Since the probability of roling 12 is 1/36 we subtract that from how many possibiliies there are and we do this
36/36 (or 1)-1/36=35/36
So here is how you solve for the answer.
Firstly, you solve for the Area of Rectangle A.
The formula for Area is Length x width.
So A = (2x + 6)(3x) and the result is: 6x^2 + 18x
Now, let y be the width of rectangle B.
<span>(x+2) (y) = 6x^2 + 18x + 12
(x+2) y = 6(x+1)(x+2)
y = 6(x+1)
</span>So the final answer would be width is 6x + 6. The answer is the third option. Hope this answer helps.
31^8 (31 to the 8th power)
Answer:
- Variable x in first equation
Step-by-step explanation:
<u>Given system</u>
Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see <u>variable x is isolated </u>in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
So perm cost 2 times as hair cut
perm=2 times haircut
she also needs 5 dollars for lunch
so therefor if 95 is enough to cover it we do
cost=lunch+perm+haircut
cost=5+perm+haircut
subsitute
95=5+2 times haircut+1 time haircut
add like terms
95=5 +3 times haircut
subtract 5 from both sides
90=3 times haircut
diide by 3
30=haircut
subsitute
perm=2 times haircut=2 times 30=60
perm=$60
