Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.

Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have $\sqrt{48x^4}$ , which I'm not sure if you want it simplified or not

Two angles are supplementary. Which of the following equations can be used to find the value of the missing angle, x, if the oth

Natali [406]

Two angles are said to be supplementary if their sum is 180 degrees. So, if x and y are supplementary angles, the formula is

$x + y = 180$

We know that one of the angles (say x) is 98. So, the equation updates to

$98 + y = 180$

If we want to solve for the other angle, we can simply subtract 98 from both sides to get

$y = 180-98 = 82$

Answer:

3. 9n + 6 = 78

5. see below

Step-by-step explanation:

Let the number of adults be n. Each adult ticket costs $9, so the cost of n adult tickets is 9n. There is only one child, and a child's ticket is $6, so the cost of the child's ticket is 6. Adding the costs, you get 9n + 6. The total cost is $78, but the expression representing the total cost is 9n + 6, so 9n + 6 must equal 78. That is the equation.

9n + 6 = 78
