen together after every 420 sec = 7 mins and there are 60 mins between midnight and 1 o'çlock , thus 60/7 = 8 times ....
