Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
Answer:
Naman is 12 years old
Step-by-step explanation:
This means his sister is 3 which means in 20 years Naman will be 32 and his sister will be 23. Double 23 and you get 46 and 46 - 32 is 14
Answer:
c cylinder
Step-by-step explanation:
I think the answer is 3/9 because there is 9 students running but only 3 of them win medals so I think it would be 3/9 or maybe something else
If you would like
to write the following in the math expression, you can do this using these
steps:<span>
<span>a number ... </span>n
eight less than four times a number ... 4 * n - 8</span>
<span>
is less than 56 ... < 56
4 * n - 8 < 56
4 * n < 56 + 8</span>
<span>4 * n < 64 /4</span>
<span>n < 64 / 4</span>
<span>n < 16</span>
The possible values of that number are less than 16.
