Which equation illustrates the multiplication property of equality?

1 answer:

4 0

The multiplication property of equality states that if both sides of the equation is multiplied by the same number then the sides of the equations remains equal. This can be illustrated as follows:

If A = B then A(C) = B (C)

This also can be illustrated as:

If A = B and C = D therefore AC = BD

Find x and y on triangle<br>Also the degree is 30 and the other thing is 7sqrt3

nydimaria [60]

Answer:

y =7

x =14

Step-by-step explanation:

Since this is a right triangle we can use trig functions

tan 30 = opp /adj

tan 30 = y/ 7 sqrt(3)

7 sqrt(3) tan 30 = y

7 sqrt(3) * 1/ sqrt(3) =t

7 =y

sin 30 = opp/ hyp

sin 30 = 7/x

x sin 30 =7

x = 7/ sin 30

x = 7 / 1/2

x = 14

VikaD [51]

Answer:

4/15

Step-by-step explanation:

Independent events:

P(Q and R) = P(Q)×P(R)
