If the area of a rectangle = LxW

Your answer would be (5y-6) (2y+10)

Your answer would be (5y-6) (2y+10)

Question

The denominator of a fraction is four more than the numerator. If both numerator and denominator are increased by eight, simplified result is 5/6. Find the original fraction (do not simplify )

Solution 1

Numerator=x

denominator=(x+4)

The original fraction would be:Â x/(x+4)

We can suggest the following equation:

**(x+8)/[(x+4)+8]=5/6**

(x+8)/(x+12)=5/6

6(x+8)=5(x+12)

6x+48=5x+60

6x-5x=60-48

x=12

The original fraction would be: x/(x+4)=12/(12+4)=12/16

**answer: the original fraction would be: 12/16**

denominator=(x+4)

The original fraction would be:Â x/(x+4)

We can suggest the following equation:

(x+8)/(x+12)=5/6

6(x+8)=5(x+12)

6x+48=5x+60

6x-5x=60-48

x=12

The original fraction would be: x/(x+4)=12/(12+4)=12/16

Solution 2

ANSWER: The original fraction is 2/4 EXPLANATION: If the numerator and denominator (2/4) had both increased by 8 ,then it will become 10/12. However, if we simplify 10/12 into lowest terms (10/12 both of them will be divided by into 2),then it will become 5/6.

Question

1 What is the solution of the system of equations? Write your answers in the blanks 4x â€“ 2y = 10
2x + y = -3 y= -2x â€“ 3
4x â€“ 24
= 10
y = -2
2-3
4x + 4x + 6 = 10
y =
8x = 4
X=

**Answer: 7**

**Step-by-step explanation:**

Question

Explain how to get the variable alone in the equation. 3x = 24â€‹

Solution 1

**Answer:**

x = 8

**Step-by-step explanation:**

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Solution 2

**Answer:**

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

**Step-by-step explanation:**

Question

On a trip to the dump, Ralph took 72 pounds of garbage. His partner, Kyle had 66 pounds. How many pounds of garbage did they get rid of altogether?

Solution 2

What the person above me said was right ^

Question

there are 120 students in a school marching band. they march in an array with the same number of students in each row. what are the dimensions of the different arrays that the band can form?

Solution 1

**Answer:**

20 X 6

**Step-by-step explanation:**

20 X 6 = 120 I'm not smart but this is pretty easy

Question

4x - 10 > 22 or x-5 < -6
I need to know how to do this step by step..

Solution 1

**Answer:**

x > 3 or x < -1

**Step-by-step explanation:**

4x - 10 > 22

Â Â Â -10 Â Â -10

4x > 12

divide both sides by 4

x > 3

x - 5 < -6

Â Â +5 Â Â +5

x < -1

Hope this helps!!!

Solution 2

Ok so the answer is x>8 the steps would be

Calculate 4x> 22+ 10

The divide from both sides 4x>32 then the answer would be x>8

Calculate 4x> 22+ 10

The divide from both sides 4x>32 then the answer would be x>8

Solution 2

The answer would be B

Question

Subtract (8x+6)-(9x-4)

Solution 1

**Hey there!**

**First, let's simplify this:**

**8x + 6 - 9x + 4**

**-x + 10**

**Hope it helps and have a great day! If you have questions about anything else or my answer, I'll be glad to help!**

Solution 2

The answer is -x+10!

8x + 6 - 9x +4

(8x-9x) + (6+4)

-x+10

8x + 6 - 9x +4

(8x-9x) + (6+4)

-x+10

Question

Solve for x Simplify your answer x/7 > -6

Solution 1

**Answer:**

x>âˆ’42

**Step-by-step explanation:**

Multiply both sides by 7.

x>âˆ’6Ã—7

Â Simplify times 6Ã—7 Â to 42.

x>âˆ’42

Solution 2

The answer is x>-42
