Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
Answer:
Step-by-step explanation:
Y = 1/5 x + 14 where b = 7
Result:
x + 70 = 5 Y
Geometric figure:
line
Alternate forms:
x = 5 Y - 70
x - 5 Y + 70 = 0
Real solution:
Y = x/5 + 14
Solution:
Y = x/5 + 14
Integer solution:
x = 5 n, Y = n + 14, n element Z
Solution for the variable x:
Answer:
10
Step-by-step explanation:
There is a way to turn this into a simple equation, but I will not go through that.
So the conditions are saying the first term is 40 and for every term after that you multiply the last by .5. So to get the fifth you would multiply the fourth by .5.
We want the third, so we need to multiply the second by .5. To get the second we multiply the first by .5. since the first is 40, 40*.5=20. Then just repeat.
