Solve the inequality 4y + 3 > 24 + 14.
Degger [83]
Hi there!

Solving th' Inequality :-

4y + 3 > 24 + 14

=> 4y + 3 > 38

=> 4y > 38 - 3

=> 4y > 35

=> y > \dfrac {35}{4}

=> y > 8.75

Therefore, all real number y which are greater than 8.75 are the solutions of th' given Inequality.

Hence,
Solution of the following Inequality is : ( 8.75, ∞ )

Find the value of the variable 7x + 19 11x -89 60°​
I am Lyosha [343]
<h2>7x + 19 = 208</h2><h2>11x - 89 = 208</h2><h2>--------------------------------------</h2>

<u>Step-by-step explanation:</u>

let third angle be x

60° + 60° + x = 180° (Δ sum property)

x = 60°

so, this is a equilateral triangle (all Δ equal)

<h2>-----------------------------------------</h2>

in equilateral triangle --> all sides are equal

so, therefore =>>

7x + 19 = 11x - 89

19 + 89 = 11x - 7x

108 = 4x

108 ÷ 4 = x

27 = x

<h3>x = 27</h3><h2>-----------------------------------------</h2>

so variable

1.) 7x + 19

= 7(27) + 19

= 189 + 19

= 208

2.) 11x - 89

= 11(27) - 89

= 297 - 89

= 208

Y is directly proportional to x, and y =216 when x=2 find y when x=7
jek_recluse [69]
Y = kx
@ y = 216, x = 2
k = y/x = 216/2 = 108

@ x=7
y = (108)(7) = 756
