Answer:
10 visors
Step-by-step explanation:
Make an equation
Each visor, v costs $6, and there is a $5 fee regardless of the amount of visors purchased. This must be equal to $65
6v+5=65
Now, solve for v
Subtract 5 from both sides
6v=60
Divide both sides by 6
v=10
You can buy 10 visors
Answer:
The number of nickels is 45 and the number of dimes is 72.
Step-by-step explanation:
Let
x ----> number of nickels
y ----> number of dimes
Remember that


so
------> equation A

------> equation B
<em>Solve the system by substitution</em>
we have
------> equation A
------> equation B
Multiply both equations by 100 both sides
---->
--> equation C
----> equation D
substitute equation C in equation D

solve for y




Find the value of x




<em>Alternative Method</em>
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
the solution is the point (45,72)
therefore
The number of nickels is 45 and the number of dimes is 72.
Answer:
To find the sum of an infinite geometric series having ratios with an absolute value less than one, use the formula, S=a11−r , where a1 is the first term and r is the common ratio.
4/16 in simplest form is 1/4 because 4 goes into 4 1 time and 4 goes into 16 4 times
Not a solution I believe.
