Answer:

LM = 28 units

Step-by-step explanation:

Length of segment KL = (4x + 7) units

Length of segment LM = (5x - 12) units

Length of LM = 67 units

Since length of KM = length of KL + length of LM

By substituting the given values in the expression,

67 = (4x + 7) + (5x - 12)

67 = (4x + 5x) + (7 - 12)

67 = 9x - 5

9x = 67 + 5

x = $\frac{72}{9}$

x = 8

Therefore,

LM = (5x - 12)

= (5×8) - 12

= 40 - 12

= 28

Length of segment KM is 28 units.

Which expression is equivalent to 144 superscript three-halves?

IrinaK [193]

Using the law of indices the equivalent expression of $144^{\frac{3}{2} }$ is 1728

<h3>How to find equivalent expression?</h3>

The equivalent expression of $144^{\frac{3}{2} }$ can be express as follows:

Using the law of indices,

$(a^{b} )^{c} = a^{bc}$

Applying this laws,

$144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} }$

Hence,

$144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} } = 12^{3}$

Finally,

12³ = 1728

A. (1.34)(5.46) = (1.76)(x)

Alja [10]

We are given an equation with an unknown variable x. We can find the value of x by dividing both sides by 1.76, as this will leave only x on the right hand side of the equation and its value on the left hand side, as shown below:

$(1.34)(5.46)=1.76(x) \\ \\ 
 \frac{(1.34)(5.46)}{1.76} = \frac{1.76(x)}{1.76} \\ \\ 
 \frac{(1.34)(5.46)}{1.76} =x \\ \\ 
4.16=x$

Thus solving the given equation, we get x =4.16, rounded of to nearest hundredth.

If 97 of 200 is 100% then how much of 200 is 112%

pickupchik [31]

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 112 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 112 is 100%, so we can write it down as 112=100%.
4. We know, that x is 200% of the output value, so we can write it down as x=200%.
5. Now we have two simple equations:
1) 112=100%
2) x=200%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
112/x=100%/200%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 200% of 112

112/x=100/200
(112/x)*x=(100/200)*x - we multiply both sides of the equation by x
112=0.5*x - we divide both sides of the equation by (0.5) to get x
112/0.5=x
224=x
x=224

now we have:
200% of 112=224
