Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..
John will need 12 more weeks to save a total of $100.
5 less (-5) than 1/3 of number (n/3) is (=) 2 more than (2+) half of the number (n/2)
-5+n/3=2+n/2
add 5 to both sides
n/3=n/2+7
times 6 both sides
2n=3n+42
minus 2n both sides
0=n+42
minus 42 boh sides
-42=n
the number is -42
the number is 18
Answer:
= <em>1</em><em>4</em>
Step-by-step explanation:
So my way of doing it is to simply put 20% in decimal so
20= 0.20
Then multiply that by 70
0.20× 70 = 14%
There are probably other ways to do it but I find this way easier
1/2 x 44 is the correct answer. Since the answer to the main equation is 22.05, the closest answer to it is 1/2 x 44 which is 22.
