Answer:
x = (270° - 9y°)/2
y = (270° - 2x°)/9
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°
The angles in the quadrilateral above are: 3y°, 6y°, 2x° and 90°
2x° + 3y° + 6y° + 90° = 360°
2x° + 9y° = 360° - 90°
2x° + 9y° = 270°
2x° = 270° - 9y°
x = (270° - 9y°)/2
2x° + 9y° = 270°
9y° = 270° - 2x°
y = (270 - 2x°)/9
The anwer to this question would be 45
Answer:
Step-by-step explanation:
we know that
The solution of the linear system of equations is the intersection point both graphs
using a graphing tool
we have
------> equation A
------> equation B
To find the solution equate the equation A and equation B
Solve for x
Find the value of y
------>
the solution is the point
see the attached figure to better understand the problem
You have to read the question, then thing out he answer and right it down
Scenario: You have a measure cup with marks for tenths of Liters and need to use 12 fl oz of water to prepare a milk.
Conversion:
12 fl oz / [ fl oz / 0.0296 Liter] = 12 fl oz * 0.0296 Liter/ fl oz = 0.3552 Liter
Then you shall measure 0.355 Liter of water which is almost the same that 12 fl oz.
