Answer:

124

Step-by-step explanation:

Multiply 60 by 132. You get 7920.

Now multiply 8 by 8. You get 64.

Divide 7920 by 64. You get 123.75.

SInce the question asks for <em>whole tiles</em> we can't buy 0.75 of a tile, so she could just get one more to fill in that 0.75. That would be 124.

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

When you subtract one negative integer from another, will your answer be greater than or less than the integer you started with?
SVEN [57.7K]
So say for example u have -7 - (-5), think of subtracting integers as adding the opposite, so ur adding the opposite of -5, the opposite of -5 is 5, so ur adding -7 and 5= -2
another one: -15 - (-18)
again, adding the opposite. -15 plus positive 18= 3
