Hi there,
73 indeed a prime number
A prime number<span> (or a </span>prime) is a natural number<span> greater than 1 that has no positive divisors other than 1 and itself. A </span>natural number<span> greater than 1 that is not a </span>prime number<span> is called a composite </span><span>number!</span>
Subtract 3y from each side of the equation.
The answer is "Math".....but technically the official name for it is Mathematics.
Answer:
see attached
Step-by-step explanation:
The steps to solving an equation are those that undo the operations done to the variable. Here, the variable is multiplied by 2/3 and 15 is added to the product.
We undo the addition of 15 by subtracting 15 (from both sides of the equation).
We undo the multiplication by 2/3 by multiplying both sides of the equation by its inverse, 3/2.
It is useful to do simplification after each of these steps.
Attention needs to be paid to the signs. When 15 is subtracted from 9, a negative result is obtained. When that is multiplied by a positive number (3/2), a negative result remains.
Answer:

Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.

Combine like terms (all terms with an x) on the left side.


Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.

x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.

Substitute 29 for x in the angle measures.
- 2x+6= 2(29)+6=58+6=<u>64</u>
- x=<u>29</u>
- 3x= 3(29)=<u>87</u>
<u></u>
The largest angle is 87 degrees.
