Answer:

x = -1

y = 4

Step-by-step explanation:

i believe this shape is a rhombus because the diagonals are perpendicular and bisectors, meaning m∡A = m∡B = m∡C = m∡D

so AC = CB = BC = DA

y + 1 = 2y - 3

1 = y - 3

4 = y

Plugging in 4 for 'y' means all sides are equal to 5

find x: 2x + 7 = 5

2x = -2

x = -1

Answer:2516 pounds

Step-by-step explanation:

find the difference in gallons and the difference in the weights

46 - 14 = 32 gallons

2399 - 2191 = 208 pounds

so 32 gallons of gas weighs 208 pounds

find weight per pound: 208 pounds / 32 gallons = 6.5 pounds per gallon

round to 6.5 pounds per gallon

64 gallons - 46 gallons = 18 gallons

18 gallons x 6.5 pounds per gallon = 117 pounds

2399 + 117 = 2516 weight of plane with 64 gallons
