Step-by-step explanation:
Did it on edge just now !
1000+9 x 100 + 9 x 10 + 3 x 1 or 1000 + 900+ 90 + 3
Question 1: you would divide 13 from both sides of the equation, making the answer w = 3
Question 2 : you would divide 11 from both sides of the equation, making the answer x = 5
Question 3: the answer is already there, it's r = 5

Answer:
$19.36
Step-by-step explanation:
Any average is the sum of numbers, divided by the number of them.
Here, the numbers are grouped, but the computation of the average works the same way.
The total value of donations received is ...
$100×10 +$50×20 +$20×30 +$10×100 +$5×35
= $1000 +1000 +600 +1000 +175 = $3775
The total number of donations received is ...
10 +20 +30 +100 +35 = 195
Then the average (mean) donation is the total value divided by the total number ...
$3775/195 ≈ $19.35897 ≈ $19.36 . . . mean donation
