Answer:           x= 7

Step-by-step explanation:

4x-7= -3x      First add -3x on both sides

+3x      +3x

7x  -7 = 0

     +7     +7               add 7 to both sides

7x      = 7  

x = 1               divide both sides by 7

Answer:

x = 1

Step-by-step explanation:

1. Add 3x to both sides of the problem

  • 4x + 3x - 7 = -3x + 3x
  • -3x + 3x cancels out and leaves us with zero
  • 7x - 7 = 0

2. Add 7 to both sides

  • 7x (- 7 + 7) = 0 + 7
  • -7 + 7 cancels out
  • 7x = 7

3. Divide both sides by 7

  • 7x/7 = 7/7
  • x = 1

To make sure our answer is correct we can plug in 1 to x in the problem

  • 4(1) - 7 = -3(1)
  • 4 - 7 = -3 : True

padilas [110]

Answer:

The tip would be worth $2.19

Step-by-step explanation:

x - is the full bill

1/20 x = $0.73

Solve for x:

Multiply both sides by 20.

<u>20</u>*(1/20 x) = <u>20</u>*(0.73)

x = 14.6

Now we just have to find 15% of x to find the tip.

3/20 (14.6) = 2.19

So, the tip would be worth $2.19

Need Help with 44.. picture above
Daniel [21]

Answer:

Ok:

Step-by-step explanation:

I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.
