Answer:
1.25*x=5/7 and it will take 1.607 gallons maybe
Step-by-step explanation:
we know he used 1.25 gallons to cover only 5/7 of the fence. we don't know the area of the fence. we use a variable for area. 1.25 gallons of paint times the area of the fenxe equaled 5/7 of the fence getting painted. you'd need more paint for the entire fence. solve for x says that x=0.57 was the area. so now we say that 0.57 only equated to 5/7 but we want 7/7 painted so so we need 2/7 more paint so we multiply 1.25 by 2/7 to find how much per for that area and we get 0.357. add 0.357 to 1.25 to get 1.607
6) The combined length for all of the 1/2 crystals is 2 inches.
7) The combined length for all of the 5/8 crystals is 1 7/8 inch.
8) The combined length for all of the crystals on the bracelet is 8 inches.
9) I got 0.571428 for an answer. I think it's right, but not completely sure. Sorry.
2 x 6,000=x(variable)

Answer:
(4²πx2) + (8π x 4) = 201.061... OR 64π
2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
