Answer:
3,623 R6
Step-by-step explanation:
When the value of x = -2 then, the value of y is 5.
When the value of y = -2 then the value of x is -0.25
Explanation:
Given:
-2y - 8x = 6
Considering x = -2
Then, we have to substitute the value of x = -2 in the equation.
-2y - 8(-2) = 6
-2y + 16 = 6
10 = 2y
y = 5
So, when the value of x = -2 then, the value of y is 5.
Considering y = -2
Then, we have to substitute the value of y = -2 in the equation.
-2 (-2) - 8x = 6
4 - 8x = 6
-2 = 8x
x = -0.25
So, when the value of y = -2 then the value of x is -0.25
Let's write out what we do know...
70% of the people are under 16 years old
From this information, we can infer that 30% of the people are 16 or older.
100%-70%=30%
1/3 of the people 16 or older are teachers. There are 21 teachers.
1/3 of 30% is 10%
1/3*.30=.10 or 10%
So 21 is 10% the total number of people at the fair.
(I cross multiplied and then divided both sides by 10 to get x=210)
There are 210 people at the fair.
A.
150 people
B.
15 people
C.
25 people
D.
75 people
Answer: 15
Step-by-step explanation:
subtract 75 from 90 to get 15. those 15 people belong to the group who likes drama but are not buying popcorn. 150-90=60 which is how many people like dramas.
