4x +3=15 is the equation ..... You do not have to solve it

You can model this with the equation 4x+3=15 since it is a number (x) times 4 with 3 added and equals 15.
Subtract 3 from both sides
4x=12
Divide both sides by 4
x=3

Shonda made a model of a solid ice cream cone with a spherical scoop of ice cream on top, made out of clay.
IrinaVladis [17]

How sad, that you didn't include the list of choices.

The volume of the cone is    (1/3) x (π) x (radius²)  .

The volume of the sphere is  (4/3) x (π) x (radius³) .

Expand the binomial (2x+5)^5
Whitepunk [10]
That would simplify to 32x^5+400x^4+200x^3+5000x^2+6250x+3125
You would do that because you have to write it repeatedly as (2x+5)(2x+5) and so on.

Michael read 135 pages in 1 1/2 hours, Select all of the rates that are equivalent to this rate
devlian [24]

The rates that are equivalent to this rate is 90 pages/hr

<h3>Rate of change</h3>

The rate is the number of pages Michael read in 1 hour.

If he read 135 pages in 1 1/2 hours then;

  • 135 pages = 1.5 hours

To determine the rate, we will have:

  • x = 1 hour

Divide both expressions:

135/x = 1.5/1

1.5x = 135

x = 135/1.5

x = 90

Hence the rates that are equivalent to this rate is 90 pages/hr
