Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
2x - 3y = - 2 → (1)
4x + y = 24 → (2)
Multiplying (1) by - 2 and adding to (2) gives
- 4x + 6y = 4 → (3)
Add (2) and (3) term by term
(4x - 4x) + (y + 6y) = (24 + 4), that is
7y = 28 ( divide both sides by 7 )
y = 4
Substitute y = 4 into either of the 2 equations
Substituting y = 4 into (2)
4x + 4 = 24 ( subtract 4 from both sides )
4x = 20 ( divide both sides by 4 )
x = 5
Thus the answers x = 5 and y = 4 are the same as her first method
Answer:
x=24
Step-by-step explanation:
The opposite angles are equal as per certain theorems.
3x-1=71
3x=72
x=24
Answer:
(3, -2)
Step-by-step explanation:
The <em>midpoint</em> of two points is half-way between the x-values and the y-values.
The formula is
M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
For the points (5,-5) and (1,1),
Half way between the x values is
(x₁ + x₂)/2 = (5 + 1) /2 = 6/2 = 3
Half way between the y values is
(y₁ + y₂)/2= (-5 + 1)/2 = -4/2 = -2
M = (3, -2)
The graph below shows your two points at (5,-5) and (1,1) and the mid-point at (3, -2).
The answer would be 850 milliliters.
