Mathematics

AlladinOne [14]2 years ago
4 0

Answer:

B. x = 3

Step-by-step explanation:

Simplifying

4 + 3x = 2(3x + -7) + 9

Reorder the terms:

4 + 3x = 2(-7 + 3x) + 9

4 + 3x = (-7 * 2 + 3x * 2) + 9

4 + 3x = (-14 + 6x) + 9

Reorder the terms:

4 + 3x = -14 + 9 + 6x

Combine like terms: -14 + 9 = -5

4 + 3x = -5 + 6x

Solving

4 + 3x = -5 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

4 + 3x + -6x = -5 + 6x + -6x

Combine like terms: 3x + -6x = -3x

4 + -3x = -5 + 6x + -6x

Combine like terms: 6x + -6x = 0

4 + -3x = -5 + 0

4 + -3x = -5

Add '-4' to each side of the equation.

4 + -4 + -3x = -5 + -4

Combine like terms: 4 + -4 = 0

0 + -3x = -5 + -4

-3x = -5 + -4

Combine like terms: -5 + -4 = -9

-3x = -9

Divide each side by '-3'.

x = 3

Simplifying

x = 3

Answer:

The father was either 29 or 28 years old when the author of the question was born.

El padre tenía 29 o 28 años cuando nació el autor de la pregunta.

Step-by-step explanation:

English Translation

My grandmother gave birth to my father, when she was under 20 years old, and I was born when my father was over 25 years old, if my father is now under 45 years old and I was in my fourth year of high school, how old is my father when I was born.

Solution

Assuming that the author of the question is a typical fourth year high school student.

The age of fourth year high school students normally range from 16 to 17.

The father is currently 45 years old, so the age of the father when the author of the question was born is given as

(45 - 16) or (45 - 17)

= 29 or 28 years old.

which satisfies the condition given in the question that the father was more than 25 years old!

Hope this Helps!!!

(45 - 16) or (45 - 17)

Anna11 [10]

Answer:

A

Step-by-step explanation:

since the line is parallel, it will have the same gradient. from this, we can deduce that tbe equation will also start with y = ⅕x.

next, we see that it passes through the point (0,6). what this means is, when x = 0, y = 6 which is better known as the y intercept. so in the form y= mx + b:

the equation of the line is y = ⅕x + 6

Please help me with this question.
Rasek [7]
The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
