Answer:
x = -5
Step-by-step explanation:
Step 1: Write equation
-2x + 8 = 18
Step 2: Solve for <em>x</em>
- Subtract 8 on both sides: -2x = 10
- Divide both sides by -2: x = -5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-2(-5) + 8 = 18
10 + 8 = 18
18 = 18
Answer:
-47/100
Step-by-step explanation:
It would be distributive because you distribute what is in the parentheses
Probability of Reggae song: 2/7
Probability of Rock song: 3/6= 1/2
So the <span>probability that the first song is a reggae song and the second is a rock song: (2/7)*(1/2)= 2/14= 1/7

Answer:
A is b/c the 2 minutes and 54 seconds are 174 seconds and the .29 also gets carried over, so it is 174.29. (You are converting minutes to seconds [60 seconds=1 minute])
B the average time of the four runners would be 43.5725 seconds, b/c 174.29/4=43.5725
