Solve for w by simplifying both sides of the equation, then isolating the variable.
w=13
Answer: She will pay $52.68, including taxes
Step-by-step explanation: One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:
can = 3 x 4 = 12
One tennis racket is $43 but it has a discount of 15%:
discount = 0.15 x 43 = 6.45
total racket = 43 - 6.45 = 36.55
Elena will have to pay:
pay = 12 + 36.55 = 48.55
She will also have to pay taxes, which are 8.5% over the price she paid:
pay + tax = 48.55 x 0.085 = 4.13
total to pay = 48.55 + 4.13 = 52.68
Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
Answer:
C = 14 pi inches
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
49 pi = pi r^2
Divide each side by pi
49 pi/pi = pi /pi r^2
49 = r^2
Take the square root of each side
7 = r
The circumference is given by
C = 2 * pi *r
C = 2 * pi *7
C = 14 pi inches
This would be true.
the word output automatically assumes that it’s a fraction or an equation to a fraction.
Answer:
$6.10
Step-by-step explanation:
Given the fabric store sells the fabric for $6.97 per yard
Given that a customer buys 7/8 yard of fabric.
Let the cost the customer pays be x then
on cross multiplication we get
x=6.01
Therefore the amount the customer should pay is $6.01
