What is the value of x? A.20 B.40 C.45 D.85

Step-by-step explanation:

Part 1: Determining the type of angles that need solved

First, we need to look at the angles provided to notice a key detail -- they add up to make a 90 degree angle. Therefore, we can just add the two values together, set them equal to 90, and solve for x.

Part 2: Setting up an equation

Now, using the information we just retrieved, we need to set up an equation for us to solve:

Part 3: Solving the equation

Finally, just solve for x:

    Subtract 10 from both sides to isolate the variable and its coefficient.

    Divide by 2 on both sides to isolate the variable.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
