Of couse, YES. The multiplication operation admits the commutative property:

$\boxed{\pi*2=2*\pi}$

That's a true statement. In fact, it doesn't even matter what the two numbers are.
'A' times 'B' is equal to 'B' times 'A', whatever they are.

One angle of a triangle measures 136°. The other two angles are congruent. Enter and solve an equation to find the measure x of

Juliette [100K]

136 + x + x = 180. Or, to simplify, 136 + 2x = 180. The congruent angles measure 23 degrees each.

We know this because of a simple rule that goes for all triangles: The measures of all three angles in a triangle will always add up to 180 degrees.

One angle of a triangle measures 136 degrees. The other two angles are congruent (have the same measure).

(x stands for an unknown angle measure.) So the equation we would use is 136 + 2x = 180. We can solve this within a few steps.

1. We subtract 136 from 2x in order to isolate 2x. But if we subtract something from the left side of the equation, we have to subtract it from the right side too. Otherwise the equation will be wrong; We would be taking away the balance.

2x = 180 - 136

2. Now that 2x is isolated, we solve 180 - 136.

2x = 46

3. If we know now that 2x is equal to 46, how do we find out what x is equal to? We divide by 2 (on both sides or it'll be wrong) to get x.

2x = 46

2x/2 = 46/2

x = 23

Now we know! x = 23... The other two angles are both 23 degrees. We can check to see if that's right by solving 23 + 23 + 136... Does it add up to 180? Yes! :)

Two less than seven times a number c is written as

Savatey [412]

Answer:

$7c-2$

Step-by-step explanation:

Let c be the number.

We are asked to write an expression for given verbal description.

7 times the number c would be $7c$ .

Two less than seven times a number means 2 subtracted from $7c$ .

Two less than seven times a number c would be $7c-2$ .

Therefore, our required expression would be $7c-2$ .

1/4 ÷ 2/3 show,step please

kicyunya [14]

$\frac{1}{4}$ ÷ $\frac{2}{3}$ is the equation

When dividing fractions, you "flip-flop" and multiply

So what that means is that you flip the second fraction and multiply

So $\frac{2}{3}$ is now $\frac{3}{2}$

Now the equation is $\frac{1}{4}$ × $\frac{3}{2}$ which equals $\frac{3}{8}$

Your answer is $\frac{3}{8}$
