-2x + 5 = -1
subtract 5 from both sides: -2x = -6
divide each side by -2: x = 3
plug in 3: 5(3)
multiply: 15
the value of 5x is 15.
Answer:
its either d or a
Step-by-step explanation:
Answer:

Step-by-step explanation:
An isosceles ∆ has 2 equal sides. The perimeter of a ∆ is the sum of all its sides.
Given that the perimeter of the triangle above is "at least 137 ft", this means the sum of all its sides is equal to or greater than 137 ft.
Thus, using inequality, this can be represented as:

Solve for x

Add like terms

Subtract 17 from both sides


Divide both sides by 8


Step-by-step explanation:
X+3X+90=360
4X+90=360
4X=360-90
4X=270
270÷4=67.5
X=67.5 degrees
-7x2p= -14p
-7x-4k= 28k (negative x negative = positive
-14p+28k=....
2xp=2p
2x1=2
-14p+28k+2p+2
(-14p+2p) +28k+2
-12p+28k+2
or
28k-12p+2
