They have 23$ and 1$ is needed for when they get in the car. That leaves 22$. It’s 2$ per kilometer so 22/2 is 11.
They can travel 11 kilometers
Answer:
506 $
Step-by-step explanation:
Answer:
1)· 5x + 2y = 9. First we solve for y. 2y= 9 -5x. y=(9-5x)/2. Now that we have the value of y. We substitute on the original equation and resolve. 5x + 2y = 95x + 2y = 9 5x + 2(9-5x)/2 = 9 5x + 9 - 5x = 9 9 = 9
That would be x = 1
Now substitute and resolve to find y.
5(1) + 2y = 9
5 + 2y = 9
2y = 4
y = 2
So our answer x=1 and y = 2. (1,2)
Proof :
5(1) + 2(2) = 9
5+ 4 = 9
9 = 9

hoped it helped for the first one i didnt now the second one
Answer:
if x=2, y= 1
if x=5, y=-5
Step-by-step explanation:
6x+3y=15
3y=-6x+15
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
y=-2(5)+5
y=-10+5
y=-5
