Answer:
n = 135 m = 45
Step-by-step explanation:
N is 135 and m is on a strait line (180) so if you do 180 - 135 you will get the answer for m.
Hope this helped.
Answer: (5,8)
Step-by-step explanation:
So this is a matter of using a system of linear equations
To start if a total of 13 people got a ticket then we know that
x+y=13
x and y being explained in the problem
then if adult tickets are $40 and children tickets are $20 and the total cost is 360 we can set up the next equation
40x+20y=360
<em>If you were to plug in 1 lets say into x that means that 1 person bought a ticket for $40 this shown by 40 (1) this is the same premise for the childrens tickets.</em>
now we have
x+y=13
40x+20y=360
now we can solve by eliminating one of the variables this is done by either getting rid of the x or y and solving for the other. I solved for the y value first this looks like
-40(x+y=13)
40x+20y=360
Distribute the -40 to each value
giving you
-40x-40y=-520
40x+20y=360
add these together from the top down
the x's cancel leaving
-20y=-160
then isolate the y value by dividing both sides by -20
-20y/-20=-160/-20
leaving you with your y point
y=8
This is how many childrens rickets were sold now we can plug into the first linear equation
x+8=13
now easy subtration to isolate the x point
x+8-8=13-8
x=5
Finally leaving you with point (5,8)
Answer:
<h2>The length of the pieces is 3 inch, 6 inch and 13 inch.</h2>
Step-by-step explanation:
Let, the length of the first piece is x inch.
Hence, the length of the second piece is 2x.
It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.
The total length of the steel is 22 inch.
Hence, x + 2x + 4x + 1 = 22
or, 7x = 21
or, x = 3.
The length of the second piece is 6 inch.
The length of the third piece is 13 inch.
