Answer:
2
Step-by-step explanation:
2(3x²-5)-5=9
6x²-10-5=9
6x²-15=9
6x²=9+15
6x²=24
x²=24/6
x²=4
x=2
So 3150÷7=450 and then multiply 450×3= 1350. So 1350 people who jog regularly
Answer:
1, 4, 2, 3, 6, 5
Step-by-step explanation:
[- 9 + 0 = - 9] is 1. The identity property of addition rule.
[(- 9)(0) = (0)(- 9)] is 4. The commutative property of multiplication rule.
[(- 9)(1) = - 9] is 2. The identity property of multiplication rule.
[- 1( 4 . 9) = (- 1 . 4) 9] is 3. The associative property of multiplication rule.
[- 9 + 1 = 1 + (- 9)] is 6. The commutative property of performing addition rule.
[- 1 + (4 + 9) = (- 1 + 4) + 9] is 5. The associative property of addition rule. (Answer)
