Answer:

50.24 centimeters squared

Step-by-step explanation:

The diameter (d) is 8 which means the radius is 4 (8/2)

we use the formula pi x radius^2

It says to use 3.14 for pi

so the equation is 3.14(4)^2=3.14 x 16 = 50.24

What is the best first step for solving the given system using substitution while avoiding fractions? =9x+4x=10 -9x+3y=3
aivan3 [116]

Answer:

  Solve for y in the second equation

Step-by-step explanation:

We assume your system is ...

  • -9x +4y = 10
  • -9x +3y = 3

Dividing <em>the </em><em>second equation</em> by 3 gives ...

  -3x +y = 1

so an expression for y without fractions can be found by <em>solving for y</em>, that is, by adding 3x:

  y = 3x +1

_____

<em>Comment on alternate solution</em>

We'd be tempted to solve the first equation for -9x and substitute for that.

  -9x = 10 -4y

  (10 -4y) +3y = 3 . . . . . substitute for -9x

  -y = -7 . . . . . . . . . . . . . simplify, subtract 10

  y = 7 . . . . . . . . . . . . . . multiply by -1

Answer:

Rewrite the equation as 4L+4W=P.

4L+4W=P

Subtract 4L from both sides of the equation.

4W=P−4L Divide each term by 4 and simplify.

W=P/4−L
