Answer:
A
Step-by-step explanation:
in option B, you are adding the 3 pound plastic box to each cardboard box
in option A, you have 5 separate carboard packages, and one 3 pound plastic box
This [option a] is the diagram that matches the scenario given.
Think of the x's as normal numbers. Let's say the weight of each "x" is 1. [it's not I'm aware that this question is different]
if you have 5 x's, you have
1 1 1 1 1 3
<em>not </em>1+3 ; 1+3 ; 1+3 ; 1+3 ; 1+3
you would only have this if you were to add a 3 pound plastic box to each individual package

Answer:
Step-by-step explanation:
2( N+ 17) = 3 (N +7)
2N+ 34= ·3N+ 21
N= 13
D= N+8 = 13+8 = 21
Fraction is 
When Im using N is equal to numerator and D for denominator, in order to get the fraction we substitute and the results combine in the fraction like this 
if you are driving 40 miles per hour
1 hour = 40 miles
60-40 = 20 miles left
20/40 = 0.5
1+0.5 = 1.5 total hours
-2x^2 + 5x -3 =0
Find the discriminate:
In the given formula a = -2, b = 5 and c = -3
The discriminate is found using the formula b^2 - 4(ac)
Replace the letters with their values:
5^2 - 4(-2*-3)
25 - 4*6
25-24 = 1
When the discriminate is greater than or equal to 0, there are two real solutions.
The answer is c) 2
