Answer:
<h2>(-3) + 4x + 2 + 2x + 2x = 8x - 1</h2>
Step-by-step explanation:
(-3) + 4x + 2 + 2x + 2x <em>combine like terms</em>
= (4x + 2x + 2x) + (-3 + 2)
= 8x - 1
Answer:
6(y + 4) = -3(2y - 2) + 8y
6y + 24 = -6y + 6 + 8y
6y + 24 = 2y + 6
Subtract -2y on both sides
4y + 24 = 6
Subtract -24 on both sides
4y = -18
y = - 4.5
Answer:

Step-by-step explanation:
Dado
Precio de compra del artículo = 219
Precio de venta cuando el descuento dado es 25% = 219 + 0,25 * 219 = 273,75
Para otorgar un descuento del 25%, este producto debe estar marcado a un precio un 25% más alto que los precios de venta = 273,75 + 0,25 * 273,75 = 342,1875
Answer:
2500
Step-by-step explanation:
[8*(3+4-1)+2]^2
First calculate the number inside the round parenthesis as this operation as priority:
3+4-1=6
Then multiply this by 8 because now the multiplication has the highest priority:
8*6=48
Now you can add the 2 to the number you got:
48+2=50
Finally square the number obtained to get the answer:
50^2= 2500
