5 + 2(2) = 5 + 4
5 + 4 = 9
The solution is 9
<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>
Yes, they intersect at the coordinates (1,13) and (2,10)
Expected value equals sum of the product of each value and its possibility.
a.
1/2×75%+1/4×25%=0.4375
the expected value of grass growth for the day is 0.4375
b.
0.4375×31=13.5625
the expected value of grass growth for the month of july is 13.5625
