Answer:
See below.
Step-by-step explanation:
x-7≤3x+1
+7 +7
x≤3x+8
-3x -3x
-2x≤8
/-2 /-2
x≥-4
The inequality symbol reverses when divided/multiplied by a negative term.

Let x be the degree of angle a.
Angle b: 20+3x
Angle c: 55+x
We know that all angles add up to 180 degrees.
180=x+(20+3x)+(55+x)
180= 5x+75
180-75=5x
105/5=x
21=x
Angle a: 21 degrees
Angle b: 20+3(21) => 83 degrees
Angle c: 21+55 => 76 degrees

43.
The coefficient of something is the numerical value in that term. For example, if we have 4x. The coefficient is 4.
Hey there
1 km = 1000 meters
So 5 km will equal 5000 meters
.1 will equal 100 meters
5.1 km = 5100 meters
<span>100,000 centimeters = 1 kilometer
</span>5.1 km = 510000 centimeters
Hope this helps
