Using the equation of best fit provided:
y=0.216x + 32.575
The slope is the number with the x, so the slope is 0.216 and the y- intercept is the number added at the end. The y intercept is 32.575
Answer: B. 5 carpenters and 4 masons. Is $2,150
Step-by-step explanation:
250 • 5 = 1,250

$2,150
Answer: 78 problems
Step-by-step explanation:
Let x = the total number of problems that Joe started with. Joe finished half of his homework questions at school. This means that he finished 1/2 × x = x/2 of the home work at school. What he has left is x - x/2 = x/2.
He completed one-third after practice. This means he completed 1/3 × x = x/3 after practice The number of problems left altogether would be total number of problems - the the sum of the amount he finished at school and the amount he completed after practice. It would be x -(x/2 + x /3) = x - 5x/6 = x/6
If he has 13 to more to finish, that means
x/6 = 13
x = 13×6 = 78 minutes
Answer:
3x+8
Step-by-step explanation:
Basically, this is just adding like terms. So, 2x+x=3x and 5+3=8. The final equation would be 3x+8.
