An algebraic expression that represents the weight of the fruit that Pascal still has after feeding the birds is 26.7 - 1.7w.
The total pounds of fruit that Pascal has after feeding the birds can be determined by subtracting the sum of the pounds of fruits he sold and the pounds of fruits he uses to feed the birds from the total pounds of fruit he had at the beginning of the day.
Pounds of fruit left = pounds of fruit he had at the beginning of the day - (pounds of fruit he sold + pounds of fruits he used to feed the birds)
Pounds of fruit he sold = 5 x w = 5w pounds
Pounds of fruits he used to feed the birds = 
×
= 53.3 - 3.3w
Pounds of fruit left = 80 - (5w + 53.3 - 3.3w)
After combining similar terms, the expression is:
26.7 - 1.7w

Answer:
1. y=-x
2. y=-3/2x-2
3. x=4
4. y=-2x-1
Step-by-step explanation:
slope intercept form is y=mx+b with mx being the slope and b being the y intercept
if its parallel it has to have the same slope.
perpendicular lines have the opposite slope and sign. so if its a whole number you put it over 1 and if its a fraction you switch the values in the numerator and denominator in addition to changing the sign. You keep the y intercept the same.
I should say that 13, 24, 14 are the next three numbers, because as you can see above the first(11) number is the third(12) number minus 1 and the fourth(23) is the second (22) plus 1 if you understand what I`m trying to say
Radio Barn : 200 + .15 x x = the weekly sales
Woofer: 300 + .10x
set them equal to find when they are them same
200 + .15x = 300 + .10x
subtract .10x from both sides
200 +.15x -.10x = 300 + .10x-.10x
200 +.05x = 300
subtract 200 from each side
200+.05x -200 = 300-200
.05x = 100
divide each side by .05
.05x/.05 = 100/.05
x =2000
The 2 jobs pay the same when the weekly sales are 2000 dollars
2. {x - 5 = -y}
{2y - 10 = -2x}
x-5 = -y
add 5 to each side
x = -y+5
multiply each side by -2
-2x = 2y -10
the 2 equations are the same, it has an infinite number of solutions
The system is dependent since the 2 equations are the same line
3. {2x = y - 7}
{4x - 2y - 14 = 0}
2x = y-7
subtract y-7 from each side
2x - (y-7) = 0
2x -y+7 =0
multiply by 2
4x -2y +14 =0
subtract the two equations
4x -2y +14 =0
4x - 2y - 14 = 0
---------------------------
28 = 0
since this cannot happen the lines will never cross ( parallel lines)
the system is inconsistent
Aidan has put 21 hours of work. To simplify it, Harry worked 7 hours and Aidan worked 7 x 3 times which equates to 21 hours.
