The answer to the equation is X = 7
We know that
<span>4 1/2 gallons-------> (4+2+1)/2-----> 9/2 gallons
</span>
1 <span> wall in the house will need --------> 3/4 of a gallon of paint
</span> X wall-----------------------------------> 9/2 gallons
x=(9/2)/(3/4)----> 9*4/2*3-----> 36/6----> 6 walls
the answer is
6 walls
Answer:
(x, y) = (-2, -3)
WORK:
2x + 4y = -16 =
-2x + 2y = -2 =
(^ the two’s cancel out) =
6y = -18 =
(^ you need to divide 6 on both sides to get just y) =
6y/6 = -18/6 =
(^ the six’s cancel out) =
y = -3 =
(^ now you have to plug this in to get x) =
2x + 4(-3) = -16 =
2x - 12 = -16 =
(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =
2x = -4 =
2x/2 = -4/2 =
(^ now you divide 2 on both sides again to get just y, and they will cancel out) =
x = -2 =
THEREFORE YOU GET (-2, -3)
Answer:
geometry ?
Step-by-step explanation:
If so I gotchu this is my subject
I think it’s 309 cm because each side is 1 cm, there’s 3 sides, and 103 triangles. so 103x3=309 sides which means 309 cm
