Option #1 (and the fastest):
Multiply both sides by 3 to cancel the “divided by 3” on the left side where z is.
z/3 • 3 = 5/4 •3
z = 15/4
Option #2: Cross multiply and then solve for z:
z/3 = 5/4 -> 4z=15
Then divide by 4.
4z/4 = 15/4
z = 15/4
Hey there! The answer is 30 hours!
Work: 500 - 200 = 300
15 x 20 = 300
200 + 300 = 500
Simplify ( 5 x 3-x+14)-(3 x 2-9 x + 4)= 5x3 - 3x2+8x+10
Answer:
10b+40c
Step-by-step explanation:
10(b + 4c) you have to multiply 10 by each member
10b+40c
Using the concept of correlation, it is found that a strong positive correlation is expected between these two variables.
- When two variables are direct proportional, that is, both increase together, there is a <em>strong positive correlation.</em>
In this problem, <u>the older the car</u>, the more it should have traveled, that is, the <u>higher the read on the odometer</u>, hence, there is a <em>direct proportional</em> relationship, which means that the variables have a strong positive correlation.
