y = x - 3
y = 7x + 3
Answer:
x=-1, y=-4
Step-by-step explanation:
For this question, you can replace y in one equation with the second one.
This means x-3=7x+3.
From there, you subtract x from each side, giving -3=6x+3.
Subtracting 3from each side makes it -6=6x.
Dividing both sides by 6 leaves x isolated, with a result of x=-1.
You can substitute the value of x into either equation to work out y. I'm using the first one, as it has smaller numbers.
This equation is now y=-1-3, which can be solved for y=-4.

Answer:
-97 feet
Step-by-step explanation:
-40+-57=-97
Answer:
If Ozzie is 8 and 6 years older than McKenzie, then McKenzie is 2 years old. So if Theo is 3 times older than McKenzie, then Theo is 6 years old.
Theo's age is calculated by multiplying McKenzie's age by 3. Given that McKenzie is 2 years old (Ozzie's age minus 6), so Theo is 6 years old.
The problem requires the application of basic arithmetic operations, specifically addition and multiplication, to solve an age problem. We know that Ozzie is 8 years old. Since Ozzie is 6 years older than McKenzie, we subtract 6 from Ozzie's age to get McKenzie's age, which is 2. Theo is 3 times older than McKenzie. Thus, to get Theo's age, we multiply McKenzie's age (2) by 3, which results in 6 years old.

The number of guests that will be served ice cream is 26 guests and there will be no ice cream left.
The total number of ice cream purchased by Yasmine at her party is:
If each guest gets served with 3/4 pints, then the number of guests that will receive the shared amount of pints is:
∴
The number of guests that can be served ice cream now is:
= 26 guests
Therefore, we can conclude that the number of guests that will be served ice cream is 26 guests and there will be no ice cream left.
