Answer:

x<13

Step-by-step explanation:

4x+12<64

Subtract 12 from both sides.

simplify 64 to 52.  

Divide both sides by 4.

simplify 52/4 to 13

Answer:

The numbers are 12 and 8

Step-by-step explanation:

let the numbers be x and y :

[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]

add (a) and (b):

[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]

find y:

[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

Answer:

16

Step-by-step explanation:

f(x) = 2x + 4

f(6) = 2(6) + 4

=> f(6) = 12 + 4

=> f(6) = 16

Given sides of the triangle:

We know that the perimeter of a triangle is the sum of all the sides of a triangle.

Perimeter of the triangle,

= 3x^2 + 8 + 2x^2 + x + x - 3

= 3x^2 + 2x^2 + x + x + 8 - 3

= 5x^2 + 2x + 5

Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.

The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint

AB + BC = AC

9x + 7 + (-3x + 20) = 39

9x + 7 - 3x + 20 = 39

6x + 27 = 39

6x = 39 - 27

6x = 12

x = 12 / 6

x = 2

9x + 7 = - 3x + 20

9(2) + 7 = - 3(2) + 20

25 = 15

Hence,

Since, AB ≠ BC, then B is not the midpoint

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

mark me brainliest plz

Answer:

[tex]d = a_{2} - a _{1}[/tex]

d is the common difference

a1 is the first term, a1 = 27

a2 is the second term, a2 = 11

substitute:

Answer:

[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]

Step-by-step explanation:

[tex]2\left|3x-2\right|=14[/tex]

⇒ Divide both sides by 2

[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]

[tex]\left|3x-2\right|=7[/tex]

⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a

[tex]3x-2=-7\quad[/tex]

or...

[tex]3x-2=7[/tex]

Now,

[tex]3x-2=-7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=-7+2[/tex]

[tex]3x=-5[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]

[tex]x=-\frac{5}{3}[/tex]

[tex]3x-2=7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=7+2[/tex]

[tex]3x=9[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{9}{3}[/tex]

[tex]x=3[/tex]
