Answer:

MN = 25

Step-by-step explanation:

If LN=45, then the addition of both quantities will be 45.

LN = 3x + 2 + x + 19

3x + 2 + x + 19 = 45

4x + 21 = 45

4x = 45 - 21 = 24

x = 6

Now that we found the value of "x", we can find the lenght of MN

MN = x + 19

MN = 6 + 19

MN = 25

Hope it was helpful ;)

Answer: MN = 25

Step-by-step explanation:

Since the length is already given we just add the equations equal to it.

45 =  3x + 2 + x + 19  Combine like terms

45 = 4x + 21               Subtract 21 from both sides

24 = 4x                       Divide by 4

x = 6

Now we plug x into the equation needed.

X + 19

6 + 19 = 25

Step-by-step explanation:

The easiest way to remember how to do this problem is to average the x-coordinates and average the y-coordinates.

So, in your problem (-3 + 12)/2 = 9/2   and  (-5 + 12)/2 = 7/2

x=120 (x-60)=60

Step-by-step explanation:

Because the unlabeled angle and right angle are parallel we can assume that the unlabeled angle will be 90 degrees.

90+90+x+(x-60)=360

120+2x=360

-120 -120

2x=240

x=120

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

Answers

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

Answer:

Step-by-step explanation:

Add 7 to both sides

9x = 0

Then divide by 9 both sides to get x by itself

x = 0

Elijah played 98 consecutive games of soccer without being taken off the field. Then, after a single game on the sidelines, he played another string of consecutive games, although this string was 50% shorter. How many consecutive games was that?

Answers

Answer:

If the game will start at 11:00 A.M., but the players must arrive at the field three-quarters of an hour early to warm up, it refers to 8:45 a.m. Why? If we start to count in 11 backward and start to trace the three-quarters, it shows that 10:45, 9:45, and 8:45 are the three-quarters. So Hamid statement that he has to be at the field at 9:45 A.M is not correct.

The sum of three numbers is 107 . The first number is 8 less than the third . The second number is 3 times the third . What are the numbers ?

Answers

First number = x
Third number = x - 7
Second number = 2(x - 7)
x + 2(x - 7) + x - 7 = 107
x + 2x - 14 + x - 7 = 107
Collect like terms.
4x - 21 = 107
4x = 128
x = 32
First number = 32
Second number = 50
Third number = 25
Total = 107.

Answer:

(x - 8) + 3x + x = 107

x - 8 + 3x + x = 107

5x - 8 = 107

5x = 115

x = 23, SO...

The first number is 23-8, which is 15

The second number is 3 x 23, which is 69

The third number is 23

15 + 69 + 23 = 107 CHECK!

A rectangular garden is to cover 416 square feet of area. If the width is 10

feet less than the length, find the dimensions of the garden.

Answers

Answer:

Length = 26 feet, Width = 16 feet

Step-by-step explanation:

Let the length be l.

Width b = l-10

The area of a rectangular garden, A = 416 feet²

We need to find the dimensions of the garden. The area of a rectangular shaped object is given by :

[tex]A=lb\\\\l(l-10)=416\\\\l^2-10l-416=0\\\\l=26\ ft,-16\ ft[/tex]

Neglecting the negative value, the length of the garden is 26 feet and the width is 12-10 = 16 feet.
