So, you basically plug the values into the formula you have been given. D divided by T gives you the average speed.
We know the distance D is 145 miles and the Time T is 2.5 hours.

So, 145/2.5=58

Therefore, the cars average speed was 58 miles / hour

Cameron is playing 9 holes of golf. He needs a total of at most 15 over par on the last four holes to beat his best golf score.
Margaret [11]

Cameron is successful at beating his record since he only shot 9 over par on the last 4 holes.

To find this, first turn each score into a number. Over pars are positive and under pars are negative. This gives us the following expression.

+5 - 1 + 6 - 1 = + 9

Therefore, he stayed below the + 15 that he needed.

Solve 4(3x+3)=15x+7-3x+5
Flura [38]

Answer:

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

4(3x + 3) = 15x + 7 - 3x + 5

Step 2: Solve for <em>x</em>

  1. Distribute 4: 12x + 12 = 15x + 7 - 3x + 5
  2. Combine like terms: 12x + 12 = 12x + 12
  3. Subtract 12 on both sides: 12x = 12x
  4. Divide both sides by 12: x = x

Here, we can see that <em>x</em> would be infinite amount of solutions. We can plug in any number <em>x</em> and it would render the equation true.
