Virty [35]

Answer:

4

Step-by-step explanation:

use the Pythagoras' theorem

formula for an ABC triangle( right angled)

AB is height

BC is hypotenuse

CA is length

$BC^{2}$ = $AB^{2}$ + $CA^{2}$

in your case

AB is 7

BC is 8

CA is unknown so we write x

$8^{2}$ = $7^{2}$ + $x^{2}$

64=49+ $x^{2}$

64-49= $x^{2}$

15= $x^{2}$

$\sqrt{15}$ =x

3.87=x

Answer:

x = 3/4

Step-by-step explanation:

Step 1: Write equation

5x - 2(x + 1) = 1/4

Step 2: Solve for <em>x</em>

<u>Distribute -2:</u> 5x - 2x - 2 = 1/4
<u>Combine like terms:</u> 3x - 2 = 1/4
<u>Add 2 to both sides:</u> 3x = 9/4
<u>Divide both sides by 3:</u> x = 3/4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

5(3/4) - 2(3/4 + 1) = 1/4

15/4 - 2(7/4) = 1/4

15/4 - 14/4 = 1/4

1/4 = 1/4
