There are 187 nickels and 66 dimes in the jar.
Step-by-step explanation:
Given,
Total coins = 253
Value of coins = $15.95 = 15.95*100 = 1595 cents
Value of each nickel = 5 cents
Value of each dime = 10 cents
According to given statement;
x+y=253 Eqn 1
5x+10y=1595 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 5
Putting y=66 in Eqn 1
There are 187 nickels and 66 dimes in the jar.

Answer:
From the given picture we can see that , 3 teaspoons = 1 table spoon.....(1)
or 3t=b..(2)
6 teaspoon= 2 tablespoon or 6t=2b
9 teaspoon= 3 table spoon or 9t=3b
Therefore the ratio of teaspoon to tablespoon t:b= 3:1...........(from (1))
Now, 1 tea spoon=..............[divide 3 on both sides of (1)]
or
The equation to show the relation between teaspoons and table spoon is given by (2)
3t=b
