Firlakuza [10]

Answer:

55/4

Explanation:

Let's solve your equation step-by-step.

4 /5x−8=3

Step 1: Add 8 to both sides.

4 /5x−8+8=3+8

4 /5 x = 11

Step 2: Multiply both sides by 5/4.

( 5 /4 )*( 4 /5 x)=( 5 /4 )*(11)

x=  55/4

Answer:

x=

55 /4

Hope that helps :)

See attachment. what is the length of x in the diagram below?<br> answer in rational form
Norma-Jean [14]
Hi there!
Th' following triangle is divided into 2 sub-triangles!

• In 1ˢᵗ triangle :-

tan 45° = \dfrac {b}{p}

⇒ 1 = \dfrac {5}{p}

⇒ p = 5

• In 2ⁿᵈ triangle :-

cos 30° = \dfrac {p}{h}

⇒ \dfrac {1}{2} = \dfrac {5}{x}

⇒ x = 2 × 5

⇒ x = 10

Hence,
Th required answer is 10 units.

~ Hope it helps!
