Since bot of the expressions in x are equal to y we can equate them as follows:-
6x + 9 = 7x + 7
9 - 7 = 7x - 6x
x = 2
and y = 6(2) + 9 = 21
THe answer is Choice B
Assuming the 100 people sampled are representative of the population as a whole, the answer is choice B. Most people who own a cat would dislike dogs according to the survey. We can only talk about cat owners since the 100 people selected are cat owners. We can't say anything about pet owners in general.
Answer:
v=m/d
Step-by-step explanation:
D=m/v
D*v=m
d*v/d=m/d
v=m/d
Lets denote the numbers x and y:
The sum of two numbers 94 → x + y = 94
Their difference is 12 → x - y = 12
We have:
x + y = 94
x - y = 12
---------------- Add both equations
2x = 106
x = 106/2
x = 53
Using first equation:
x + y = 94
53 + y = 94
y = 94 - 53
y = 41
A/ The numbers are 53 and 41.
