Answer: x=7

Step-by-step explanation: In the given figure M is a midpoint .By definition of midpoint AM=MD.It is given AB=CD in figure. Two of the sides are equal .to prove the triangles to be congruent by SSS the third side must be equal

That is BM=CM,

Or 4x-1=3x+6

Subtracting 3x both sides

4x-3x-1=3x-3x+6

x-1=6.

Adding 1 both sides

x=7.

x=7 will make the third side equal and hence the triangles will be congruent by SSS.

Answer:

549

Step-by-step explanation:

A calculator can give you an equivalent expression.

I might work from the middle outward:

= 486 -3 +33×2

= 483 +66

= (480 +60) + (3 +6)

= 540 + 9

= 549

how many cubic blocks of side length 1/6 inch would take to fill a rectangular prism with a length, width, and height of 1/3 inc

borishaifa [10]

Volume of one cubic block = (1/6)^3 = 1/216 cu ins

Volume of the prism = 1/3 * 2/3 * 2/3 = 4/27 cu ins

Number of blocks to fill prism = 4/27 / 1/216 = (216*4) / 27 = 32

1/4(r-5/2)=1/8 i need an answer cant figure it out

san4es73 [151]

1/4(r - 5/2) = 1/8
Divide both sides by 1/8 :0
2(r - 5/2) = 1
r - 5/2 = 1/2
r = 1/2 + 5/2 = 6/2

r = 3 Answer
