Answer:
The value of 'x' is 1 and 'y' is 2. So, the point is (1, 2).
Step-by-step explanation:
Given:
The given pair of linear equations are:
In order to solve by elimination method, we have to eliminate any one variable using mathematical operations. Let us eliminate 'y'.
Multiplying the first equation by 2 and adding the result to the second equation. This gives,
Now, the value of 'y' can be calculated by plugging in 1 for 'x' in the first equation. This gives,
Therefore, the value of 'x' is 1 and 'y' is 2.
The solution is (1, 2).
Answer:
3/10
Step-by-step explanation:
- add 7+4+6+3=20
- the take how many times both coins landed on heads which is 6 and put the 6 over 20
- then divide by 2 because 2 can go into both 6 and 20
- and you end up with 3/10 which you can't simplify any more.
Hello!
To solve this, find the cost of a single light bulb first, by dividing 9 / 5.
9 / 5 ==> 1.80
One light bulb is $1.80
Now, multiply 1.80 by 7.
1.80 * 7 = 12.6
7 light bulbs cost $12.6
Hope this helps! ☺♥
Answer:
Man your old lol
Step-by-step explanation:
since the diameter of the base of the cylinder is 6 feet, then its radius is half that, or 3 feet.
![\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=3\\ h=9 \end{cases}\implies V=\pi (3)^2(9)\implies V=81\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Bvolume%20of%20a%20cylinder%7D%5C%5C%5C%5C%0AV%3D%5Cpi%20r%5E2%20h~~%0A%5Cbegin%7Bcases%7D%0Ar%3Dradius%5C%5C%0Ah%3Dheight%5C%5C%5B-0.5em%5D%0A%5Chrulefill%5C%5C%0Ar%3D3%5C%5C%0Ah%3D9%0A%5Cend%7Bcases%7D%5Cimplies%20V%3D%5Cpi%20%283%29%5E2%289%29%5Cimplies%20V%3D81%5Cpi)
