Answer:
7500 meters
Step-by-step explanation:
Isabella walked 2 × 2.5 km = 5 km. Together, they walked ...
2.5 km + 5 km = 7.5 km = 7.5×1000 m = 7500 m
Cole and Isabella walked 7500 meters altogether.
_____
"kilo-" is a prefix meaning "one thousand". So one kilometer is 1000 meters. Then 7.5 kilometers is 7.5 times 1000 meters, or 7500 meters.
Answer: y= -x-5
Step 1: Determine which equation to change
Since we will be using the substitution method, we will need to substitute y from the bottom equation with information from the top equation. This will be the equation we change.
Step 2: Change the equation
Let’s rewrite the equation we will be working with.
3x+3y= -15
Our goal will be to get y alone on the left side. To start, let’s subtract 3x from both sides, leaving only 3y on the left side.
3x+3y= -15
3y= -3x-15
Now we need to get y completely alone by eliminating the coefficient of 3. Let’s do this by dividing each term by 3.
3y= -3x-15
y= -x-5
This is your answer. Hope this helps! Comment below for more questions.
Y-13 because it’s less than y so it’s subtracting from the y
The answer to this one would be B
