The equation is 20x = 1200
x=1200÷20
x=60 rows
Answer:
might be 8.4
Step-by-step explanation:
..............
3/5=12/20. 1/4=5/20. 3 12/20+2 5/20= 8 17/20
X=12y there is no conventional way of solving precisely.
To solve the set of equations given above, we can use the substitution
method where we substitute one equation to the other and solving for one
variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
<span>Therefore, the correct answer from the choices is option A, (5,0).</span>
