7+10x-2x-2=-3
—-Combine like terms...10x-2x=8x and 7-2=5
8x+5=-3
——subtract 5 on both sides.. the 5’s will cancel each other and -3-5=-8
8x=-8
——Divide 8 on both sides...the 8’s will cancel out and -8 divided by 8 = -1
Answer: x = -1
Answer:
6 units long.
Step-by-step explanation:
Given:
A polygon drawn on a graph.
In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.
Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.
Coordinates of A are 
as seen in the graph.
Coordinates of B are 
as seen in the graph.
Now, distance formula for two points 
is:
Therefore, the horizontal line at the top is 6 units long.
Answer:
Mr X
Step-by-step explanation:
his identity is a variable ; it could be anybody of the male gender.
all the other ones denote known designations, i.e, B+ grade
40/1.4=28.57 i think this is right
Sales above monthly quota = 23800 - 17000 = $6800
So her commission = 0.05 * 6,800 = $340
Therefore her total salary for the month = 3600 + 340
= $3,940 (answer).
