Answer:

C. ⇒ 2 : 4. This is because 2 may be a multiple of 1, however, 3 is not a direct multiple of 4.
Answer: slope is 1
Y-intercept= -2
Step-by-step explanation:
X y
0 -2
1 -1
We need to isolate z on one side of the equation.
First, add 3/7 to both sides of the equation (this will cancel out the -3/7):
2z < 49 + 3/7
Let's change (49+3/7) into an improper fraction:
2z < 346/7
Divide both sides by 2 to get the answer:
z < 173/7
Answer:
Try this solution, it consists of two parts (MN=8).
Step-by-step explanation:
The answer to your question is: .75 = 3x - .03
How to solve it:
x = the cost of a pack of gum twenty years ago
.75 = 3x - .03
+ .03 + .03
.78 = 3x
/ 3 / 3
.26 = x
If a pack of gum now costs 75 cents, which is 3 cents less than three times what a pack would have cost 20 years ago, then a pack of gum would have cost 26 cents.
