5. If a = b, and b = c then a = c is the transitive property.

6. The converse is switching the order of the statement.

The answer would be If A <15, then a <10: true

7. You have RS + ST = RT

Using subtraction property solve for RS by subtracting ST from both sides to get: RS = RT-ST

8. The addition property would be adding the same thing to both sides:

So. If p=q, then p+s = q+s

9. Vertical angles are the same:

6x-22 = 4x+2

Subtract 4x from both sides:

2x-22 = 2

Add 22 to both sides:

2x = 24

Divide both sides by 2:

x = 12

What is the simplest radical form of the expression? (8x4y5)23

Komok [63]

The radical form of the expression $(8x^{4} y^{5} )^{2/ 3}$ is $4(\sqrt[3]{x^{4}y^{5} } )^{2}$

<h3>How to express an expression in radical form?</h3>

$(8x^{4} y^{5} )^{2/ 3}$

using indices law,

(yⁿ)ˣ = yⁿˣ

Therefore,

2³ = 8

Hence,

$(2^{3} x^{4} y^{5} )^{2/ 3}$ = $4(x^{4} y^{5} )^{2/ 3}$

Finally, in radical form,

$4(x^{4} y^{5} )^{2/ 3} = 4(\sqrt[3]{x^{4}y^{5} } )^{2}$

tudents are given 3 minutes for each multiple-choice question and 5 minutes for each free-response question on a test. There are

AlladinOne [14]

In this question, they gave you the system of equations. You just need to use the two of them.

We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.

$m + f = 15$
$f = 15 - m$

If we know the m form of f, we can convert the second equation and find the answer: $3m + 5f = 51$

Plug in the m value of f: $3m + 5(15 - m) = 51$

Distribute the 5: $3m + 75 - 5m = 51$

Subtract -75 from both sides: $3m - 5m= 51 - 75$

Combine like terms: $- 2m = - 24$

Divide both sides by -2: $m = 12$

So, we learned that the number of the multiple-choice questions is 12.
