Answer:

12=0.005×w
the number is 2400

Step-by-step explanation:

An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...

0.5% of w is 12 . . . . English

0.005 × w = 12 . . . . . . . matches choice 1

This can be solved by multiplying by 200

200(0.005w) = 200(12)

w = 2400

The number is 2400.

Given: ∠A and ∠B are complementary angles.

Eddi Din [679]

Answer:

- For the statement $-3x=24$ , the reason is: Subtraction property of Equality

- For the statement $x=-8$ , the reason is: Division property of Equality.

- For the statement $m\angle B=-6(-8)-39$ , the reason is: Substitution property of Equality.

Step-by-step explanation:

The missing pictures are attached.

We must remember that:

- The Subtraction property of Equality states that:

$If\ a=b,\ then\ a+c=b+c$

- The Division property of Equality states that:

$If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}$

- The Substitution property of Equality states that:

$If\ a=b,\ then\ b\ can\ replace\ a$

Knowing this properties we can identify the missing reasons that correctly complete the proof.

- For the statement $-3x=24$ , the reason is:

Subtraction property of Equality

(Because it is obtained by subtracting 66 from both sides of $-3x+66=90$ )

- For the statement $x=-8$ , the reason is:

Division property of Equality

(Because it is obtained by dividing both sides of $-3x=24$ by -3)

- For the statement $m\angle B=-6(-8)-39$ , the reason is:

Substitution property of Equality

(Because it is obtained by substituting the value of "x" into $m\angle B=-6x-39$ )

What number must you add to complete the square? x2 + 22x = 9

Olegator [25]

x^2 + 22x + 121 = 9 + 121 ..............a^2 + 2ab + b^2 = (a+b)^2

(x + 11)^2 = 130

answer

you must add 121 to complete the square
