If Juliana and Brody hiked 3 2/3 trail and 2 5/6 trail how far did they hike

Mathematics

Part of trail hiked by Juliana = 3 \frac{2}{3}

Part of trail hiked by Brody = 2 \frac{5}{6}

We have to calculate that how part did they hike.

Total part of the trail hiked by Juliana and Brody is calculated by adding the part of trail hiked by them individually.

So, total distance traveled

= 3 \frac{2}{3} + 2 \frac{5}{6}

= \frac{11}{3} + \frac{17}{6}

LCM of 3 and 6 is 6.

= \frac{22+17}{6}

= \frac{39}{6}

= \frac{13}{2}

= 6 \frac{1}{2}

So, Juliana and Brody traveled 6 \frac{1}{2} far.

Solve for y.<br> 6 = 2 (y+2)
Ad libitum [116K]
Start by dividing both sides by two to get 3 = y + 2. then subtract two from both sides to get y = 1.

If the operation is defined for all integers a and b by <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail=
leva [86]

Answer:

(E) I, II and III

Step-by-step explanation:

Given,

[email protected] = a + b - ab ∀ a, b ∈ Z ( set of all integers ),

For solving this question we need to remember the following properties of integers:

  • Commutative property of addition
  • Additive identity property of addition
  • Commutative property of multiplication
  • Distributive property of multiplication over addition

I. [email protected] = a + b - ab,

[email protected] = b + a - ba = a + b - ab

Thus, [email protected] = [email protected]

II. [email protected] = a + 0 - a × 0

= a + 0 - 0  

= a

III. ([email protected])@c = ([email protected])+c - ([email protected])c

= (a + b - ab) + c - (a + b - ab)c

= a + b - ab + c - ac - bc + abc

= a + b + c - ab - bc - ac + abc,

Now, [email protected]([email protected]) = [email protected]( b + c - bc )

= a + (b + c - bc) - a(b+c - bc)

= a + b + c - bc - ab - ac + abc

= a + b + c - ab - bc - ac + abc.

Thus, ([email protected])@c = [email protected]([email protected])

We have a right triangle with legs of 6 and 8. The hypotenuse is unknown so let it be x for now

Plug these three values
a = 6
b = 8
c = x
into the Pythagorean Theorem below. Then solve for x

a^2 + b^2 = c^2
6^2 + 8^2 = x^2
36+64 = x^2
100 = x^2
x^2 = 100
sqrt(x^2) = sqrt(100) ... apply the square root to both sides
x = 10

The final answer is 10 ft. This option isn't listed which makes me think your teacher made a typo somewhere.
