Hello!

You solve this algebraically

6(3 - 2x) = 54

distribute the 6

18 - 12x = 54

Subtract 18 from both sides

-12x = 36

Divide both sides by -12

x = -3

The answer is -3

Hope this helps!

Answer:

D. 1/44

Step-by-step explanation:

divide both sides by the # in front of X - in this case its 6. you should get x= 3/22 ÷ 6 and get your answer there by plugging in the calculator. or on paper-

do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways

There are four boys to every five girls in an introductory geology course. If there are 387 students enrolled in the course, how
mihalych1998 [28]

Answer: 172 boys.

Step-by-step explanation: The ratio of boys to girls is 4:5. We can say that the number of boys in the class is four multiplied by the common value that the ratio is based on. We can call this common value x and say that the number of boys in the class is 4x. Applying the same logic to the girls, we can say that there are 5x girls in the class. Thus, a total of 9x children. We divide the total value by 9 to get x, which equals 43. We can then retrieve the number of boys by calculating 4x, which equals 172.

Problem 1

<h3>Answer: Choice C) x^2-4 </h3>

Explanation:

Use the difference of squares rule here.

That rule says (a-b)(a+b) = a^2-b^2

In this case, a = x and b = 2.

===========================================================

Problem 2

<h3>Answer: Choice B) 2x^2+7x+5</h3>

Work Shown:

(2x+5)(x+1)

y(x+1) ..... let y = 2x+5

xy+y

x(y) + 1(y)

x(2x+5) + 1(2x+5) ... plug in y = 2x+5

2x^2+5x+2x+5

2x^2+7x+5

===========================================================

Problem 3

<h3>Answer: Choice A)  -x^2-5x+7</h3>

Explanation:

The standard form of a quadratic is ax^2+bx+c, where a,b,c are real numbers. In the case of choice A, we have a = -1, b = -5, c = 7.

===========================================================

Problem 4

<h3>Answer: Choice D</h3>

Explanation:

Along the top we have three green rectangles. If each of them are of length x, then we have x+x+x = 3x so far. Then adding on a yellow piece of 1 unit leads to 3x+1 as the total horizontal width across the top.

Similarly, along the left side we have 1 green portion and 2 yellow leading to x+2. So this shows why this diagram represents (3x+1)(x+2)

A rectangle must be formed with the smaller pieces glued together. We cannot have any gaps or overlaps. The reason we're aiming for a rectangle is because the area of a rectangle is length*width. Think of (3x+1) as the length and (x+2) as the width.
