They are the same angle in the obtuse triangle and same points but mixed up proof: you can highlight the lines and make points for the letters w x and y hope this helps :)
Answer:
$6.30
Step-by-step explanation:
First, get the volume of the cereal box with the equation V = lwh.
V = 7(3)(10) = 210 cubic inches
Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.
.03(210) = $6.30
In the given question, it is given that, the cost of telephone call, s, is $0.75 plus $0.25 times the number of minutes .
And we have to put the given informationin algebraic expression .
For the cost of telephone call, we have to use s and for the number of minutes, we need to use t .
So the required expression is
Answer:
The first equation should be multiplied by 9 and the second equation by −4
Step-by-step explanation:
Given the simultaneous equation
First Equation: 5x − 4y = 28
Second equation: 3x - 9y = 30
In order to eliminate y, we must make the coefficient of x in both expression to be equal.
To do that the first equation should be multiplied by 9 (negative value of the coefficient of y in equation 2)and the second equation by -4( (coefficient of y in equation 1)
