The trick to solving this problem is to know and remember that the sum of all the interior angles of a triangle is always 180 degrees.
Thus, (6x+1) + (5x-17) + (9x-24) = 180.
20x = -40, so x = -2 (answer)
Answer: Area = Length times width
Area = (3w + 7) x w
Area = 3(3 x 3 + 7) x 3 = 48 m^2
Step-by-step explanation:
Area = Length times width
Area = (3w + 7) x w
Area = 3(3 x 3 + 7) x 3 = 48 m^2
Answer:
D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges
Step-by-step explanation:
Price per pounds of bananas = b
Price per pound of oranges = b + $0.75
Diego buys:
3 pounds of bananas = 3(b) = 3b
2 pounds of oranges = 2(b + 0.75)
Amount paid by Diego is expressed as:
3b + 2(b + 0.75) = 4.50
To find the price per pound of each fruit, use the equation above to find the value of b:
3b + 2b + 1.50 = 4.50
Combine like terms
5b + 1.50 = 4.50
5b + 1.50 - 1.50 = 4.50 - 1.50
5b = 3
5b/5 = 3/5
b = 0.6
Price per pound of banana = b = $0.6
Price per pound of oranges = b + $0.75
Plug in the value of b
= $0.6 + $0.75
= $1.35
Is x=1/3 a possible answer? It would be if in fraction form.
or -31.
