The answers to the first two systems of equations
The number of partial products Alan will have when he multiplies a 4-digit number by 36 is; 8 partial products.
First, we must establish that a 4-digit number will have 4 place values namely;
- Thousands
- Hundreds
- Tens
- Ones.
And since, 36 has 2 place values;
We can conclude that the number of partial products that Alan wil have is; 2× 4 = 8.

Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
Tan(30deg) = n/rt(3)
1/rt(3) = n/rt(3)—> n=1
sin(30deg) = 1/m
1/2=1/m—> m=2
Thus m=2 ,n=1
