Answer:15

Step-by-step explanation:

we know from the markings on the sides of the triangle that this is an equilateral triangle. The angles of an equilateral triangle are all equal. because of this, we can put these two equations to equal each other
since we are solving for y, we want to isolate y on one side.

6x+6=5y+10
-10 -10
6x-4=5y
divide both sides by 5

6/5x-4/5=y

What is the solution of x + 6 11
C. x –1

PLSS SHOW YOUR WORK PLSS

Answers

Is it 611 or is there something in between

Answer: x < -1

Step-by-step explanation:

x + 6 < 5

x + 6 = 5

x = -1

x < -1

Now try to prove its correct

A number less than -1 is -2 so we'll try that.

x + 6 < 5

(-2) + 6 < 5

4 < 5

We can tell after substituting -2 for x, that the answer is correct

Oh and I changed the less than sign to an equal sign so it's easier to solve.

After the 4th half life how much of the sample is left if the mass is 100g.

Answers

Answer:

[tex]\huge\boxed{\sf 6.25 \ g}[/tex]

Step-by-step explanation:

After every Half life , Half of the mass is left.

After 1st Half life = 100 g / 2 = 50 g

After 2nd Half life = 50 / 2 = 25 g

After 3rd Half life = 25 / 2 = 12.5 g

After 4th Half life = 12.5 / 2 = 6.25 g
