Step-by-step explanation:
use formula
(-b+√b2-4ac)/2a
a=3, b=2 , c=5
(-2+√4-4×3×5)/2×3
(-2+√-56)/6
(-2+2√-14)/6
(-2 +2√14i)/6
No. 1 = x
No. 2 = 2x+7
No. 3 = x-12
Answer:
x+(2x+7)+(x-12) = 131
From there you solve to get the numbers:
34, 75 and 22
Answer:
8
Step-by-step explanation:
Jeremiah bought x toy sets for $20 each and then a video game for $60. Jeremiah spent a total of $220. How may toy sets did he buy?
To find our answer, we can solve the equation:
20x + 60 = 220
-60 -60
20x = 160
/20 /20
x = 8
Jeremiah bought 8 toy sets!
I hope this helps :)
I think it is 3200 because you divide 8000 by 5 then multiply that by 2
