The <em><u>correct answer</u></em> is:

A.Angle Addition Postulate; Subtraction Property of Equality

Explanation:

The angle addition postulate states that if you place two angles side by side, then the measure of the resulting angle will be equal to the sum of the two original angle measures. This gives us m∠PQR+m∠SQR = m∠PQS.

The next missing justification is for the step that takes 2x+18=100 to 2x=82. In order to get here, we subtract 18 from each side; the property that allows this is the subtraction property of equality.

Match each power of a power expression with its simplified expression.

Molodets [167]

Answer:

(-4^9)^2 = -4^18

(4^6)^-3 = 1/4^18

(4^0)^-9 = 4^0

(4^-3)^-3 = 4^9

Step-by-step explanation:

Here, we want to match what we have on the left with the expressions on the right.

(-4^9)^2

= -4^18

(4^6)^-3

= 4^-18 = 1/4^18 according to laws of indices

(4^0)^-9 = 4^0

(4^-3)^-3

= 4^9

Suppose there are 8 runners competing in the 400 meter race. The fastest three runners will win a ribbon. In how many ways can r

yKpoI14uk [10]

Answer:

$^8C_3=336way$

Step-by-step explanation:

From the question we are told that

Number of runners $N=8$

Distance $d=400m$

Generally the top three places can be determined mathematically as

$^8C_3$

$^8C_3=336way$

therefore the top three can be determined in 336ways
