First represent your 3 consecutive integers as follows.
X ⇒ <em>first integer</em>
X + 1 ⇒ <em>second integer</em>
X + 2 ⇒ <em>third integer</em>
<em />
Since their sum is 84, our equation reads x + (x + 1) + (x + 2) = 84.
Simplifying on the left side we get 3x + 3 = 84.
Now subtract 3 from both sides to get 3x = 81.
Dividing both sides by 3, we find that <em>x = 27</em>.
Finally, make sure you list all your answers.
If <em>x </em>is 27 then <em>x </em>+ 1 is 28 and <em>x </em>+ 2 is 29.

Given:
m∠R = 90°
m∠Q = 6°
PQ = 2.2 ft
RP = x
To find:
The length of RP.
Solution:
Using basic trigonometric formula:
Multiply by 2.2 on both sides.
(nearest tenth)
The length of RP is 0.2 feet.
Answer: score if the sixth pupil is 90
Step-by-step explanation:
Mean mark-75.5
6pupil
83+73+71+67+69+x= 75.5
363+x=75.5×6
×=453-363
×=90
