Isolate the variable y
Line a: 3y = x+6
y = 1/3x + 2
Line b: 3y = x+18
y = 1/3 x + 6
Line c: 3y = 2x+9
y = 2/3x +3
Explanation:
Lines a and b are parallel because they have the same slope of 1/3.
Four CDs must be bought to receive a gift card from an <em>online</em> store.
<h3>How to determine the least number of CDs to be bought to receive a gift card</h3>
The <em>total</em> costs are equal to the sum of the <em>shipping</em> cost and the total related to the number of <em>acquired</em> CDs (n). The number of gift cards (m) is equal to the total costs divided by <em>minimum spent</em> money, that is, $ 50. We need to solve the following inequation to find the minimum quantity of CDs:
(12 · n + 5)/50 > 1
12 · n + 5 > 50
12 · n > 45
n > 45/12
n > 3.75

B. The robot can complete 6 2/3 task in on hour
Step-by-step explanation:
The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
