11.+/- 11
Do you mean: 11d +1 = 5d+49? If so: 11d+1 = 5d+49 11d-5d = 49-1 6d = 48 d = 8
11d + 43=
c - 5d = 2 2c + d = 4 Multiply eqn 1 by 2: 2c - 10d = 4 Subtract this from eqn 2: 0c + 11d = 0 which implies that d = 0 Then, by eqn 1, c = 2
To convert 15 shillings and 11 pence (15s 11d) into US dollars, you first convert it to pounds. There are 20 shillings in a pound, so 15 shillings is 0.75 pounds (15/20), and 11 pence is 0.04583 pounds (11/240). Therefore, 15s 11d equals approximately 0.79583 pounds. As of the latest exchange rates, this is roughly equivalent to about $1.00 USD, though actual rates may vary.
To simplify the expression (6d + 8e + 11d + 8e), combine like terms. First, add the (d) terms: (6d + 11d = 17d). Then, combine the (e) terms: (8e + 8e = 16e). Therefore, the final answer is (17d + 16e).
11d 7
To simplify the expression 5d + 2(3d), you first distribute the 2 to the terms inside the parentheses, which gives you 5d + 6d. Combining like terms, you add the coefficients of the d-terms together to get 11d. Therefore, the simplified expression is 11d.
4+4 equals 8.
Very Distaurbing only one student in Grade 10 that passed to grade 11d in 2011, This school is just dieng day by day
