Answer:
Step-by-step explanation:
Let chocolate bar cost be c and blow pop cost be b
<u>Then we have equations:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>Multiply the first equation by 13 and the second one by 8 and subtract:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Chocolate bar costs $2.65
Answer:
i think it is 125
Step-by-step explanation:
Solución:
Después de simplificar esta ecuación, el solución es 6 x 1 o 6.
Explicación:
Para encontrar la respuesta, debemos simplificar los términos entre paréntesis.
6 x (8 + 10 - 12 + 15 - 20)
6 x (18 - 12 + 15 - 20)
6 x (6 + 15 - 20)
6 x (21 - 20)
6 x (1)
Luego te quedas con 6 x 1, o 6.
Answer:
Places in binary coding
1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 - 2048
2483 - 2048 = 435 there is 1 in the 2048 position
435 - 256 = 179 there is 1 in the 256 position
179 - 128 = 51 there is 1 in the 128 position
51 - 32 = 19 there is 1 in the 32 position
19 - 16 = 3 there is 1 in the 16 position
3 - 2 = 1 there is 1 in the 2 position
1 - 1 = 0 there is 1 in the 1 position
10011011 0011 would be the binary result
Check:
2048 + 0 + 0 + 256 + 128 + 0 + 32 + 16 + 0 + 0 + 2 + 1 = 2483
