Answers:

14 + 18 ÷ 2 x 18 – 7 = 169

  • 14 + 9 * 18 - 7
  • 14 + 162 - 7
  • 169

60 – 9 x 8 ÷ 8 x 6 = 6

  • 60 - 72 / 8 * 6
  • 60 + -216/4
  • 60 - 54
  • 6

15 x 10 + 12 ÷ 3 + 9 = 163

  • 150 + 12 / 3 + 9
  • 150 + 4 + 9
  • 163

(10 ÷ 5)3 + 100 – 9 x 11 = 7

  • 2 * 3 + 100 - 9 * 11
  • 6 + 100 - 99
  • 7

8 x 4 + 9 – 9 + 18 = 50

  • 32 + 9 - 9 + 18
  • 41 - 9 + 18
  • 32 + 18
  • 50

3 x 8 x 2 – 42 + 5 = 11

  • 24 * 2 - 42 + 5
  • 48 - 42 + 5
  • 11

8/7 divided by 5/8.
maksim [4K]

Answer:

64/35

Step-by-step explanation:

To divide fractions, multiply the first fraction by the second fraction's reciprocal.

The reciprocal of a fraction is just the top and bottom number switched.

So the reciprocal of 5/8 would be 8/5.

Now, you can multiply 8/7 by 8/5.

This gives you 64/35.

And that's it!

The explicit rule for a sequence is given. an=4n−1 What is the recursive rule for the sequence?
Gnom [1K]

Answer:

a_{n+1}=a_n+4

Step-by-step explanation:

Have in mind the definition of the term a_n=4\,n-1, and now work on what the term a_{n+1} is based on the previous definition:

a_{n+1} = 4\,(n+1)-1\\a_{n+1}=4\,n+4-1

In the next step do NOT combine the numerical values, but try to identify the a_n term (4\,n-1) in the expression (notice the use of square brackets to group the relevant terms):

a_{n+1}=4\,n+4-1\\a_{n+1}=[4\,n-1]+4\\a_{n+1}=a_n+4

So now we have the term "a_{n+1}" defined in a recursive manner based on the previous term "a_n"

The theater sells two types of tickets: adult tickets for $15 and
UkoKoshka [18]

Answer:

68

Step-by-step explanation:

Let x=adult tickets and y=child tickets

1) 15x+11y=1889

2) x+y=147

multiply equation 1 by -1/11 on both sides to get:

-(15/11)x-y=-171.73

add new equation with equation 2 to get

-4/11x=-24.73

Isolate x to get:

x=67.99999
