6 1/8 = 49/8
8x6=48+1=49
4 2/5 = 22/5
5x4=20+2=22
49/8+22/5
lowest common denominator=40
49x5=245/40
22x8=176/40
245+176= 421/40
421/40= 10.5 rounded down is 10
40x10= 400
421-400=21
10 21/40
whole number factors of 21- 1,3,7,21
whole number factors of 40- 1,2,4,5,8,10,20,40
HCF= 1
1(21)/1(40)
= 10 21/40
OR
6+4=10
1/8+2/5
5/40+16/40
=21/40
10 21/40

In the figure below,S is between Q and T and R is the midpoint of QS. If RS=4 And RT= 12 find QT​
Oxana [17]
Qt = 16.

Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line

If a is an odd integer and b is an even integer, which of the following makes an odd integer?
Serga [27]

9514 1404 393

Answer:

  D.) a+2b

Step-by-step explanation:

The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...

  A) 3(0) = 0 . . . even

  B) 1 +3 = 4 . . . even

  C) 2(1+0) = 2 . . . even

  D) 1 +2(0) = 1 . . . odd

_____

<em>Additional comment</em>

These rules apply to even/odd:

  • odd × odd = odd
  • odd × even = even
  • even × even = even
  • odd + odd = even
  • odd + even = odd
  • even + even = even

Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.

Is the following expression true or false? Show your work.
Paul [167]

Answer: True

Solution:

Rearrange the equation to the LHS:

[x^2 + 8x + 16] · [x^2 – 8x + 16] - (x^2 – 16)^2 = 0

Factoring  x^2+8x+16

x^2 - 4x - 4x - 16

= (x-4)  •  (x-4)

= = (x+4)2

So now we have an equation

(x + 4)^2 • (x - 4)^2 -  (x^2 - 16)^2  = 0

Step 2: Evaluate the following:

(x+4)2   =    x^2+8x+16

(x-4)2   =    x^2-8x+16  

(x^2-16)2   =    x^4-32x^2+256

(x^2+8x+16)  (x^2-8x+16  ) -  (x^4-32x^2+256 )

0 = 0

Hence True
