Solve the equation for y.4x - 5y = 9

A. y = -5/4x = -5/9
B. y = -4x = 9
C. y = 5/4x + 9/4
D. y = 4/5x - 9/5

Answers

Answer 1
Answer: 4x - 5y = 9 \n -5y=9-4x \n 5y= 4x-9 \n y=(4x)/(5) -(9)/(5)   \ny=(4)/(5)x -(9)/(5)

D. y = 4/5x - 9/5

What’s 48 rounded to the nearest ten

Answers

Answer:

50

Step-by-step explanation:

When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.

1. 12 = x + 3
2. b+0.6= -1
3. a+(-4)= -13
4. x+27= -12
5. a+(-1.2)= -5.5

Answers

1. 12=x+3    12-3=9  now try 9+3 that is 12 so x=9
2. b+0.6=-1   -1-0.6=-1.6   -1.6+0.6=-1  b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3
1. x = 9
2. b = -1.6
3. a= -9
4. x = -39
5. a = -4.3

Jerry wonders "how many $10 bills are equal to a $1,000 bill?

Answers

100 $10 bills are equal to a $1,000 bill.

To determine how many $10 bills are equal to a $1,000 bill, you need to divide the value of the $1,000 bill by the value of each $10 bill.

Value of $1,000 bill = $1000

Value of each $10 bill = $10

Number of $10 bills = Value of $1,000 bill / Value of each $10 bill

Number of $10 bills = $1000 / $10

Number of $10 bills = 100

So, 100 $10 bills are equal to a $1,000 bill.

Through which process is fertile soil renewed

Answers

Answer:

The process through which the fertile soil is renewed is called soil fertility.

Step-by-step explanation:

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

A fertile soil has the following properties :

  • The ability to supply essential plant nutrients and water in sufficient amounts which increase productivity.
  • The absence of toxic substances which may inhibit plant growth.

The following properties contribute to soil fertility in most situations:

  • Sufficient soil depth for adequate root growth and water retention;
  • Good internal drainage, allowing sufficient aeration for optimal root growth .

Hence, The process through which the fertile soil is renewed is called soil fertility.

Soil Fertility is the answer and there really is no explanation to this except it gives life back to soil that was once fertilized.
