Answer:
1 5/24 total gallons remain
Step-by-step explanation:
yellow: 4/3 - 3/4 = 16/12-9/12 = 7/12
green: 5/4 - 3/4 = 5/4-3/4 = 2/4
blue: 7/8 - 3/4 = 14/16-12/16 = 2/16
7/12 + 2/4 + 2/16 = 28/48 + 24/48 + 6/48 =
58/48 or 1 5/24
Answer:
900°
Step-by-step explanation:
interior angles of a polygon = (n−2)×180°, where n is number of sides

Answer:
it ARBY'S
Step-by-step explanation:
Answer:
8a + 2b is 14 and b - 2a is 4 1/2
Step-by-step explanation:
divide 8 by 2 to get 4 and multiply 2 times 5 to get 10, then add 10 + 4
If b=5 and a is 1/2 then 5 - 1/2 = 4 1/2
Answer:
2x^2+14x-240=0
Step-by-step explanation:
Remember Pythagoras's theorem?
a^2+b^2=c^2
So over here,
x^2+ (x+7)^2= 17^2 [ we need to now simplify (x+7)^2 --> (x+7) (x+7) ]
x^2+ x^2+7x+7x+49= 289
2x^2+ 14x+49= 289
2x^2+14x+49=0 [ we need to make the right side zero coz thats
the rule for ]
2x^2+14x-240=0
(idk, but i think the "show that x^2.....) is wrong)
