The numbers are "x" and "y",
we suggest this system of equations.
x+y=24
x-y=15
solve by reduction method.
x+y=24
x-y=15
-----------------
2x=39 ⇒x=39/2=19.5
x+y=24
-(x-y=15)
-------------------
2y=9 ⇒y=9/2=4.5
The numbers are 19.5 and 4.5
To check
19.5+4.5=24
19.5-4.5=15
The values that completes the table are 28, 9, 33, 32 and -3
<h3>Tables and values.</h3>
Tables are used to represents the dependent and independent variable of a function. They are used to formulate function.
From the given table, we are to think of any dependent value and subtract 3 from it to get the equivalent independent value.
From the third column;
a3-3 = 25
a3 = 25 + 3
a3 = 28
For the fourth column
a4 = 12 - 3
a4 = 9
For the fifth column
a5-3 = 30
a5 = 30 + 3
a5 = 33
For the sixth column
a6-3 = 29
a6 = 29 + 3
a6 = 32
For the seventh column
0-3 = a7a
a7 = 0 - 3
a7 = -3
Hence the values that completes the table are 28, 9, 33, 32 and -3

Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)
Answer: 43 cents
Step-by-step explanation: divide 6.00 by 14 which gives you around .42857
then you round to the hundredths place which gives you .43
