Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

-4p + 9 = -5

<u>Step 2: Solve for </u><em><u>p</u></em>

  1. Subtract 9 on both sides:                     -4p = -14
  2. Divide -4 on both sides:                       p = 7/2

<u>Step 3: Check</u>

<em>Plug in p into the original equation to verify it's a solution.</em>

  1. Substitute in <em>p</em>:                    -4(7/2) + 9 = -5
  2. Multiply:                               -14 + 9 = -5
  3. Add:                                     -5 = -5

Here we see that -5 does indeed equal -5.

∴ p = 7/2 is the solution to the equation.

Stels [109]

we know that

diameter of the base of a cylindrical can= 4 in----------> r=2 in

h=6.5 in

[surface area]=2*[pi*r²]+[2*pi*r*h]

then

[surface area]=2*[pi*2²]+[2*pi*2*6.5]=[ 25.13 ]+[ 81.68 ]=106.81 in²

the answer is 106.8 in²

Solve 6/×-3 =x/3
Eduardwww [97]

Answer:

X = -3. non-extraneous

Step-by-step explanation:

The given equation is \frac{6}{x-3} =\frac{x}{3}

We cross multiply  to get:

6*3=x(x-3)

Expand and multiply.

18=x^2-3x

x^2-3x-18=0

We factor to obtain:

(x-6)(x+3)=0

x=-3,x=6

Checking for extraneous solutions

Substitute x=-3 \frac{6}{-3-3} =\frac{-3}{3}

\frac{6}{-6} =\frac{-3}{3}

-1=-1

1=1.....Non-extraneous

Checking for x=6

\frac{6}{6-3} =\frac{6}{3}

\frac{6}{3} =\frac{6}{3}

2=2....Non-extraneous
