17 = -13 - 8x .....add 13 to both sides
13 + 17 = -8x
30 = -8x...now divide both sides by -8
-30/8 = x...reduce
- 15/4 or -3 3/4 = x <===
Answer:
(-10)² = -10 x -10 = 100
- 10² = - (10 x 10) = - 100
Step-by-step explanation:
(-10)² = -10 x -10 = 100
- 10² = - (10 x 10) = - 100
Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
