Answer: 4.3
Step-by-step explanation: To find the range you have to subtract the highest number by the lowest number. So you'd subtract 2.6 by -1.7. And since -1.7 is already a negative number, it would get turned into a positive.
Step-by-step explanation:
Did you mean:
= (a - b)(a + b)
= a.a + b.a - b.a - b.b
= a² + ba - ba - b²
= a² - b²
The answer is 160 because you add the two together

Answer: FALSE. Paul spent $9 on the student discount card.
Step-by-step explanation:
Hi, to answer this question we have to write an equation using the information given:
- <em>Price of the student discount card: x
</em>
- <em>Price of each bus pass: $1.60
</em>
- <em>Number of bus passes bought: 16
</em>
- <em>Total cost: $34.60
</em>
So, we have to multiply the number of bus passes (16) by the cost of each pass (1.60) and adding the cost of the discount card (x). That expression is equal to the total cost (34.60)
Mathematically speaking:
x + 16( 1.60) = 34.60
Solving:
x+ 25.6 =34.60
x= 34.60-25.6
x= 9
So, the answer is FALSE. Paul spent $9 on the student discount card.
