Answer:
(d) 2x +y = 8
Step-by-step explanation:
The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:
2x +y = 5 . . . . . . given equation in standard form
The other equation in a system with no solution will look like this, but will have a different constant:
2x +y = 8 . . . . . . does not intersect the given equation
_____
<em>Additional comment</em>
All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:
a: 2x -(-2x+5) = 8 ⇒ 6x -5 = 8 . . . one solution: x=13/6
b: x +2(-2x+5) = 8 ⇒ -3x +10 = 8 . . . one solution: x=2/3
c: x -2(-2x+5) = 8 ⇒ 5x -10 = 8 . . . one solution: x=18/5
d: 2x +(-2x+5) = 8 ⇒ 5 = 8 . . . no solution
• look below those are the options for y or x bc you didnt say which one we solving for.
Neither. This is because 4 does not go into 9 nor the factors so it won’t work it was tricky so be careful you might think this is perpendicular.
5(1.4)x-4=25
7x-4=25
7x=25+4
7x=29
Then divide 7 by both sides and your answer is.
X = 29/7
It’s 29 over 7
Patrick's statement is incorrect.
Explanation:
Crackers come in package of = 24
Cheese slices come in package of = 18
As given, Andy wants one cheese slice for each cracker so we will find the least common multiple of 24 and 18.
The L.C.M is 72.
So, Andy needs 72 crackers and 72 cheese slices.
Number of cracker packages needed=
Number of cheese slice packages needed=
Hence, Patrick's statement is incorrect. Andy needs 3 packages of crackers and 4 packages of cheese slices to make them even.
