Answer:
x= -7
Step-by-step explanation:
1/2(4-6x)=23
Take1/2 of the numbers in the (). It will be 2-3x.
2-3x=23 subtract 2 from both sides to get x by itself
-3x=21 now divide the 21 by -3
x= -7
Answer: D) The balloon
Explanation:
Ignore the "above sea level" and "below sea level" portions. Focus purely on the numbers themselves. The largest value is the furthest away from sea level. The smallest value is closest to sea level.
Therefore, the balloon is furthest from sea level because 27 is the largest of the four values (5, 12, 18, 27).
<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>
<em><u>Solution:</u></em>
The given pyramid has 3 lateral triangular side
The figure is attached below
Base of triangle = 12 unit
<em><u>Find the perpendicular</u></em>
By Pythagoras theorem
Therefore,
<em><u>Find the lateral surface area of 1 triangle</u></em>
<em><u>Thus, lateral surface area of 3 triangle is:</u></em>
3 x 48 = 144
Thus lateral area for the pyramid with the equilateral base is 144 square units
