Let's label the man's age "x" because it's the unknown value that we're trying to find. Remember that the daughter's age is represented y "a."

x = 4a-3 would be an expression to represent the man's age :)

Answer:

16, 60, 20

Step-by-step explanation:

This is an equilateral triangle and since the LN is 16, LM must be as well.

The second, again is equilateral, so the angles must all be 60 degrees.

The last question is equilateral so all angles are equal to 60, and 60/3 is equal to 20.

I am Lyosha [343]

Answer: 40 students.

Step-by-step explanation:

To solve this problem you mmust apply the steps shown below:

1. You know that there is a total of 100 students, then you can say that the 100% is 100 students.

2. Then, to calculate how much would 40% be, you must multiply 100 students by 40% which you rewrite as a decimal by dividing it by 100, as following:

40%/100=0.4

Then 40% of the students would be

100 studens*0.4=40 students

A tree is 58 inches tall. how tall is it in feet and inches
mart [117]
A foot is 12 inches.
12 can go into 58 evenly 4 times, since 12• 4 equals 48 but 12 • 5 equals 60. This means that the tree is at least 4 feet. Then to find the leftover inches we do 58-48 equals 10, therefore the answer is 58 inches translates to 4 feet and 10 inches.
