Answer:
Y=2×+13
Step-by-step explanation:
2×+3=0
2×=0-3
you use 3 to divide it self =×
×=3
set them equal to their sum. which in this case is 141 then solve for x and plug it into your original equation to get your answer.
Using the Pythagorean theorem:
WY =√(5^2 + 12^2)
WY = √(25 +144)
WY = √169
WY = 13 mm
So since a percent is out of 100 you would put 11/20 and right an equal sign next to that and the bottom fraction would be x/100. Then you would find the relationship between 100 and 20. 20 times 5 is 100 so then 11 times 5 is 55. 55% is your answer
