Step-by-step explanation:
A) For income, if A makes 500 per hour then B will make 1000 per hour
(you can use equation B=2A because a ratio of 1:2 means B will be making double the salary of A
1. n= 2.67
2. x= 5
3. x= 50
4. r= 13
if you get number four wrong i'm sorry ....
The equation would be X +21+ 2X +17+ 2X +17 equals 180 when solved you get X equals 25
The origin is the point (0,0) where the x and y axis intersect. To get to the point (-1,1) start at the origin, move one unit to the left and one unit up. To get to the point (1,-1.5) start at the origin and move one unit right and down one and a half. To get to the point (2, 1/4) start at the origin and move 2 units right and up one fourth of the way to 1.
The answer is
ab=a×b=12×4=48.
