Answer:
21 cm
Step-by-step explanation:
Since this is an isosceles triangle, the two sides with a line through them must have the same value of x. Therefore, you can set up the following equation:
2x+11=53
2x=42
x=21 cm
Hope this helps!
Answer: 
Step-by-step explanation:
Let "x" represents the 16% of 43 minutes.
Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.
Then, with this data, you can set up the following proportion:

Now you must solve for "x". The steps are:
- Multiply both sides of the equation by "x"

- Multiply both sides by 43:

- Divide both sides by 100:

- Rounding to the tenths place:

C, because half of 50 is 25 therefore since it has landed on the head 28 which is a little bit more means the answer is gonna be a little more than 50%
Answer:
4
Step-by-step explanation:
A function must pass the vertical line test, which means that two coordinates cannot have the same x coordinate. (They can't be directly above each other.)
ANSWER:
-8
REASONING:
Because the left of 0 is negative number and the right is positive therefore if you go to the left 4 more times then it is -8
