Answer:
$2.90
Step-by-step explanation:
<u>Lets look at the information given:</u>
Scott made 3 necklaces
$14.40 is the cost for both the beads and pendants for all 3 necklaces
$5.70 was the cost of just beads for all 3 necklaces
Each necklace has 1 pendant
The first step to solving this equation is subtracting the cost of the beads from the total cost for the necklaces:
$14.40 - $5.70= $8.70
Now we know that cost for the 3 pendants for all 3 necklaces was $8.70, but we need to find how much EACH pendant costs. To find out, we simply divide the total cost for all 3 pendants by 3:
$8.70 ÷ 3 = $2.90
So each pendent costs $2.90
Given that the monthly cell phone bill is determined by a fixed monthly fee of $35
for 300 anytime minutes and $.40 for each additional minute used.
Dependent variables can be the result of more than one independent
variable.
Consider your phone bill as presented above. Aside from being
charged for minutes over 300, you are charged $1.25 for each directory
assistance call and $.75 per minute for long distance roaming calls. You
also have to contribute at least $1.50 to the federally required
Universal Service Fund per month and this value may vary on your phone
bill but is not an independent variable.
<span>To write
an equation expressing your monthly cost using the below independent
and dependent variables.
Let x = additional minutes used, then the cost for additional minutes used is given by 0.4x.
Let d = number
of directory assistance calls made, then the cost for directory assisitance is given by 1.25d.
Let r = number of long distance
minutes used, then the cost for long distance minutes is given by 0.75r.
Let u = USF monthly charge.
Let y = total monthly bill, therefore the total monthly bill is given by
y = 0.4x + 1.25d + 0.75r + u</span>
-2x+4=3
move the 4
-2x+4=3
-4 -4
-2x=-1
then you would move the -2 by using division
-2x=-1
__ __
-2 -2
x=0.5
Answer:
<h2>x=25</h2>
Step-by-step explanation:
according to the question
the equation is
130+2x=180
2x=180-130
2x=50
x=25
Answer:

Step-by-step explanation:
Equilateral triangles have 3 equal sides.
Thus, perimeter of triangle
= 3(2x -3)
= 3(2x) +3(-3) <em>(</em><em>expand</em><em>)</em>
= (6x -9) inches
Given that the perimeter is 83 inches,
6x -9= 83
6x= 83 +9 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
6x= 92
