Answer:
800
Step-by-step explanation:
d=2r=2·400=800
25-14=11
11+3=14
25+3=28
28 divided by 2=14
Step-by-step explanation:
X-2y=5 ; 2x-4y=10
• x - 2y = 5 • 2x -4y = 10
-2y = -x+5 -4y= -2x +10
y1 = ½x - 5/2 y2 = ½x -5/2
• => y1 = y2
½x -5/2 = ½x -5/2
the systems have no solution
• graph as attached
4500 is both divisible by 5 and 9
4500/9=500
4500/5=900
