B. Sandwich costs $7.70 and the soda costs $2.20
Complete the square by adding the square of half of four to both sides (4)
x^2+y^2-4y+4=4
x^2+(y-2)^2=4
Answer:
15
Step-by-step explanation:
the pattern is like this
start with 1 then add 2 equals 3
start with 3 then add 3 equals 6
so 6 add 4 equals to 10
and the 5th term will be 10 add 5
equals to 15
Answer:
The number you are looking for is n < -2.333...
Step-by-step explanation:
Here is the modeled equation for this problem:
3n - 4 < -11.
Add 4 to both sides to isolate 3n.
3n - 4 + 4 < -11 + 4.
3n < -7.
Divide 3 to both sides to get the value of n.
3n/3 < -7/3.
n < -2.333...
So n must be less than -2.333... to make the equation true. Any number equal to or greater than -2.333 will result in the equation being false.
