Answer:
-x -y = 5
Step-by-step explanation:
the Answer will be 5
W= 6/5L L=12 inches
W=14.4 inches
perimeter of rectangle = 2(W+L)
=2(14.4+12)
=2(26.4)
=52.8 inches
Your answer should be D, 163, hope this helps! :D
Answer:
12
Step-by-step explanation:
It is worthwhile memorizing the ratios of legs in a 30°–60°–90° triangle. Shortest to longest, the ratios are ...
1 : √3 : 2
Then the sides marked will have the ratio ...
6 : x = 1 : 2 = 6 : 12
x = 12
_____
You can also get there using trigonometry.
cos(60°) = 6/x
x = 60/cos(60° = 60/0.5
x = 12
Step-by-step explanation:
his father's age= 4x
his mother's age= 4x- 7
his age= x
x+4x+4x-7=101
x+ 4x+ 4x= 101+ 7
9x= 108
=
x= 12
