(You could do this shorter, but by the time i realized that it was too late.)
First, we need one of the variables (x or y) to have the same coefficient.
Lets use the variable y, since it uses smaller numbers.
Multiply the first equation by the denominator of y, which is 3. Then multiply the second equation by the denominator of y in the second equation, which is 4.
You get:
1st equation:
2nd equation:
Now we need to multiply the first equation by 3, so we can have "3y" in both of the equations.
1st equation: 9/2x + 3y = 81
2nd equation:
Now we can subtract both of the equations.
12/5x + 9/2x = 69 We need to make the common denominator for x.
24/10x + 45/10x = 69
69/10x=69
x=10
Now we substitute x into the first equation (or the second, doesn't matter).
1/2 * 10 + 1/3y=9
5 + 1/3y = 9
1/3 y = 4
y = 12
Yes. Translation is taking an object and sliding it across something. :)
Answer:
18-n: when n=6 the value is 12
Step-by-step explanation:
You are looking for the difference so automatically b and c are out. 18-6 is 12 not 24.
The ration of the number of cookies to the pastries in a box is which table shows
It is given in the question that,
Hawthorne Lane bisects the angle formed by Melville Road and Emerson Avenue. And the angle formed by Melville Road and Emerson Avenue is 119°.
Therefore angle formed by Melville Road anf Hawthorne Lane equals to angle formed by Hawthorne Lane and Emerson Avenue equals to
half of 119 = 59.5 degree.
And Dickinson Drive bisects the angle formed by Emerson Avenue and Thoreau Street. The measure of the angle formed by Emerson Avenue and Thoreau Street is 134°.
Therefore angle formed by Emerson Avenue and Dickinson drive equals to angle formed by Dickinson drive and Threau Street equals to half of 134 that is 67 each .
Hence the angle formed by Hawthrone Lane and Dickinson Drive is the sum of 59.5 and 67.That is
