What is the value of x?<br><br> 8x−10−4x=−12(12x−20)
madreJ [45]
What is the value of X?

Simplify:
8x - 10 - 4x =   - 12(12x - 20)


Simplify both sides:
8x - 10 - 4x =  - 12(12x -20)

8x +  - 10 +  - 4x  = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x +  - 10 +  - 4x = 144x 240

(8x +  - 4x) + ( -10) =  - 144x + 240 (Combine Like Terms:)

4x +  - 10 =  - 144x + 240

4x - 10 =  - 144x + 240

Add - 144x to both sides:

4x - 10 +  144x =   - 144x + 240 + 144x

148x - 10 = 240


Add 10 to both sides:

148x - 10 + 10 = 240 + 10

148x = 250

Divide both sides by 148

148x/148 = 250/148

x = 125/74


Answer:  x = 125/74 (Decimal: 1.689189)



Hope that helps!!!!

Dana needs 6 meters of ribbon to make bows. She has 160 centimeters of ribbon. Does Dana have enough ribbon to make bows? Explai
ozzi
No; to make a bow, you need 6 meters and 6 meters = 600 centimeters. If Dana only has 160 centimeters of ribbon, bows cannot be made because 600 cm is more than 160 cm.
