The answers are 3/8 and 1/6.
There are 8 possible outcomes in the sample space for flipping 3 coins. Of those, 3 include two heads and 1 tail. This makes the probability 3/8.
Choosing a quarter for the first coin is 3/10, since there are 3 quarters out of 10 coins. After this, choosing a dime is given by 5/9, since there are 5 dimes out of 9 coins left:
3/10(5/9) = 15/90 = 1/6
<span>6x+7=6
Subtract both sides by 7
</span>6x+7-7=6-7
6x=-1
Divide both sides by 6 to isolate x
6x/6=-1/6
x=-1/6
THE HALF OF 3/4 WOULD BE 0.375
Answer:
x=20
Step-by-step explanation:
Well we know the right angle is 90 so...
And we also know that all the angle of a triangle add up to 180°.
Knowing this you can subtract 40° and 90°, this gives you 50°...
Then you can substitute 20° for x and then it will be 2(20°)+10°
Simplify and get 40°+10°
This equals 50° degrees
You then add that all up and you get 180°, this mean the answer is correct!
Hope this helps!

To solve for y you have to simplify both sides of the equation, then isolating the variable which equals to...
y = -4x/3 + 4
Next, you have to move all terms that don't contain y to the right side and solve.
y = 10 + 2x/3
____
Now we solve the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-3,8)
Equation Form: x = -3, y = 8
____
Leaving it to be the only choice which is 'D.) 8', I hope this helps, as always. I wish you the best of luck and I hope you have a nice day..
