Answer:
The number of cups = 8 ....
Step-by-step explanation:
Let x be the number of cups
Let y be the number of plates
According to the given statement:
y=2x-4 This is equation 1
Now,
60% = 0.60
y=0.60(x+y) This is equation 2
Now substitute equation 1 in equation 2.
y=0.60(x+y)
2x-4=0.60(x+2x-4)
2x-4=0.6x+1.2x-2.4
Solve the like terms:
2x-4=1.8x-2.4
2x-1.8x=4-2.4
0.2x=1.6
x=1.6/0.2
x= 8 cups
Therefore the number of cups = 8 ....
The expression would be 34 - 1.5d
34 ounces minus 1.5 ounces multiplied by d (the amount of days that have gone by.)
Answer:
5 is the answer
Step-by-step explanation:
because it you add 5 to all the x values you get the y values
Answer:
Table C
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Find the value of the constant of proportionality in each table
Table A
For

This table has different values of k
therefore
the table A does not represent a proportional relationship
Table B

This table has different values of k
therefore
the table B does not represent a proportional relationship
Table C

This table has the same value of k
therefore
the table C represent a proportional relationship
Table D
