We are given that
Shopkeeper has six coins
total number of coins =6
we know that
there are four types of coins
(1) cents
1 cent =1 cent
(2) nickels
1 nickel =5 cents
(3) dimes
1 dimes =10 cents
(4) quarters
1 quarter = 25 cents
so, we can use trial and error method
Since, nickels , dimes and quarter are multiple of 5
and there 38 cents
so, three coins must be cent
number of cent coins =3
so, the remaining cent = 38-3=35
so, possible coins can be 1 quarter and 2 nickels
1 quarter + 2 nickels =25+2(5)=35
so, coins were
Number of cents =3
Number of nickels =2
Number of dimes =0
Number of quarter =1..................Answer
Number 3 is x=3 Number 5 is x=-1 Number 7 is x=9 Number 9 is x=10
Answer:
b) 4/52
Step-by-step explanation:
Since there are only 4 playing cards in a full deck that are labeled '2', and there are 52 cards in total - then there is a 4 out of 52 chance that a '2' card will be selected!
Answer:
y =
x
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use either of the 2 given points
Using (- 9, - 3), then
k =
=
= 
y =
x ← equation of function
