Answer: 182 gallons
find 30% of 260 by multiplying 260 by 30%
260 x .3 = 78
30% of 260 = 78
Subtract 78 from 260 to get original amount
260 - 78 = 182
Original is 182 gallons
ps. this is an actual impossible question because you need to know the original amount to find what 30% of it is. What i found was a 30% decrease of 260 not a 30% increase of the original. With that being said I think this is what you want?
Answer:
x= 4, y = -1
Step-by-step explanation:
2x-3y=11
3x+3y=9
do addition and you should get
5x=20
x=4
plug in x into any equation
12+3y=9
3y= -3
y=-1
Answer:
The angles are 54 2/3 degrees and 115 1/3 degrees
Step-by-step explanation:
make an equation for the angles x being one angle and y being the other
16+ 2x =y
Supplementary angles add to 180
x + y = 180
Fill in y with the first equation
x + 16 +2x =180
simplify
3x +16 =180
subtract 16 from both sides
3x = 164
divide both sides by 3
x = 54 2/3
Insert the value of x into the first equation then simplify
16 + 2(54 2/3) =y
16 + 109 1/3 =y
115 1/3 =y
The solution to this equation is: x<7
