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
Answer:
There are 92 students who take public transportation
Step-by-step explanation:
There are 460 students who walk
20% of those who walk take public transportation
Students who take public transportation = 460*20%
Changing this to decimal form
Students who take public transportation = 460*.20 = 92
There are 92 students who take public transportation
Hope this helped! :)
The like terms in this expression are 6x^4 & 5x^4.
1 - 1/4 - 3/8
relate all these values as fractions with a common denominator of 8
8/8 - 2/8 - 3/8
(8 - 2 - 3)/8
3/8 is the amount left, so this means there is 3/8 of the playground left for SWINGS and playground equipment
