To figure this out, you need to multiply all the dimensions together. 100x30=. 3,000cm and 3,000x12= 36,000 cubic centimeters. So now you can divide the 36,000 by 1000 to get the amount of liters the entire tank can hold. 36,000/1000= 36 liters. And because you want to know how much half of the tank is, you divide 36 by 2 and get 18 liters
1. substitution....because it would be easier to just sub one y in for the other then it would be to use the elimination method
2. substitution....because in one of the equations, u already have y...so just sub 6x - 13 in for y in the other equation
3. elimination....all u have to do is add them and ur y terms are eliminated, allowing u to find x
4. substitution....sub in x + 1 for y in the other equation
2x + 4(x + 1) = 28 y = x + 1
2x + 4x + 4 = 28 y = 4 + 1
6x = 24 y = 5
x = 4
the solution for this system is : (4,5)
5. elimination..
3x - y = -1 3(-2) - y = -1
2x + y = -9 -6 - y = -1
------------------add -y = -1 + 6
5x = -10 -y = 5
x = -2 y = -5
the solution to this system is : (-2,-5)
6. substitution.....sub in one y for the other
2/3x - 1 = -x + 4 y = -x + 4
2/3x + x = 4 + 1 y = -3 + 4
5/3x = 5 y = 1
x = 5 * 3/5
x = 3
so the solution to this system is (3,1)
7. substitution...sub one y in for the other
296 - 10x = 200 + 6x y = 200 + 6(6)
296 - 200 = 6x + 10x y = 200 + 36
96 = 16x y = 236
6 = x
so the solution for this system is (6,236)
Answer:
D
Step-by-step explanation:
Answer:
(A)
Step-by-step explanation:
Given: BLUE is a quadrilateral.
To prove: Quadrilateral BLUE is a parallelogram.
Proof: By the definition of parallelogram, the opposite sides of the parallelogram are equal and parallel.Thus, we have to prove that the opposite sides of quadrilateral BLUE are equal and parallel.
Now, (BL and EU) and (BE and LU) are the opposite sides of the parallelogram BLUE, thus all we need is to prove that BL║EU ..
Therefore, Option A is correct.
Answer and explanation:
Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%
Cable TV cost increased by 21.818% of original cost
Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%
Dozen of eggs cost increased by 22.636% of original cost
Therefore both customers can't be correct, cost of a dozen of eggs increased the most.
