if a triangle is an equilateral triangle then the triangle has exactly three 60 angles abc is an equilateral triangle

Artist 52 [7]

Answer:

The statement is always TRUE

Step-by-step explanation:

An equilateral triangle has all angles and all sides equal

The sum of angles in a triangle is 180 degrees.

Let each of the angles be x degrees.

Then we solve the following equation for x.

$x+x+x=180\degree$

$\implies 3x=180$

$\implies x=\frac{180}{3}=60\degree$

José collects stamps. He has 7 used stamps for every 4 new stamps. If he has 28 new stamps, how many used stamps does he have?

jenyasd209 [6]

Answer:

José has 49 used stamps

Step-by-step explanation:

7 used stamps for every 4 new stamps

To solve this type of problem, we can use a ratio

7 : 4 ratio

He has 28 new stamps

7 : 4 = x : 28

Ratios can be written as fractions

$\frac{7}{4} = \frac{x}{28}$

Cross multiply

4x = 7(28) = 196

Divide by 4 on both sides

x = 49

Hope this helps :)

Please help solve the equation above.

Paladinen [302]

Answer:

x=12

Step-by-step explanation:

(9x-4)+(5x+16)=180

14x+12=180

-12 -12

14x=168

then devide both sides by 14

x=12

X - 5y = 10; (0, -2) Group of answer choices no yes

mr Goodwill [35]

Yes, this linear equation is correct on point (0,-2).

Given that:

The linear equation

x - 5y = 10;

The point

(0, -2)

To find

We have to prove LHS = RHS

So, according to the question

We have,

The linear equation,

x - 5y = 10; and point is (0,-2)

From equation,

x - 5y = 10

Take the left part of given linear equation,

LHS = x - 5y

Now, putting the values, x = 0 and y = -2.

Then, we will be get.

= x - 5y

= (0) - 5 ×(-2)

= - 5 × -2

= 10.

So, we can say that

LHS = RHS.

Where,

LHS = Left Hand Side.

RHS = Right Hand Side.

We can solve that linear equation in other way,

When we put x = 0, we get y = -2.

So, if we put x = 1, we get y = -9/5.

Similarly, if x = 2, then y = -8/5.

Now, we can say that points (0,-2), (1,-9/5) and (2,-8/5) are lie in the linear equation x - 5y = 10.
