the lengths of the sides of a triangle are x, x - 5, 3x centimeters. if the perimeter is 80 centimeters, what is the value for x
?
1 answer:
Answer:
x= 17cm
Step-by-step explanation:
given:
sides of a triangle:
x, x-5, 3x
perimeter= 80cm
perimeter of a triangle= side + side + side
80 = x + (x-5) + (3x)
80 = x + x + 3x -5 ------------->(rearranging the like terms together)
80 = 5x - 5
80+5 = 5x
85 = 5x
85/5 = x
17cm = x

Answer: I am pretty sure it is y=-1/4x-8. Hope this helps!
Step-by-step explanation:subtract the 2x from both sides which gives you 8y=-2x-64. Then you want to divide both sides by 8 to get y=-1/4x-8
Answer:
It is the third answer
Step-by-step explanation:
Answer:
y-8=1/2(x-10)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-8)/(4-10)
m=-3/-6
simplify
m=1/2
y-y1=m(x-x1)
y-8=1/2(x-10)
