Answer:
41.2
Step-by-step explanation:
(c + a = 800)5
5c + 16a = 8400
5c + 5a = 4000
Subtract
11a = 4400
a = 400
There were 400 children and 400 adults
Answer:
1) 22.4
2) 23.4
3) 24.4
4) 25.4
5) 26.4
Step-by-step explanation:
La suma de 5 números consecutivos es 122 ¿cuáles son esos números?
5 números consecutivos se pueden representar como
1) = x
2) x + 1
3) x + 2
4) x + 3
5) x + 4
Por eso:
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 122
x + x + 1 + x + 2 + x + 3 + x + 4 = 122
5x +10 = 122
5x = 122 - 10
5 veces = 112
x = 112/5
x = 22.4
5 números consecutivos se pueden representar como
1) x = 22.4
2) x + 1 = 22.4 + 1 = 23.4
3) x + 2 = 22.4 + 2 = 24.4
4) x + 3 = 22.4 + 3 = 25.4
5) x + 4 = 22.4 + 4 = 26.4
Honestly I can’t remember the last time I had to deal with arcs in school, but the answer to the second one is 63 because all triangles add up to 180 degrees and 46+71= 117. 180-117=63
