Witch expression is equivalent to 1/5(150x - 80y + 50 - 50x- 25y + 20)?
1 answer:
Answer:
20x - 21y + 14
Step-by-step explanation:
1/5(150x - 80y + 50 - 50x- 25y + 20)
Step 1 - Distribute
1/5 • 150x = 30x
1/5 • (-80y) = -16y
1/5 • 50 = 10
1/5 • (-50x) = -10x
1/5 • (-25y) = -5y
1/5 • 20 = 4
Step 2 - Combine Variables
30x - 10x = 20x
-16y - 5y = -21y
10 + 4 = 14
Step 3 - Arrange the Set of Numbers
20x - 21y + 14
<em>This</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>simplified</em><em> </em><em>expression</em><em>,</em><em> </em><em>I</em><em> </em><em>know </em><em>it</em><em> </em><em>is</em><em> </em><em>correct</em><em>,</em><em> </em><em>I </em><em>doubled</em><em> </em><em>checked </em><em>on</em><em> </em><em>my</em><em> </em><em>expression</em><em> </em><em>calculator</em><em>.</em>
