Problem 4: Option C, 32

Problem 5: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6: x = 17

Problem 7: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Step-by-step explanation:

Problem 4

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

Answer: Option C, 32

Problem 5

You need to have the 2 and the x combine. Make the table 2x than 16.

Answer: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

Answer: x = 17

Problem 7

She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Answer: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Factor the given quadratic function x2 + 9x = 36.

Gennadij [26K]

Answer:

(x + 12)(x - 3)

Step-by-step explanation:

${x}^{2} + 9x = 36 \\ {x}^{2} + 9x - 36 = 0 \\ {x}^{2} + 12x - 3x - 36 = 0 \\ x(x + 12) - 3(x + 12) = 0 \\ (x + 12)(x - 3) = 0$

the combined age of april and laura is 23 years. laura's age is two years more than half of april's age. what is laura's age

Kipish [7]

Laura's age is 9 years.

Solution:

Let x be the age of April.

Laura's age = 2 years more than half of April's age

Convert statement into algebraic expression:

Half of April's age = $\frac{x}{2}$

2 years more than half of April's age = $\frac{x}{2}+2$

Combined age of April and Laura = 23

⇒ April's age + Laura's age = 23

$$\Rightarrow \ \ x+(\frac{x}{2}+2) =23$

$$\Rightarrow \ \ x+\frac{x}{2}+2 =23$

$$\Rightarrow \ \ \frac{x}{1}+\frac{x}{2}+\frac{2}{1} =23$

To add the fractions make the denominators same.

Multiplying 2 on both numerator and denominator of unlike terms, we get

$$\Rightarrow \ \ \frac{x\times2}{1\times2}+\frac{x}{2}+\frac{2\times2}{1\times2} =23$

$$\Rightarrow \ \ \frac{2x}{2}+\frac{x}{2}+\frac{4}{2} =23$

Denominators are same, now add the fractions.

$$\Rightarrow \ \ \frac{2x+x+4}{2} =23$

Do cross multiplication.

$$\Rightarrow \ \ 2x+x+4=23\times2$

$$\Rightarrow \ \ 3x=46-4$

$$\Rightarrow \ \ 3x=42$

$$\Rightarrow \ \ x=14$

Aprils's age = 14 years

Laura's age = $\frac{14}{2}+2$

= 7 + 2

Laura's age = 9

Hence Laura's age is 9 years.

Help me on this question

NeX [460]

Answer:

$x = 18$

Step-by-step explanation:

Vertically Opposite Angles are equal..

so,

$x + 54 = 4x \\ 54 = 4x - x \\ 54 = 3x \\ \frac{54}{3} = \frac{3x}{3} \\ 18 = x$
