I NEED HELP ASAPPPP<br> In square YOLA , RL=5x+28 and RO=8x-11 find the measure of line segment RY

tresset_1 [31]

Answer:

RL=5x+28 and

RO=8X-11

diagonal of square bisect equally the side

:.5x+28=8x-11

11+28=8x-5x

39=3x

x=39/3=13

RY=RL=5x+28=5×13+28=93If the answer is 93, move to S

Identify the property used in each step of solving the inequality 3x-2>-4.

WARRIOR [948]

Addition property of equality

Division property of equality

<em><u>Solution:</u></em>

<em><u>Given inequality is:</u></em>

3x - 2 > 4

$\mathrm{Add\:}2\mathrm{\:to\:both\:sides}$

Here, Addition property of equality is used

When the same amount is added to both sides of an inequality, then the inequality is still true

3x - 2 + 2 > 4 + 2

3x > 6

$\mathrm{Divide\:both\:sides\:by\:}3$

Here, Division property of equality is used

When we divide both sides of an equation by the same nonzero number, the sides remain equal.

$\frac{3x}{3}>\frac{6}{3}\\\\x > 2$

Thus the property used in each step of solving the inequality is found
