Make the coefficient of y the same in both equations:
To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).
14x + 10y = 38
-35x - 10y = -80
Eliminate the y variable by adding the equations from each other
(14x + 10y = 38)
+ (-35x - 10y = -80)
= -21x + 0y = -42
We now have -21x = -42. The y variable has been eliminated.
Solve for x
-21x = -42
Divide both sides by -21 to get x on its own.
x = 2
Substitute x into the equation to find y.
7*2+5y=19
14+5y=19
Subtract 14 from both sides.
5y=19-14
5y=5
Divide by 5 on both sides to get y on its own.
y=5/5
y=1
The answer is (2,1)
Answer:
It SHOULD be 527.79(m2) If I'm not mistaken.
Step-by-step explanation:
The degree is 4, because it has 4 zeros.
For the distributive property, multiply the number outside the parentheses by each term inside the parentheses.
1/6 x 12s = 2s
1/6 x 6 = 1
Now combine them to get the final answer: 2s + 1
Answer:
d) The probability spinner will land on black all three times is 1/8
Step-by-step explanation:
The probability of landing on black = 1/2
The probability of landing on red = 1/3.
Now, if the spinner is spun 3 times.
The probability it will land on black all three times
= 
= 
Hence, the probability spinner will land on black all three times is 1/8.
