Please help me? I am confused.​

Step-by-step explanation:

12x > 9(2x - 3) - 15

12x > 18x - 27 - 15

12x > 18x - 42

42 > 6x

7 > x

so, this is true for all values < 7

so, x is in (-infinity, 7)

both ends but included - therefore the round brackets.

Answer:

7x+7

Step-by-step explanation:

10x + 7 - 3x

Combine like terms

10x-3x   +7

7x+7

Step-by-step explanation:

10x + 7 - 3x

= 10x - 3x + 7

= 7x + 7

Answer:

75 - x - 1.25y

Step-by-step explanation:

The expression written as a mixed number is 1 (11/20).

A fraction is a part of the whole represented by a/b, where a and b are any integers.

The given expression is 3 (3/4) - 2 (1/5).

Rewrite the expression as a mixed number:

3 (3/4) - 2 (1/5)

= 15/4 - 11/5

= (75 - 44)/20

= 31/20

= 1 (11/20)

Hence, the expression written as a mixed number is 1 (11/20).

x<1/-3

Step-by-step explanation:

Distribute -3 to (x+3)

-3x-9+5<-3

add like terms (-9+5=-4)

-3x-4<-3

add 4 to both sides

-3x<1

divide both sides by -3

x<1/-3

Using proportions, it is found that each out is [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Supposing a 9-inning baseball game, each team has the right to 27 outs.

Two teams, thus, there are [tex]2 \times 27 = 54[/tex] outs.

This means that each out in a game [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.

Each years the bank added a certain amount of interest.

At the end of the 2 years he gained 243 dollars and 60 cents just from interest.

How to solve:

Simply take away the 4 in the amount of money

Leaving: $243.60

( 2 years )

Now divide 243.60 by 1/2

which is 121.8

Mr.Chan got 121.8 worth of interest a year

$10.5 a month

$2.3 a week

6 cents a day

All in 2 years.

Answer:

9 sqrt(5)

Step-by-step explanation:

La altura relativa a la hipotenusa corta la hipotenusa en dos segmentos.

Defina x como

x = la longitud de uno de esos segmentos

Entonces, la longitud del otro segmento = 15 - x.

Entonces, por el teorema, tenemos que (15-x) (x) = 36, de modo que

15x - x ^ 2 = 36

x ^ 2 - 15x + 36 = 0

(x-3) (x-12) = 0

Entonces, x = 3 o x = 12.

Sin pérdida de generalidad. sea ​​x = 3.

Entonces, la suma de las dos piernas es

raíz cuadrada (6 ^ 2 + 3 ^ 2) + raíz cuadrada (12 ^ 2 + 6 ^ 2) =

raíz cuadrada (36 + 9) + raíz cuadrada (144 + 36) =

raíz cuadrada (45) + raíz cuadrada (180) =

raíz cuadrada (9 * 5) + raíz cuadrada (36 * 5) =

3 raíz cuadrada (5) + 6 raíz cuadrada (5) =

9 cuadrados (5)

Your square would be 64.

Step-by-step explanation:

If you think about if 8 is a square root of a number, the answer is yes. It's 64. When you multiply numbers by themselves, such as 2*2, or 8*8, you get their square. In this case, 8*8 is equal to 64.  I hope this helps you. : )
