Answer:
B
Step-by-step explanation:
-36-8= -36+(-8)
Well to solve these type of question it is very easy to make a tree diagram and then solve them. How ever i have done it here for you.
So basically we have to get a pen from the first box so its probability is 7 / 10.
Similarly, we have to get a crayon from the second box so its probability is 2 / 8.
Now by counting principle we can multiply the two probabilities so 7/10 * 1/4 which becomes equal to 7/40.
The graph would be a compressed inside down U shape
(-7,45) (-6,48) (-5,49) (-4,48) (-3,45)
Answer:
b = 3c
B = 4c
Step-by-step explanation:
2b + B = 8c
B - b = 2c
_____________ (-)
2b + B - B + b = 8c - 2c
3b = 6c
b = 6c : 3
b = 2c
B = 2c + b
= 2c + 2c
= 4c
Hey there! :)
Equation 1) -2x + y = 14
Equation 2) 4x - 6y = 4
Add 2x to both sides of equation 1 so that we can get the value of y.
y = 2x + 14
Now, plug the value of y into our second equation.
4x - 6(2x + 14) = 4
Simplify.
4x - 12x - 84 = 4
Add 84 to both sides.
4x - 12x = 4 + 84
Simplify.
-8x = 88
Divide both sides by -8.
x = -11
Now, plug our value of x into our first equation in order to find y.
-2x + y = 14
-2(-11) + y = 14
22 + y = 14
y = -8
Therefore, the systems of equation variables are : (-11, -8)
~Hope this helped! :)
