Equality Properties

Step-by-step explanation:

Step 1: Define equation

2(-5r + 2) = 84

Step 2: Solve for r

Divide 2 on both sides: -5r + 2 = 42
Subtract 2 on both sides: -5r = 40
Divide -5 on both sides: r = -8

Step 3: Check

Plug in r into the original equation to verify it's a solution.

Substitute in r: 2(-5(-8) + 2) = 84
Multiply: 2(40 + 2) = 84
Add: 2(42) = 84
Multiply: 84 = 84

Here we see that 84 does indeed equal 84.

∴ r = -8 is a solution of the equation.

Step 4: Define equation

264 = -8(-8 + 5x)

Step 5: Solve for x

Divide both sides by -8: -33 = -8 + 5x
Add 8 to both sides: -25 = 5x
Divide 5 on both sides: -5 = x
Rewrite: x = -5

Step 6: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 264 = -8(-8 + 5(-5))
Multiply: 264 = -8(-8 - 25)
Subtract: 264 = -8(-33)
Multiply: 264 = 264

Here we see that 264 does indeed equal 264.

∴ x = -5 is a solution of the equation.

The quadrilaterals ABCD and PQRS are similar. Find the length X of SP.

BaLLatris [955]

Answer:

$x = 3.6$

Step-by-step explanation:

Since Quadrilateral ABCD ~ PQRS, therefore:

$\frac{AB}{PQ} = \frac{BC}{QR} = \frac{CD}{RS} = \frac{DA}{SP}$

Let's find the value of x by using the ratio of two corresponding sides of both quadrilaterals. Let's use:

$\frac{CD}{RS} = \frac{DA}{SP}$

CD = 5

RS = 4.5

DA = 4

SP = x

$\frac{5}{4.5} = \frac{4}{x}$

Cross multiply

$5*x = 4.5*4$

$5x = 18$

Divide both sides by 5

$x = \frac{18}{5}$

$x = 3.6$
