Answer:

x = 20

Step-by-step explanation:

6x - 10 = 3x + 50 {Vertically opposite angles}

6x = 3x + 50 + 10 {Combine like terms}

6x = 3x + 60 {Subtract 3x from both sides}

6x -3x = 60

3x = 60 {Divide both sides by 3}

x = 60/3

x = 20

What is the amount of interest earned with a deposit of 7,000 at 6.5% for 120 days

aev [14]

The interest figure always means the interest for a year.

120 days is 1/3 of a year, so you'll only earn 1/3 of 6.5% .

6.5% = 0.065

1/3 of that is 0.02167 .

(0.02167) x (7,000) = 151.67

Blizzard [7]

Answer:

y = 90

Step-by-step explanation:

Therefore, quadrilateral so formed is a rectangle.

Each angle of a rectangle is right angle.

$\therefore \: y \degree = 90 \degree \\ \\ \huge \red{ \boxed{ \therefore \: y = 90}} \\ \\$

For what value of x is line m parallel to line n? Enter your answer in the box. x = ?

Zielflug [23.3K]

Answer-

The value of x is 10

Solution-

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

As m and n are parallel line, so

$\Rightarrow 8x+50=130$

$\Rightarrow 8x=130-50$

$\Rightarrow 8x=80$

$\Rightarrow x=10$
