Question

Evaluate: [(21 + 6) − 3*2] ÷ 9 • 2

4

4.6

1

52

Answer 1

is the 2 on the denominator? If so then it becomes 21/18 = 1.666 which doesnt seem to be one of the options...there might be a typo

Answer 2

I think that is how it's written purely for an order of operations question

[(21 + 6) − 3*2] ÷ 9 • 2

deal with the innermost parenthesis first

[(27) − 3*2] ÷ 9 • 2

now whats left in the brackets

[(27) − 6] ÷ 9 • 2

Finish up the brackets

21 ÷ 9 • 2

Now, since you only have multiplication and division left....go left to right

21 divided by 9 = 2.3

That times 2 = 4.6

Which is one of your choices!

Hope that helped!

Answer 3

the 2 is a exponint

Answer 4

So it should be

[(21 + 6) − 3²] ÷ 9 • 2

?

Answer 5

yes

Answer 6

then the answer is 4

Answer 7

If so then it comes out to

(27 - 9) = 18

now

18 ÷ 9 • 2

Left to right

18÷ 9 = 2

2• 2 = 4

Answer 8

Peter's age can be described as 2 more than 3 times his son's age. If his son's age is represented by the variable "s", write the algebraic expression representing Peter's age using "s".

Answer 9

Well Peter is 2 more ( +2 ) than 3 times his sons age (3s) so we can say that

P = 3s + 2
