Answer:
x = -11/2
Step-by-step explanation:
The ratios need to stay the same
5x 11
----- = -------
x-2 3
Using cross products
5x*3 = (x-2) 11
15x = 11x - 22
Subtract 11 from each side
15x-11x = -22
4x = -22
x = -22/4
x = -11/2
Answer:
GCF=2 LCM=140
Step-by-step explanation:
Let the total number of questions in the math test be defined by the variable x.
Now, we know that Parker correctly answered 35 questions. These 35 questions make 70% of the total number of questions on his math test.
The information we have above can be expressed as an equation given below:
70% of x=35
This can be rewritten as:

Thus, to find the total number of questions we will have to isolate x.

Therefore, there were a total of 50 questions in the math test.
Since that is a triangle the expression would be b x h / 2. So 12*12 = 144 / 2 = 72. The answer is 72.
To find the ratio of centimeters to meters you need to divide 66 by 33 to get 2.
Then multiply 2727 by 2 to get 5454.
