The solution to the inequality is (-4, ∞)

<h3>How to solve the inequality?</h3>

The second inequality is given as:

8 - y < 12

Subtract 8 from both sides

-y < 4

Rewrite as:

y > -4

In interval form, we have:

y = (-4, ∞)

Hence, the solution to the inequality is (-4, ∞)

Please help me solve this. 4n – 19 = 29

Mrac [35]

Answer:

Solution of the equation is : n=12

Step-by-step explanation:

Given equation:

$4n - 19 = 29$

Solving the equation for 'n'

Add '19' both sides:

$4n-19+19=29+19$

$4n=29+19\\\\4n=48$

Dividing by '4' both sides:

$\frac{4n}{4}= \frac{48}{4} \\\\n=\frac{48}{4}\\\\ n=12$

The Solution of the equation is : n=12

The three sides of a triangle are 11/3 cm , 15/4 cm and 26/9 cm . find it's perimeter .

Verizon [17]

<h3>☘︎Answer :- </h3>

$\sf\longmapsto \: \frac{371}{36}$

<h3>☘︎ Solution :- </h3>

Given : Three sides are 11/3 cm , 15/4 cm and 26/9 cm
To find : perimeter of the triangle

Perimeter of a triangle = Sum of the length of the three sides

perimeter of the given triangle = 11/3 + 15/4 + 26/9

Make the denominator same by taking the LCM of the denominators .

( LCM of 3 , 4 and 9 is 36 )

$\sf\longmapsto \: \frac{132 \: + \: 135 \: + \: 104}{36} \: \: \:$

$\sf\longmapsto \: \frac{371}{36} \: cm \:$

♧ Therefore, the perimeter of a triangle is 371/36 cm
