Answer:
W = P/2 - L
Step-by-step explanation:
WE need to make W the subject of
P = 2L + 2W
2W = P - 2L
W = ( P - 2L) / 2
or W = P/2 - L
The answer to the first problem is x=1
The answer to the 2nd problem is x=4
In the first problem, you need to subtract the 8 from both sides of the equation then divide 4 by both sides which makes 4 cancel itself out leaving x and 12 leaving 1.
Answer:
x = 6.00 $/kg ----> almond
y = 3.5 $/kg ------> nut
Step-by-step explanation:
To find the price per kg of each product you first write the algebraic equations for the given relations:
x : price per kg of almond
y: price per kg of nut
Then, you have:
5x + 4y = 44.00 (1)
8x + 6y = 69.00 (2)
By using substitution you have from (1):
y = (44.00-5x)/(4) = 11.00 - (5/4)x
you replace this expression for y into (2):
8x+6[11.00-(5/4)x] = 69.00
8x+66.00-(15/2)x = 69.00
8x-(15/2)x = 69.00 - 66.00
(1/2)x = 3.00
x = 6.00 $/kg ----> almond
And for nut:
y = 11.00 - (5/4)x = 11.00 - (5/4)(6.00) = 3.5$/kg
y = 3.5 $/kg ------> nut
The answer is X-2
The third answer
Black = 15
blue= 6
15 + 6 = 21
30-21 = 9
white t shirts = 9
