Let n = the number of nickels that Ari has.
Let p = the number of pennies that Ari has.
The total number of coins she has is 22.
n + p = 22
We have our first equation... But we another one to solve this.
Each penny is going to be $0.01 and a nickel is work $0.05.
And the total is $0.54
Our second equation. 0.05n + 0.01p = 0.54
n + p = 22
0.05n + 0.01p = 0.54
Multiply the top by -0.05
-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54
The n terms cancel out.
-0.04p = -0.56
p = 14
Substitute p back into the top equation.
n + 14 = 22
n = 8
So, Ari has 8 nickels and 14 pennies.
The number of even positive integers less than a.b, i.e 90, is 45.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.
Given that
a = 7 and b = 13
⇒ ab
Substitute the values of a and b in the above expression,
⇒ (7)(13)
⇒ 91
Since the number of even positive integers is less than
⇒ ab > even positive
⇒ 90 > even positive
since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.
Thus, the number of even positive integer less than a.b, i.e 90, is 45

Answer: The equation that has a graph which is a parabola with a vertex at (5, 3) would be y = (x – 5)^2 + 3. The general form of a parabola which the vertex is not in the origin is expressed as y = a(x - h)^2 + k where (h,k) represents the vertex.
Answer:
3x-2y=-28
Step-by-step explanation:
0.60-0.40=0.20
3.80-3.20=0.60
0.60 divided by 0.20=3
Hence, each student got 3 toppings each.
hope it helps:))
