The answer would be 30-10 and if you dove it all the way it would be 20.
Hope this helps.
Answer:
12.5 mph
Step-by-step explanation:
50 miles / 4 hours=
25 miles / 2 hours=
12.5 mph
While it's pretty obvious to most of us that
-13x=90-2y
-6x=48-2y
is a system of linear equations, it'd be well to include that info plus the instructions "solve this system of linear equations."
Subtract the 2nd equation from the first:
-13x=90-2y
+6x=-48+2y
-----------------------
-7x = 42. Then x = -42/7, or x = 6.
Now subst. 6 for x in either one of the given equations. Suppose we use the 2nd equation:
-6x=48-2y
Then -6(6)=48-2y, or -36 = 48 - 2y, or 2y = 48+ 36 = 84. Then y = 42.
The solution is (6, 42).
Answer:
Reflect over y axis and go 7 units down.
Step-by-step explanation:
It will match the triangles.
360/60 = 6
6 degrees every second
6*20 = 120 degrees
120 degrees after 20 seconds
6 * 45 = 270
270 degrees after 45 seconds
