Step-by-step explanation:
(23/5)÷(-33/4)
multiply the first by the second reverse
23/5×4/-33
multiply the numerator between them and the denomination between them
92/-165
-0.558
Answer:
b and d
Step-by-step explanation:
they both have b
The equation to be solved is: 3 [ 2 ^ (2t - 5) ] - 4 = 10
The steps are:
1) transpose - 4=> 3 [ 2^ (2t - 5) ] = 10 + 4
2) Combine like terms => 3 [2^ (2t - 5) ] = 14
3) Divide both terms by 3 => 2^ (2t - 5) = 14 / 3
4) Take logarithms of both sides => (2t - 5) log (2) = log (14/3)
5) Divide both sides by log (2) =>
log (14/3)
2t - 5 = -------------------
log (2)
6) transpose - 5+>
log (14/3)
2t = ------------------- + 5 = 2.22 + 5
log (2)
2t = 7.22
7) divide both sides by 2 => t = 7.22 / 2 = 3.61
Answer:
Step-by-step explanation:
s + t = 544
t = 3s
substitution:
s + 3s = 544
s = 136
t = 3s = 408
Sam has 136 pieces. Todd has 408 pieces.
