The isosceles triangle has a perimeter of 7.5 m. Which equation can be used to find the value of x if the shortest side
2 answers:
Answer:
<u>(7.5-2.1) /2</u>
<u>If the shortest side measures 2.1 m </u>.
<em>7.5-2.1 =5.4.</em> Then divide by 2 each side is 2.7m
Answer:
The equation for finding the value of x is 2x + 2.1 = 7.5 and the value of x is 2.7 m.
Step-by-step explanation:
Perimeter of the isosceles triangle = 7.5 m
Length of the shortest side = 2.1 m
Let the length of each of the other sides of the triangle = x meter
Then the equation for the perimeter of the triangle becomes:
Sum of 3 sides f the triangle = 7.5 m
=> 2*x + 2.1 = 7.5
=> 2*x = 7.5 - 2.1 = 5.4
=> x = 5.4/2 = 2.7 m
So the relevant equation for finding the value of x is 2x + 2.1 = 7.5 and the value of x is 2.7 m.

Answer:
Step-by-step explanation:
-6.25x > -38 3/4
-6.25x > -155/4
Multiply by (-4)
25x > 155
divide by 25,
x > 155/25
x > 31/5
x > 6.2

3/4 To find the slope of a line you need to do rise/run. you find two solid points meaning find two points are exactly on a intersection. Then you count up how much it needs to the point then count across to the next point
