Twice the difference between 5 times a number and 6 equals 18:

2(5x-6)=18

We need to solve for x:

5x - 6 = 2(difference) = 18

The difference must equal 9.
In order for the difference to equal 9, x must equal 3.

5(3) - 6 = 2(difference) = 18

Let's solve:

15 - 6 = 2(9) = 18

Therefore, in this equation, x = 3.

Find the measure of x.<br> X<br> 55°<br> 80<br> X<br> = [ ?<br> ]<br> Round to the nearest tenth.

NARA [144]

<h3>Answer: 139.5</h3>

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(55) = 80/x

x*cos(55) = 80

x = 80/cos(55)

x = 139.4757 approximately

x = 139.5
