1st find out how much the tip was:
88.50 - 75.00 = 13.50
Now find the percentage 13.5 is of 75
13.5/75 x 100 = 18% (C)
Answer:
D. An inequality models the situation better, because y could be a range of values extending into the negative direction on the number line.
Step-by-step explanation:
Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}
Isolate the k. Note the equal sign. What you do to one side, you do to the other.
First, subtract 2m from both sides
8k + 2m (-2m) = 3m (-2m) + 4
8k = m + 4
Next, divide 8 from both sides
(8k)/8 = (m + 4)/8
k = (m + 4)/8
k = m/8 + 1/2
k = m/8 + 1/2 is your answer
hope this helps
