Well,

If a + b = 0, then that means that a is the opposite of b.  For example:
If a = 5, b = -5

You could also say that b = -a.

Explain or show how you could find 5 ÷ 1/3 by using the value of 5x3.​
erastova [34]

Answer:

20

You could find 5/⅓

by using 5 × 3

Knowing that:

Any number multiplied by 1, gives the number itself.

Dividing any number by itself gives 1.

Writing 5/⅓ as 5/⅓ × 1 doesn't change the value.

Then I can write 5/⅓ as

5/⅓ × (5×3)/(5×3) = 1

This can become

[5×(5×3)] / [(⅓) × (5×3)]

= 75/(15/3)

= 75/5

= 15

or

12/ 3/5

= [12/ (3/5)] × [(5×3)/(5×3)]

= 12×(5×3) / (3/5)×(5×3)

= (12×5×3) / [(3×5×3)/5]

= 180 / (45/5)

= 180 / 9

= 20

A survey of 100 random high school students finds that 85 students watched the Super Bowl, 25 students watched the Stanley Cup F
otez555 [7]

Answer:

Students did not watch either game = 10

Step-by-step explanation:

Total no. of students = 100

Students watched the Super Bowl = 85

Students watched the Stanley Cup = 25

Students watched both games = 20

Students did not watch either game = ( Total no. of students ) -  ( Students watched the Super Bowl )  + ( Students watched the Stanley Cup ) - ( Students watched both games )

Students did not watch either game = 100 - (85 + 25 - 20)

Students did not watch either game = 100 - 90

Students did not watch either game = 10
