Answer:
x + 20 = area
Step-by-step explanation:
You need to recall the equation for a rectangle:
Width x Length = Area
So simply plug the values into this:
(0.5x+10) * 6
(0.5x * 6) + (10 * 6)
= 3x + 60
Simplified down by dividing by three:
= area
<h3>x + 20 = area</h3>

Answer:
x=-2,y=-2
Step-by-step explanation:
x+y=-4
x=-4-y--(3)
substitute (3) in (1)
5(-4-y) -3y=-4
-20-5y-3y=-4
-8y=16
y=16/-8
y=-2
substitute y in (3)
x=-4-(-2)
x=-2
Drop the egg from half way up the building. This divides the search space in half. If it breaks, start on the bottom floor and work your way up the top :) Hope it works
Answer: The 75th term is 86
Step-by-step explanation:
Since the sequence consists of all natural numbers which are neither perfect squares nor perfect cubes, we can write out the next ninety numbers starting from 2, and then ruling out the squares and cubes. We then count to the 75th number to the desired term. This is shown in the attachment below.
We can as well sum the number of squares and cubes in the range with the number of the number of the desired term i.e
Number of squares = 8 ( 4,9,16,25,36,49,64,81)
Number of cubes = 2 (8 and 27; excluding 64 which is as well a square)
Desired term = 75
So, 8+2+75 = 85.
Therefore, the 85th term counting from 2 ( i.e 86) is the 75th term of the sequence.
3/4
The easiest way to solve this is to test the numbers one by one. 2/3 is not the answer because 2/3 times 3/2 is 1, not 9/8. It is 3/4 because 3/2 times 3/4 is 9/8, 9/8 times 3/4 is 27/32, and so forth.
