Answer:

x=13

Step-by-step explanation:

mugs=x

key=y

x+y=21         8.5x2.75 =132.50

y=  -x+21

8.5x + 2.75 (-x + 21) = 132.50

8.5x - 2.75 + 57.75 = 132.50

5.75x = 74.75

x= 13

Answer:

he bought 13 coffee mugs and 8 key chains.

Step-by-step explanation:

How about we solve by simulataneousequation:

consider   coffee mug 'x' and key chain 'y'

there are total 21 items,

x+y = 21

=> x  = 21 - y .........................(i)

and

total cost is $132.50

8.5x + 2.75y = 132.5 .........(ii)

put value of x from eqn (i) into (ii):

8.5 ( 21 -y) + 2.75y = 132.50

=> 178.5 - 8.5y + 2.75y = 132.50

=> -5.75y = -46

 =>y = 8

Put vaklue of y back in (i):

x = 21 - y

=> x = 21 - 8 = 13

thus, x = 13

he bought 13 coffee mugs and 8 key chains.

Slav-nsk [51]

Answer:

Option c (Upper tailed) is the correct choice.

Step-by-step explanation:

Given that:

The average attendance is:

= 74,900

We will have to test:

⇒ H_0:\mu \leq \mu_0

or,

   H_0: \mu \leq 74,900

Verses,

⇒ H_1: \mu> \mu_0

or,

    H_1: \mu >74,900

The other given alternatives aren't connected to the given scenario. So the above is the correct one.

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. why?
Viktor [21]
Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.

It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.

If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.
