Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even.
m=2k-n, p=2l-n

Let m+n and n+p be even integers, thus m+n=2k and n+p=2l by definition of even
m+p= 2k-n + 2l-n substitution
= 2k+2l-2n
=2 (k+l-n)
=2x, where x=k+l-n ∈Z (integers)
Hence, m+p is even by direct proof.

6.2 x 10^-3 Because when you add them together you get .0062 so you don't want anymore than one number to the left of decimal when in scientific notation therefore its 6.2 so you wanna move the decimal three spaces to the left to get .0062 therefore its 6.2x10^-3

Please help due tmrw
Wewaii [24]

Answer:

1. w = 3l

2. k = 1/2 * b

Step-by-step explanation:

1.  w = 3l

   w = width     l = length

   Since we are solving the equation for the width, we can make the equation w = ? for now. since the width is equal to three times the length, we can make the equation w = 3l.

2. k = 1/2 * b

   k = kool-aid     b = beef    

   Since we are solving the equation for the kool-aid, we can make the equation k = ? for now. since the kool-aid is equal to half the beef sold, we can make the equation k = 1/2 * b

I hope this helped and please mark me as brainliest!

Jack charges $40 initial fee plus $30 an hour to work on vehicles. Mark charges $25 an hour with a $50 initial fee. to work on v
joja [24]

Answer:

Step-by-step explanation:

A.)

Let the equal number of hours be represented by variable h;

The two equations will be as follows;

Jack; 40 +30h

Mark; 50 +25h

Next, equate them;

40 + 30h= 50 + 25h

30h - 25h = 50 - 40

5h = 10

h =10/5

h = 2

Therefore, they charge the same amount at 2 hrs.

B.) The amount charged;

Replace the variable H in any of the two equations above with 2 to solve for the amount.

Equation 40+30h = 40 + (30*2)

=40 + 60

= $100
