A cell phone costs $120. The price is reduced 30% for a sale. How much is the savings?

Answers

Answer:

the phone is 84 dollalrs

Step-by-step explanation:

Since 30% = 30/100 then we can transform it into a decimal:

30%=0.30

Now if we multiply 120•0.30, we will get how much we saved.

$36, we saved $36.

Bonus information:

If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.

Variable y varies directly with variable x, and y = 6 when x = 9. What is the value of x when y = 18?

Answers

x and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.

18=6*3 hence when y=18,x=9*3=27

x=27
so you can set up a proportion like
x/y=x/y
9/6=x/18
simplify 9/6=3/2
3/2=x/18
multiply both side by 18
(3x18)/2=x
54/2=x
x=27

What is the value of v? 2/9v + 4 - 2/3v = 5

Answers

2/9v + 4 - 2/3v = 5
2/9v  - 2/3v = 5 - 4
2/9v - 6/9v = 1
-4/9v = 1
v = 1 (-9/4)
v = -9/4
v = -2 1/4
the answer is v= -44/135

Joe has been given a treasure map on which he must plot three points. There is a portion of the treasure at each point. Point A is at (-4,0), Point B is at (-4,5), and Point C is at (4,2).
