Answer:
20
Step-by-step explanation:
2(a+3b)=2(10)
If you would like to solve blank of 100 equals 16%, you can calculate this using the following steps:
x of 100 equals 16%
x * 100 = 16%
x * 100 = 16/100 /100
x = 16/100 / 100
x = 0.0016
The correct result would be: 0.0016 of 100 equals 16%.
Answer:
Option D.
Step-by-step explanation:
Consider the below figure attached with this question.
If a line passes through two points
and
, then the equation of line is

From the below figure it is clear that the a solid line passes through the points (-2,0) and (0,4). So, the equation of related line is




All area above the solid line is shaded. It means the sign of inequality is ≥.

From the below figure it is clear that the a dashed line passes through the points (2,0) and (0,2). So, the equation of related line is




All area below the dashed line is shaded. It means the sign of inequality is <.

System of inequality is


Therefore, the correct option is D.
for
x
y
: To do this we must divide each side of the equation by
2
y
which will give us
x
y
while keeping the equation balance.
