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

Mathematics

Answer:

x = 1

Step-by-step explanation:

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

7x - 20 = 2x - 9x - 6

7x - 2x + 9x = - 6 + 20

14x = 14

x = 14/14

x = 1

Answer:

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

We move all terms to the left:

7x-20-(2x-3(3x+2))=0

We calculate terms in parentheses: -(2x-3(3x+2)), so:

2x-3(3x+2)

We multiply parentheses

2x-9x-6

We add all the numbers together, and all the variables

-7x-6

Back to the equation:

-(-7x-6)

We get rid of parentheses

7x+7x+6-20=0

We add all the numbers together, and all the variables

14x-14=0

We move all terms containing x to the left, all other terms to the right

14x=14

x=14/14

x=1

In the figure below what is the value of x?
vazorg [7]

Answer:

The value of x is 106

Step-by-step explanation:

Let us solve the question

In the given figure

∵ The triangle in the given figure has two sides equal

→ That means the triangle is an isosceles triangle

∴ The triangle is isosceles

∵ In the isosceles triangle, the base angles are equal in measures

∵ The measure of one base angle is 37°

∴ The measure of other base angle is 37°

→ The sum of the measures of the interior angles of a Δ is 180°

∵ 37° + 37° + x = 180°

→ Add the like terms

∴ 74° + x = 180°

→ Subtract 74 from both sides

∵ 74 - 74 + x = 180 - 74

∴ x = 106

∴ The value of x is 106

oksian1 [2.3K]

Answer:

(x - 4)(x + 9)

Answer C is correct.

Step-by-step explanation:

{x}^{2}  + 5x - 36 \\  {x}^{2}   +  9x  - 4x - 36 \\ x(x  + 9)  -  4(x   +  9) \\  = (x  -  4)(x  + 9)

hope this helps

Set 1: 8, 15, 13, 7, 11, 17, 13
Schach [20]
Set two contains an outlier, which is 100
The measure of spread that was most impacted by the outlier is the range
This is because in set two, the median,both quartile and the interquartile range are all closely grouped together but the range is 93, which is far far away from any of those other values
