X=9/2

Thank youu , 12-3 equals 9, then divide 2 and the answer is 9/2

Hey there!

\huge{ \fbox{ \sf{x=9/2 }}}

2x+3=12

To solve, we will need to subtract 4 from both sides.

2x+3-3=12-3=2x=9\\2x=9

Now in our second and final step, we will have to divide both sides by 2.

\frac{2x}{2}=\frac{9}{2}  \\\frac{9}{2}\text{(ANSWER)}

Hope this helps!

\text{Please rate this answer and thank!}\\\text{-TestedHyperr}

1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2

3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54 
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2

5) now u ca do it

What is the greatest common factor of 10, 20, and 50?
Viefleur [7K]

Answer:

10

Step-by-step explanation:

first you need to find the prime factors of the three numbers

ex:

prime factor of 18= 2*3*3

prime of 24=2*2*2*3

there is one 2 and one 3 in common

greatest common multiple 2*3=6

so the greatest common multiple is ten because it is the only one that can divide between all three evenly.

10=10/10=1\\20=20/10=2\\50=50/10=5

so 10 is your answer

I do not need an explanation, just a simple angle number!
Murljashka [212]

Answer:

Step-by-step explanation:

a + 143 = 180    {Linear pair}

a = 180 - 143

a = 37

37 + 93 + b = 180 {Angle sum property of triangle}

130 + b = 180

         b = 180 - 130

         b = 40

c + b = 90

c  + 40 = 90

c = 90 - 40

c = 50

d + 120 = 180   {Linear pair}

d = 180 - 120

d = 60

? = 60 + 40         {Exterior angle property of triangle}

? = 100
