Answer:
Adult tickets =125
Child tickets = 128
Step-by-step explanation:
Let the number of adult and children tickets sold be x and y respectively
So that
x+y= 253--------1
Since total sales/receipt is $2,771
And given that tickets for a dance recital cost $15 for adults and $7 for children hence
15x+7y= 2771-------2
Solving equation 1 and 2 simultaneously we have
x+y= 253---------------1
15x+7y= 2771----------2
Let us multiply equation 1 by 15 to get equation 3 to eliminate x and subtract equation 2 from 3
15x+15y=3795---------3
-{15x+7y= 2771----------2
0+8y=1024
8y= 1024
y= 1024/8
y= 128 tickets
So solve for x let us put y= 128 in equation 1
x+ 128=253
x=253-128
x= 125 tickets
Answer:
C, none of them are equivalent
BECAUSE
For A, the -4q should be positive 4q to apply
For B, the 2q when distributing with the parentheses should be negative 2q to work with the expression above
Hope this helps!
It is both equations are equal to -0.076.
Answer:
The first one would be the heaviest
Step-by-step explanation:
becuase if you compare all three of them vertically you wil see that the tenth in the first one is larger than the other two
Answer: y = -1/3x -5 (4th option is correct)
Step-by-step explanation:
- The slope of a perpendicular line is opposite reciprocal --> -1/3
- Find b.
- -4 = -3(-1/3) + b
- -4 = 1 +b
- -5 = b
