Answer:

D. Division property of Equality

Yes, this is correct because a division by -3/8 was applied and that's why it turned the solution into multiplication by using its reciprocal (-8/3).

Step-by-step explanation:

1. Let's find out the property applied to solve the equation:

-3/8x = 48

-3/8 * (-8/3)x = 48 * (-8/3)

x = -128

A. Addition property of Equality

No, this is not correct because no addition was used.

B. Subtraction property of Equality

No, this is not correct because no subtraction was applied.

C. Multiplication property of Equality

No, this is not correct because in case it was applied, it should have being done this way:

-3/8x = 48

-3/8 * (-3/8)x = 48 * (-3/8)

9x/64 = -144/8

D. Division property of Equality

Yes, this is correct because a division by -3/8 was applied and that's why it turned the solution into multiplication by using its reciprocal (-8/3).

Write 0.003 as the product of a whole number and a power of 10

Arte-miy333 [17]

3 × $10^{-3}$

expressing as a whole number, using the digits available, we obtain

Now consider the position of the decimal point in the original 0.003

To get it back to where it should be we require to move the decimal point 3 places to the left , denoted by a negative exponent

0.003 = 3 × $10^{-3}$

What is the solution of the given inequality? -4(2x+1)<_3(x-5)

soldi70 [24.7K]

Answer:

x ≥ 1

Step-by-step explanation:

Solve the inequality by solving for x.

Solve:

-4(2x + 1) ≤ 3(x - 5)

Use the distributive property.

-8x - 4 ≤ 3(x - 5)

-8x - 4 ≤ 3x - 15

Subtract 3x from both sides.

-11x - 4 ≤ -15

Add 4 to both sides.

-11x ≤ -11

Divide both sides by -11, also flip the inequality since you're dividing by a negative number.

x ≥ 1

Your final answer would be x ≥ 1

At the start of the diet keirin weighted 14 stone 13 pounds three months later he weighted 13 stone 10 pounds there are 14 pound

WINSTONCH [101]

Answer:

The amount of weight he has lost in 3 months is 1.215 stone or 1 stone 3 pounds

Step-by-step explanation:

From the above question, we are to calculate the amount of weight he has lost in three months

1 stone = 14 pounds

Let's convert all the weight lost to stone

At the start of the diet keirin weighted 14 stone 13 pounds

14 pounds = 1 stone

13 pounds = x

Cross Multiply

14x = 13

x = 13/14

x = 0.9285714286 stone

Approximately = 0.929 stone

Hence:

14 stone 13 pounds = 14 + 0.929 = 14.929 stone

Three months later he weighted 13 stone 10 pounds

14 pounds = 1 stone

10pounds = x

Cross Multiply

14x = 10

x = 10/14

x = 0.7142857143 stone

Approximately = 0.714 stone

Hence:

13 stone 10 pounds = 13 + 0.714 = 13.714 stone

The amount of weight he has lost is calculated as:

14.929 stone - 13.714 stone = 1.215 stone or 1 stone 3 pounds

111=13, 113=35, 115=57, 117=?

Elden [556K]

In the pattern, the values are increasing by 22 each time so for the 117th term you take 57 + 22 = 79

So, 117= 79
