Answer:
6 Pounds of Bananas will cost a total of $3
Barbara’s hourly rate is six dollars an hour
52 = (2*W - 5) * W
52 = 2*W^2 - 5*W
0 = 2*W^2 - 5*W - 52
0 = (2W - 13)*(W + 4)
2W - 13 = 0 or W + 4 = 0
W = 13/2 or W = -4
Width cannot be negative so discard W = -4
W = 13/2 L = 2*(13/2) - 5 = 13 - 5 = 8
Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
