Answer:
8 weeks
Step-by-step explanation:
p = 2w
p = total pieces = 16
then putting value in p = 2w
16 = 2w
divide by 2 on both side we get
16/2 = 2w/2
8 = w
where w is total weeks i.e 8
Answer:
x = -1/8
Step-by-step explanation:
to determine the value of x in the expression-6=3/4x
first, cross multiply inorder to have a straight line equation ,then combine the like terms together and evaluate.
solution
-6=3/4x
using cross multiplication techique
4x × -6 = 3
-24x = 3
divide both sides by the coefficient of x which is -24
-24x/-24 = 3 /-24
x = -1/8
A = L * W
A = 54
L = 2W + 3
54 = W(2W + 3)
54 = 2W^2 + 3W
2W^2 + 3W - 54 = 0
(2W - 9)(W + 6) = 0
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <== width
W + 6 = 0
W = -6....it wont be this one because it is negative
L = 2W + 3
L = 2(4.5) + 3
L = 9 + 3
L = 12 <==length
