The sum of 5 consecutive numbers is 200. What is the smallest number?​
Vikentia [17]

Answer:

Hey!

Your answer is 44!

Step-by-step explanation:

Here's how...

x+(x+2)+(x+4)+(x+6)+(x+8)=200

5x+20=200  (minus 20 on both sides to get 5x by itself)

5x=180  (divide both sides by 5 to get just x)

x=36

5th number - x+8=36+8=44 (simple substitution and addition)

I HOPE THIS HELPS!

we are given the expression (4e) ^x and is asked to derive the expression. we distribute first the equations resulting to 4^x e^x = y. using the rule of products,
y = 4^x e^xy' =  4^x ln 4 e^x + 4^x e^x
The final answer is y' =  4^x ln 4 e^x + 4^x e^x
