Answer:
x = 6 , y = -2
Step-by-step explanation:
2 x + 3 y = 6 (Equation 1)
x + y = 4 (Equation 2)
<u>Solving by substitution</u> :
(Equation 2) ⇒ y = 4 - x
<u>Substitute y by 4 - x in (equation 1)</u> :
2 x + 3 (4 - x) = 6
Then
2 x + 12 - 3x = 6
Then
12 - x = 6
Then
12 - 6 = x
Then
x = 6
<u>We obtain</u> :
y = 4 - x and x = 6
Then
y = 4 - 6
= -2
Answer:
When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet. Some substances can be magnetized by an electric current.
Step-by-step explanation:
Answer: Jacob's second jump was 6 1/3 feet
Step-by-step explanation:
On his first jump, he jumped 7 2/3
feet. We would convert each mixed fraction to improper fraction
to enable easy addition and subtraction. Converting 7 2/3 feet to improper fraction, it becomes 23/3 feet.
His second jump was 1 1/3 feet shorter. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet.
Therefore, the distance that Jacob covered on his second jump would be
23/3 - 4/3 = 19/3 feet
Converting 19/3 feet back to mixed fraction, it becomes
6 1/3 feet
