The first step is to add 5 on both sides then you have 5X equals 2X +102 then you minus 2X on both sides so then you have 3X equals 102 then you divide 3X and three so you could have asked by itself and then you have 102÷3 = 34 so your answer is X equals 34

Answer: x=34

Step-by-step explanation:

1. You subtract 2x from 5x on the other side to get rid of the 2x leaving you with 3x.

2. Then you add 5 to 97 to get rid of the -5, giving you 102 on the opposite side.

3. divide 102 by 3x giving you 34.

5x-5=2x+97

-2x -2x

3x-5=97 <u><em>X=102</em></u>

+5 +5

3x=102

x/3 102/3

I hope this helps you

5=7x+0.1+10x-0.2

17x=5.1

x=5.1/17

x=3/10

What is the measure of EAB in circle F?<br> 72°<br> 92°<br> 148°<br> 200°

Arada [10]

We have been given a diagram. We are asked find the measure of arc EAB.

First of all, we will find the measure of arcs ED and CB using our given information.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.

$\widehat{EDC}=2\times m\angle EBC$

$\widehat{EDC}=2\times 80^{\circ}$

$\widehat{EDC}=160^{\circ}$

Similarly, we will find the measure of arc DCB.

$\widehat{DCB}=2\times m\angle DEB$

$\widehat{DCB}=2\times 70^{\circ}$

$\widehat{DCB}=140^{\circ}$

$\widehat{ED}=\widehat{EDC}-\wdiehat{DC}$

$\widehat{ED}=160^{\circ}-88^{\circ}$

$\widehat{ED}=72^{\circ}$

$\widehat{ED}+\widehat{DCB}+\widehat{EAB}=360^{\circ}$

$72^{\circ}+140^{\circ}+\widehat{EAB}=360^{\circ}$

$212^{\circ}+\widehat{EAB}=360^{\circ}$

$\widehat{EAB}=360^{\circ}-212^{\circ}$

$\widehat{EAB}=148^{\circ}$

Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
