Step-by-step explanation:
the first one if you are solving for x it will be x=21-8y
if you are solving for y it will be y =21/8 - x/8
the second one will be if you are solving for x x = 2 -5y/3
solving for y is y=6/5-3x/5
Answer:
x=(-60)
Step-by-step explanation:
x/2-12=(-42)
add 12 to -42
x/2=(-30)
divide -30 by 1/2
x=(-60)

The following is an example of a cluster sampling.
Cluster sampling<span> is a </span>sampling<span> technique used when "natural" but relatively heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this technique, the total population is divided into these groups (or </span>clusters) and a simple randomsample<span> of the groups is selected.</span>
Answer:
(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.
Step-by-step explanation:
In the coordinate plane, an angle is said to be in standard position when its value is stated with respect to the x-axis.
Therefore, for an angle to be in a standard position, one of its rays must be on the x-axis.
From the given options, only Option C has a ray that sits on the x-axis. Therefore, it is the only angle in standard position.
