Answer:

60

Step-by-step explanation:

We know that LMO = 90

2x+4x = 90

6x = 90

Divide by 6

6x/6 = 90/6

x = 15

We want to find LMN = 4x = 4*15 = 60

Solve x – 7 > –8.
IgorC [24]
Question 1.

x - 7 > - 8

Adding 7 to both sides, we get:

x - 7 + 7 > - 8 + 7

x > -1

Thus the answer to the inequality is option Fourth.

Question 2.

A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:

x is greater than 66

x > 66

So, option 1st gives the correct answer.


Question 3.

The tiles are square shaped and area of a square can be calculated as the square of its Length.

Area of square = (Length)²

If we are given the Area, we can find the length as:

Length = \sqrt{Area}

For Tile A, the length will be:

Length= \sqrt{9}=3  
So length is a Rational number

For Tile B, the length will be:

Length= \sqrt{25}=5  
So length is a Rational number

For Tile C, the length will be:

Length= \sqrt{34}  
So, Length is not Rational.

For Tile D, the length will be:

Length= \sqrt{76}  
Length is not Rational

Thus, the lengths of Tile A and Tile B are rational only.

Therefore, the correct answer is 1st option

Zigmanuir [339]

Answer:

C


Step-by-step explanation:


<u>Job A:</u>

  • Bonus of $1500
  • $120 per day for d days is 120 multiplied by d. Which is 120d
  • Total Payment = 1500+120d

<u>Job B:</u>

  • Bonus of $2500
  • $110 per day for d days is 110 multiplied by d. Which is 110d
  • Total Payment = 2500+110d

Solving these 2 equations for d would tell us after how many days both job would pay the same. Answer choice C is correct.
