Answer:
x = 0
y = -2
Step-by-step explanation:
-5x + y = -2
x = 0
y = -2
-3x + 6y = -12
x = 0
y = -2
Answer:
x = 6
<u><em>Sorry if this answer is not correct, if it is or is not, please tell me in the comments!</em></u>
Step-by-step explanation:
All of the angles add up to 180 degrees (since it is a triangle), so
(11x - 3) + (7x + 5) + (13x - 8) = 180
Then, combine the like terms.
31x - 6 = 180
Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.
31x = 186
Then divide by 31.
x = 6
(Feel free to replace x with 6 back in the previous equation to double check it!)
Answer:
5*2+1/2*-2
11/2*-2
-11
Step-by-step explanation:
The <em>approximate increase</em> in Area of the parking lot is about 133%
Area of a rectangle = Length × width
<u>Initial Area of parking lot</u> :
- 75 feets × 150 feets = 11250 ft²
<u>New Area of parking lot</u> :
Width = 75 + 100 = 175 feets
Length = 150 feets
Area = 175 × 150 = 26250 ft²
<u>Percentage increase in </u><u>Area</u><u> </u><u>of lot</u> :
((16250 - 11250) / initial Area) × 100%
(15000 / 11250) × 100% = 133.33%
Therefore, the <em>approximate increase</em> on area of lot is 133%
