Answer:
The ladder is 10 ft long...
Answer:
x=2, y=3
Step-by-step explanation:
This is a <u>system of equations</u>.
To solve a system of equations, we use the substitution method.
We can plug in the first equation, 
, into the value for <em>x</em> in the second equation. Now, the second equation looks like this:
We simplify and solve for <em>y</em>:
→ 
→ 
→ 
Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:
→ 
→ 
Let me know if my explanation is unclear.
2 boxes for $6.00 5 Bars each is 10 bars for $6.00 or $3.00 for 5 bars
so $6.00 divided by 10 =.60 or 60 cents per bar
12 bars for $7.44 is $7.44 divided by 12 =.62 or 62 cents per bar
so the difference between 60 cents and 62 cents is
2 cent Difference
The answer is
A.

Answer:
Her first error was adding the wrong number to both sides. Instead of 4², it should be 2²
Step-by-step explanation:
When completing the square, the number that needs to be added to both sides is (b/2)²
In this problem, b is 4. So, Carly should have added 2² to both sides, but she added 4² instead.
So, her first error was adding 4² to both sides instead of 2²
