The answer is about 28-30 people who were surveyed.
Answer:
D
Step-by-step explanation:
128/2 = 64
The squareroot of 64 = 8
That means that only C or D could be true; 8 is in the numerator not the denominator.
Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.
There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.
Answer 8sqrt(y)/x
D
Answer:
The points are 
= ( 0 , - 2 ) and 
= ( - 3 , 0 )
These points is plotted on the x-y graph
Step-by-step explanation:
Given linear equation as :
4 x + 6 y = - 12
now, Let the points for the equation be
and
Now, From equation
For, x = 0
4 × 0 + 6 × y = - 12
Or, 0 + 6 × y = - 12
∴ y = 
I.e y = - 2
So, = ( 0 , - 2 )
Again
For, y = 0
4 × x + 6 × 0 = - 12
Or, 4 × x + 0 = - 12
∴ x = 
I.e x = - 3
So, = ( - 3 , 0 )
So, The points are = ( 0 , - 2 ) and = ( - 3 , 0 )
Now, These points is plotted on the x-y graph Answer
Answer:
4.5 or just say 4 if your gonna round it up. hope this helped :)
Step-by-step explanation:
Answer:
144,148,152
Step-by-step explanation:
Here we will have, 4x + 4(x+1) + 4(x+2) = 444
=> x + (x+1) + (x+2) = 111 (dividing both sides by 4)
=>x + x+1 + x+2 =111
=> 3x + 3 = 111
=> 3x = 108
=> x = 36.
So, the three desired numbers 4x, 4(x+1) and 4(x+2) are,
4*36, 4*(36+1) and 4*(36+2)
That means the numbers are, 144, 148 and 152.
