Answer:
it should be 10,000 square meters
Step-by-step explanation:
my mind
(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
<span>N + D = 55 coins (1) (N stands for nickels,
5N + 10D = 390 cents (2) D stands for dimes)
Simplify (2) by canceling the factor 5 in both sides:
N + 2D = 78 (3)
Subtract eq(1) from eq(3). You will get
D = 78 - 55 = 23.
Answer. 23 dimes and 55-23 = 32 nickels.
Check. 23*10 + 32*5 = 390 cents</span>
Well i remember doing this awhile back but your not giving very much detail but i think it’s c if I’m wrong just correct me
<u>3x + 9</u> = 3
x + 3
The answer to the problem is equal to 3.
