It is not a very tough question as it has all the information's required to find the necessary answer. It is already given that 82 1/2% of a certain number is 330. It is required to find the unknown number. So we have to create an equation with a single unknown number.
Let us assume the number to be = x
then we can easily write the equation as given below.
82 1/2% x = 330
(165/4)%x = 330
(165/400)x = 330
x = (330 * 400)/165
= 2 * 400
= 800
So the unknown number is 800.
I THINK this is how you do it:
4q=76
q=19
19+10 (wrong answers)=29

Answer:
y - 2 = 3(x + 1)
y - 2 = 3x + 3
y = 3x + 5
Step-by-step explanation:
Answer: x=4
Step-by-step explanation:
similar triangle so corresponding parts are similar
cross multiply
70 = 20x-10
80 = 20x
x = 4
Here is the work! The zeros of the graph are at -1 and 3
