The sum of three consecutive even numbers is 84. What is the smallest of the three numbers?

1 answer:

6 0

Answer: 26

Step-by-step explanation: In this problem we have 3 consecutive even numbers whose sum is 84 and it asks us to find the smallest number.

Consecutive even numbers can be represented as x, x + 2, and x + 4.

Since the sum of these is 84, our equation reads

x + (x + 2) + (x + 4) = 84.

Simplifying on the left we get 3x + 6 = 84.

Subtract 6 from both sides and we have 3x = 78.

Divide both sides by 3 and x = 26.

So our smallest number is 26.

Answer:

$q = \frac{s -4p}{4}\\$

Step-by-step explanation:

$s = 4p +4q \\ 4p +4q = s \\ 4p +4q -4p = s -4p \\ 4q = s - 4p \\ \frac{4q}{4} = \frac{s -4p}{4} \\ q = \frac{s -4p}{4}$

Sz－[32－(10z＋2)]
＝Sz－(32－10z－2)
＝Sz－(30－10z)
＝Sz－30＋10z

Answer:

The third one from left to right

Step-by-step explanation:

Just check that when x = 11

y= $-\sqrt[3]{11-3}+4=-2+4=2$

So the graph passes through the point (11,2)
