58 = 12 + 2 p     solve for p, the price of a pass

2 2/3 doz = 32

1 doz       = 12

2 1/3 doz = 28                GCF  of   32  12   28   =  4   bags

x = smaller number

l = larger number = x + 9             summed, they equal 47

x      +      (x + 9)      =   47               solve for 'x'    the smaller number

First one:

Gavin needs at least 80 dollars     sooooo   >= 80       

  starts with  8 dollars and adds  9 dollars per n hour

     8 + 9n >= 80

           9n >=72

             n >= 8            Answer A

Second one :

  Pedro wants to spen = to or less than 70    so   <= 70

    9.94 shipping per order    and  10.01  per  p     is the total cost

         9.94   + 10.01 p  <= 70

                      10.01 p <= 60.06

                           p <= 6

The answer is 1425.

Thks, EP......I never remember this method, but it's a good one....!!!

Here is another method :

x   = 5.228

100x = 522.8888.....

1000x = 5228.8888.....

1000x - 100x =  900x =   5228.8888....   - 522.8888....    = 4706

900x = 4706

x = 4706/900   simplify as needed                     (=  5  103/450) 

Same thing here, KK....   what do YOU think the answer might be?   Did you read the other answers to learn how to do these Q's ?

Pedro wants to buy some shirts over the Internet. Each shirt costs $10.01 and has a shipping cost of $9.94 per order. If Pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy?

A.9.94 + 10.01p ≤ 70, so p ≤ 6

B.9.94 − 10.01p ≤ 70, so p ≤ 7

C.9.94p + 10.01p ≤ 70, so p ≤ 8

D.9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to earn $9 per hour. Which inequality shows the minimum number of hours, n, that Gavin should work as a babysitter to earn enough to buy the fish tank

A.8 + 9n ≥ 80, so n ≥ 8

B.8 + 9n ≤ 80, so n ≤ 8

C.9n ≥ 80 + 8, so n ≥ 9.8

D. 9n ≤ 80 + 8, so n ≤ 9.8

KK....this is VERY similar to your other questions......   what have you tried to solve this one ?

42 + 2n  ≥ 80

And

2n ≥ 80 - 42

2n ≥ 38

n ≥ 38 / 2

n ≥ 19

B.42 + 2n ≥ 80, so n ≥ 19

9.5 for children   +  9.5 for adults  =

9.5c + 9.5a  =

9.5 ( c + a)

We don't need to worry about the "5"  part, yet

1)  Take 228  and subtract  the non-repeating part of the decimal  =  228- 22 = 206....this is our numerator

2) In the denominator, write the same number  of 9's as the repeating part  of the decimal= 9

    And write the same  number of 0's as the non-repeating part  of the decimal = 00

So  .228 (8 repeating)  =   206 / 900 =   103 / 450

So we have

5 + 103 / 450   =  2343 / 450

1741/333 = 576/333

Use cos law

c^2 = a^2 + b^2 - 2ab cos c

example   to find cos a

  8^2 = 5^2 + 7^2  - 2 ( 5 )( 7) cos a         solve for cos a       the others are similar
