Solve linear equation y=4-x y=x-4

Hatshy [7]

{ y = 4 - x
y = x - 4

Subsititute y = x - 4

[ ( x - 4 )] = 4 - x ]

isolate x for ( x - 4 ) = 4 - x

x = 4

For y = x - 4

Subsititute x = 4

y = 4 - 4

y = 0

Solution

x = 4 and y = 0

hope this helps!

A triangle has angles measuring 30 degrees and 90 degrees the length of the included side is 6cm. tell whether the conditions fo

Alexxx [7]

Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : Two triangles are congruent if "ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle."

There is a photo attached drop down: 45 135 210 240

Alex_Xolod [135]

Taking the arcsin of both sides of the equation, you get ...

... 90° -x = {-60°, -120°}

So ...

... x = 90° -{-60°, -120°} = {150°, 210°}

The appropriate choice is ...

... 210

After eating 75% of the chocolates in a box, Dev found 6 chocolates remaining. How many chocolates were there in the box origina

Virty [35]

Answer:

Step-by-step explanation:

Let total number of the chocolates be x.

25% of x = 6 (because 100 - 75 = 25% of chocolates left).

25/100 x x = 6

x = 600/25

x = 24

Hence, 24 is the total amount of chocolates.

Hope it helps :)
