Answer:
x= 11/12
Step-by-step explanation:
12x - 1 = 10
12x = 10 + 1
12x = 11, divide 11 by 12
you can't divide it evenly so leave it as a fraction.
can u put that question in letters please so i can look it up [;
i might know it if u put it in letters
Let's break down the problem step by step.
The sum of 4 times a larger integer can be summarized as:
4x
9 times a smaller integer can be summarized as:
9y
We know that we're adding the two expressions because the beginning of the problem has sum. We also know the sum is 3.
So, we get:
4x + 9y = 3
Continuing with the problem, we have the difference between 8 times the larger
8x
We also have 3 times the smaller
3y
This part of the problem mentions the difference between these expressions so we subtract and we know the difference is 27.
8x - 3y = 27
Now, we have both equations so we can solve for either x or y.
4x + 9y = 3
8x - 3y = 27
It's easier to multiply the 4x equation by 2 to have both equations resulting in 8x
(4x + 9y = 3) * 2
We get:
8x +18y = 6
So, we now have:
8x + 18y = 6
8x - 3y = 27
We can subtract the x to get y by itself. We get:
21y = -21
Solve for y and we get:
y = -1
Since we know what y is, we can plug that in and solve for x. It doesn't matter which equation you plug y back in. I'm gonna use the second equation.
8x - 3y = 27
8x - 3 (-1) = 27
8x + 3 = 27
8x = 24
x = 3
So, we now know that
y = -1
x = 3

Answer:
9 x 12 x 1/2 x 2 = (two area's of triangles on the sides) = 108
12 x 9 x 1/2 = (base triangle's area) 54
12 x 9 x 1/2 = (area of triangle behind) 54
Add given areas:
54 + 54 + 108 = 216 ft^2 I THINK.
Im really unsure about this.. please wait for more responses I REALLY am not sure about this answer.
The probability of rolling doubles is the probability of rolling any number time the probability of rolling the same number on the second die.
P(doubles)=(6/6)(1/6)=6/36=1/6
You can also think of it like this:
There are 6 doubles that you can roll out of 36 total possible rolls which is also:
6/36=1/6
