Sum of interior angles in a triangle = 180

so

x + x + 12 + x - 9 = 180

3x + 3 = 180

3x = 177

x = 59

Can someone help me with this please? Thank you!
Finger [1]

Answer:

528 cm²

Step-by-step explanation:

First I would calculate the area of the side rectangles:

20 x 9 = 180 cm²

There are two identical rectangles on both sides so i would x2

180 x 2 = 360 cm²

The area of the middle rectangle:

6 x 20 = 120 cm²

The area of the triangles:

Area of a triangle = (Base x Height)/2

8 x 6 = 48

48 ÷ 2 = 24

There are two identical triangles on the bottom and the top so x2

24 x 2 = 48

Now add all the values up:

360 + 120 + 48 = 528 cm²

I hope this helps!

PLEASE HELP!!<br>1y+14=-4y+9 for y. Round your answer to the nearest tenth.​
slega [8]

Answer:

y = -1.0

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4y and subtract 14 from both sides:

1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)

1y + 4y = 9 - 14

Combine like terms:

5y = -5

Isolate the variable, y. Divide 5 from both sides:

(5y)/5 = (-5)/5

y = -5/5

y = -1

y = -1 is your answer.

Can i please get help with this question?
Aleonysh [2.5K]

1,5 . n = 13,65


We know:


1,5=\frac{15}{10}

and

13,65=\frac{1365}{100}


So,


\frac{15}{10}.n=\frac{1365}{100}


Pass \frac{15}{10} as division.


n = \frac{\frac{1365}{100}}{\frac{15}{10}}


Btw, we also know:


\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}


So,


n = \frac{\frac{1365}{100}}{\frac{15}{10}}

n = \frac{1365.10}{100.15}

n = \frac{13650}{1500}

n = \frac{91}{10}

n = 9,1
