Answer:

B and E

Step-by-step explanation:

A: 3 + 6 < 4 + 3 and 6 > 4

-1 > 4 is false so C is not an answer.

D: 1 + 1 < 4 + 3 and 1 > 4

1 > 4 is false so D is not an answer.

E: 2 + 8 > 4 + 3 and 8 > 4

10 > 7 and 8 > 4 are both true so E is an answer.

Luigi is an urban planner. As an independent contractor, he charges a $140 fee plus $25 per hour for

Anuta_ua [19.1K]

Answer:

Function: $y=140+25x$

Amount earned for 10 hours of work: $\$390$

Step-by-step explanation:

Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.

Based on the data given in the exercise, you can identify that:

$140 is a fixed amount.
For each hour worked on the project, Luigi charges $25. This can be expressed as: $25x$

Then, the total amount he charges for a project is the sum of $140 and $25x$ . This can be represented with the following function:

$y=140+25x$

To calculate the amount of money earned for 10 hours of work, you must substitute $x=10$ into the function and evaluate. Then:

$y=140+25(10)\\\\y=390$

HURRY WILL MARK YOU BRAINLIEST RIGHT ANSWER ONLY

Galina-37 [17]

Answer:

Step-by-step explanation:

set the two equations equal to each other then solve for n

6n + 3 = 4n + 11

2n = 8

n = 4

plug n in for both equations

6(4) + 3

24 + 3 = 27

4(4) + 11

16 + 11 = 27

27 + 27 = 54

the distance is 54
