Write 3x+4y=58 and 1x+3y=36 using elimination

Mathematics
1 answer:
Triss [41]4 years ago
5 0
DENOTING
Eqn 1: 3x+4y=58
Eqn 2: 1x+3y=36

TRANSLATING
(Multiply Eqn 2 by 3)
Eqn 3: 3x+9y=108

ELIMINATION
(Subtract Eqn 3 from Eqn 2)
Eqn 4: -5y=-50

Divide both sides by -5 to derive the value of y.
y=10

SUBSTITUTION
(Substitute the value of y to any of the first two equations)

3x+4(3)=58
3x=58-12
3x=46
x=46/3 or 15 1/3

Find the coordinates of the midpoint of AB given A (2,3) and B (4, -2)
marshall27 [118]

Answer:

(3, 1/2)

Step-by-step explanation:

The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3.  The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.

Thus the midpoint of AB is (3, 1/2).

Find the value of x and y. Need some help solving this one.
Oksi-84 [34.3K]

Answer: x is 45, y is 80

Step-by-step explanation:

subtract the angles surrounding x (70 - 25 = 45)

add 45 + 55 to get 100
the entire triangle has to equal 180 degrees, so subtract 100 from 180 to get the value of y
