Answer:

0.125 < x < 0.18.... WHICH YOUR BEST ANSWER IS PROBABLY D

Step-by-step explanation:

The options are not complete

Given

x = 18%

x> 1/8

Required'

Determine the range that makes x an inequality

We have:

x< 18% and x > 1/8

Convert all to decimal

x < 0.18 and  x> 0.125

This can be rewritten as:

x< 0.18 and 0.125 < x

0.125 < x < 0.18

SO YOUR BEST BET IS ANSWER D

Answer: 1/4

Step 1: Convert to percents.

3/4 = 75%

1/2 = 50%

Step 2: Subtract.

75% - 50% = 25%

Step 3: Convert to fraction.

25% = 1/4

Hope this helps!

Answer:

23/72 is the answer in simplest form

Step-by-step explanation:

Answer:

x > -22/7

Step-by-step explanation:

To find out which inequality is is equivalent, you solve for x.

-4(x+7) < 3(x-2): distribute variables

-4x-28 < 3x-6: Add 6 to both sided

-4x-22 < 3x: add 4x to both sides

-22 < 7x: divide by 7

-22/7 < x: you can switch sides if prefered but you have to switch sign too

x > -22/7

Answer:

ok

Step-by-step explanation:

1+1=2

then times it by 2

they are the same length

Answer:

The answer is 20 hours

Step-by-step explanation:

This is becuase 1280 divided by 64 equals 20.  There are no unit coversions.

In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Given that,
A car travels a distance of 1280 meters at an average speed of 64 kilometers per hour.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Time  = distance/speed
Time. t = 1.280 / 64

t = 0.02 hours

Thus, In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

10 = 10

Step-by-step explanation:

x + 3 = 10

Substitute 7 in for x

7 + 3 = 10

Add

10 = 10

Answer: no wrong cause in order to get 7 as x=7 you need to do x+2=10 cause x+3=4 so that would be wrong

Step-by-step explanation: x=3=10 x=7

x+3=4x=10

4x-10=6

Answer:

Answer One: 3 miles. Answer Two:  105.

Step-by-step explanation:

Answer One: Due to it being 7/10s we have to get 2/5 to a tenth. We multiply 2 and 5 by 2 to get 4/10s subtract 7/10s to 4/10s getting 3/10s which is equal to 45 minutes. So that means 4/10s is equal to an hour. The change in height is 3/10s. Answer Two: It begins it's flight at 7/10s above ground so after 45 minutes it's now at 4/10s due to 45 minutes equaling 3/10s, you need another hour to reach the ground so add 45 minutes to 60 minutes to get 105.

Answer:

x^2 = 1 / x ^ -2

x^4 ÷ x^3 = x

(x^2)^2 = x^4

x^3 × x^3 × x^3 = x ^ 9

Step-by-step explanation:

By using law on indices the equivalent expression of x² = 1/x⁻²,x⁴ ÷ x³ = x,(x²)² = x⁴ and x³ × x³ × x³ = x⁹.

Index (indices) in Maths is the power or exponent which is raised to a number or a variable.

For example 5³ = 5²5 here we break 5³ into 5² and 5 so it is called the law of indices.

As per the given expression,

x² now by the law of indices that aˣ=1/a⁻ˣ.

Therefore,x² = 1/x⁻²

x⁴ ÷ x³ = x(x³)/x³=x

Now,

(x²)² the law of indices that (a²)³=a²ˣ³=a⁶

Therefore,(x²)² = x⁴

Now,

x³ × x³ × x³ the law of indices that aˣ × aˣ × aˣ =a⁽ˣ⁺ˣ⁺ˣ⁾

Therefore,x³ × x³ × x³ = x⁹

Hence "By using law on indices the equivalent expression of x² = 1/x⁻²,x⁴ ÷ x³ = x,(x²)² = x⁴ and x³ × x³ × x³ = x⁹".
