Answer:
302yrs old.... DAM
Step-by-step explanation:
2x-400=204
+400 +400
2x=604
/2 /2
x=302
Answer:
z=-3 so 2y+3(-3)=-8, 2y-9=-8, add 9 to both sides 2y=1 divide both sides by 2, y=1/2, so 3x+4(1/2)+-3=-2, 3x+2-3=-2, 3x-1=-2, add 1 to both sides, 3x=-1, divide both sides by 3, x=-1/3
2/3 = 8/12
1/4 = 4/12
You start with 8/12 and eat 4/12 so 4/12 (or one quarter) remains.
The answer is 1 19/80 or 1.2375.
Hope this helps!
300 is the original amount and 0.5 is the rate (a percent) which is deacying because it is less than 1
