First, distribute the -1

-9-12+3x

Then subtract the -9 and -12

-21 + 3x

Add 21 to both sides*

21 = 3x

Divide

x = 7

*I would assume that 0= -9-(12-3x) as it is not mentioned in the description

garri49 [273]

Answer:

She has 27 students now.

Step-by-step explanation:

Given :

The teacher has 30 students

10% students left.

To find : how much students does she have now?

Solution :

Since we are given that teacher has 30 students .

And 10% of students left

What is the measure of a°?
yuradex [85]

Answer:

<u>The correct answer is C. 129.</u>

Step-by-step explanation:

Let's recall that the Inscribed Quadrilateral Theorem states that a quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary.

In the case of the inscribed quadrilateral ABCD in the graph attached, we have that:

m∠C= 51°, therefore its supplementary angle, ∠A, should be the difference between 180° and m∠C.

m∠C= 180° - m∠A

Replacing with the real values:

51 = 180 - m∠A

m∠A = 129°

<u>The correct answer is C. 129.</u>
