Answer:

4 mechanical pencils

Step-by-step explanation:

Then, $15.00 - $8.97= $6.05

If twice a​ number, added to 3 is divided by the number plus 7​, the result is five thirds. Find the number.
Alina [70]

Answer: 26

Step-by-step explanation:

Let the number be n.

Now,

twice a​ number =>> 2n

added to 3 =>> 2n + 3

is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3

(2n + 3) = (5 / 3) × (n + 7)

3 × (2n + 3) = 5 × (n + 7)

6n+9 = 5n + 35

6n - 5n = 35 - 9

n = 26

Answer:

radius is 2.5

volume of ice cream is 58.9 cm cubed

Step-by-step explanation:

to calculate the volume of a cone   v=pi x r^2 x (h/3)

v=volume

r=radius

h=height

^ means powers and roots

depth in cones is the same as height

v=3.14 x 2.5^2 x (9/3)

order of operations

v=3.14 x 2.5^2 x 3

v=3.14 x 6.25 x 3

v=19.625 x 3

v=58.875

round

v=58.9
