5(8x - 10) - 10x + 25(8x - 10) - 10x + 2
= (40x - 50) - 10x + (200x - 250) - 10x + 2
= 40x - 50 - 10x + 200x - 250 - 10x + 2
= (grouping like terms together)
= 40x - 10x + 200x - 10x - 50 - 250 + 2
= 220x - 298
1.) 8 to the second power which is 64 - 7
64-7=56
2.) 8(5-2) Parentheses first so 5-2=3
8x3=24
3.) 14 divided by 2= 7
4.) 5-8 divided by 4
-3 divided by 4= -0.75
Hope this helps!
Answer:
9x + 36, donde x es el primer número
Step-by-step explanation:
Sea "x" un número cualquiera, el consecutivo o sucesor, corresponde al número que va después, se representa como: (x + 1)
Primer número: x
Segundo número: x + 1
Tercer número: x + 2
Cuarto número: x + 3
Quinto número: x + 4
6th número: x + 5
Séptimo número: x + 6
Octavo número: x + 7
Noveno número: x + 8
La suma de 9 números consecutivos, es:
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7) + (x + 8)
9x + 36
