Answer:
(-2,1)
Step-by-step explanation:
The bracket is an opened interval
zero is neutral either positive or Negative
so the range of values in (-2,1) is -1,0 with corresponding values 2 each
hence, they're positive
Order of operations
PEMDAS
do parntheases
then exponents
then mutiply or divide, whichever coms first
then addd or subtract, whichever comes first
so
when doing parenthases, simplify innermost parenthsees first
so
2(18-(5+9)/7)
innermost is (5+9)=14
now we gots
2(18-(14)/7)
we can distribute or multiply the invisible -1 in front of the 14
2(18-14/7)
now divide because division comes before adition
remember that it is -14/7, not just 14/7 because the negative is part of the 14
2(18-2)
now simplify parenthasees
18-2=16
so
2(16)
multiply
32
the result is 32
11 5/8 in = 11.625 in
9 3/4in = 9.75 in
10 1/2 in= 10.5 in
11.625+9.75+10.5= 31.875in
To find the average divide the total of inches by the amount of pieces there are to find the average:
31.875 / 3 = 10.625in
Answer:
.
Step-by-step explanation:
We have been given that a store's profit P varies directly with the number of items n that they purchase from a warehouse.
We know that two proportional quantities are in form
, where y is directly proportional to x ad k is constant of variation.
Upon substituting our given variables, we will get:

We are also told that Greg's gadgets buys 75 Wacky Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190.50. Let us find constant of proportionality.



Therefore, our required equation would be
