What equation can be used to find n, the number of nickels in the collection ?
Answers
Given, Bodhi has a collection of 175 dimes and nickel. If she has n numbers of nickel. Then,
The number of dimes coin= 175-n.
The collection is worth $13.30.
1 nickel is worth five cents. So, n nickel will worth 0.05n.
Similarly 1 dime is worth 10 cents. So, 175-n dimes will worth 0.1(175-n).
Since the total worth is $13.30. So, we can set the equation as follows:
0.1(175-n)+0.05n=13.13.
Hence, the last option is the correct choice.

The ticket for an adult costs $10 and the ticket for a child costs $7
- Let adults tickets be a
- Let children tickets be c
Based on the information given, the equation to solve the question will be:
2a + 4c = 48
5a + 2c = 64
Multiply equation i by 5
Multiply equation ii by 2
10a + 20c = 240
10a + 4c = 128
Subtract the equations
16c = 112
c = 112/16
c = 7
The ticket for a child is $7
Since 2a + 4c = 48
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
a = 20/2
a = 10

Answer:
The price for one adult is $10 while the price for one child is $7
Step-by-step explanation:
Let
price for an adult = a
price for a child = b
2a + 4b = 48.............(i)
5a + 2b = 64.............(ii)
make a subject of the formula in equation (i)
2a = 48 - 4b
divide through by 2
a = 24 - 2b
Insert the value of a in equation (ii)
5(24 - 2b) + 2b = 64
120 - 10b + 2b = 64
collect like terms
- 8b = 64 - 120
-8b = -56
divide both sides by -8
b = 7
insert the value of b in equation(i)
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
divide both sides by 2
a = 10
The price for one adult is $10 while the price for one child is $7

So, the triangle may have sides 3, 3, 13 OR 3, 13, 13
The triangle inequality theorem states that one side of a triangle is less than the sum of the other two.
3, 3, 13 cannot be the sides of any triangle because 13 is not less than 3 + 3 which is 6.
3, 13, 13 are the lengths of the triangle with 13 being the length of the third side.
This can be reasoned in that a base of 13 inches is too wide for two sides of 3 inches to meet and create a triangle, but a base of 3 inches would make a base small enough for two sides of 13 inches to meet and form an isosceles triangle.

Adrian knows this because whenever you divide something less than the number you are dividing, in this case, then the quotient will be less than one. If you divide something that is greater than the number you are dividing, than in this case, the answer will be greater than one.
