Answer:
x=2
Step-by-step explanation:
5(x+2)=24-2x
5x+10=24-2x
5x-(-2x)+10=24
5x+2x=24-10
7x=14
x=14/7
x=2
Answer:
a) 0.04
b) 0.08
Step-by-step explanation:
Part a)
Divide the price of a pack by the number of stickers in a pack to get the price of one sticker.
$2/50 = $0.04/1
One stickers costs $0.04.
Part b)
Calculate 80% more than the price of one sticker.
80% in decimal form is 0.8. 80% more than the price is calculated with the factor 1.8.
($0.04)(1.8) = $0.072
Round 0.072 up because is rounded down, the profit is less than 80%.
0.072 => 0.08
Each sticker would need to be sold for $0.08.

Answer:
-3i +9j+3k
Step-by-step explanation:
Given that the vector is represented by the directed line segment with initial point A(1, −4, 1) and terminal point B(−2, 5, 4).
Position vector of A with respect to origin = (1, −4, 1)
position vector of B with respect to origin = (-2,5,4)
AB vector = OB-OA
= (-2-1, 5-(-4),4-1)
= (-3, 9, 3)
Line segment AB is (-3,9,3) or
-3i +9j+3k
Initial point is A and final point is B
