The sum of three consecutive even numbers is 48. what is the largest of these numbers?
shutvik [7]
Let's name the three consecutive even numbers n, n+2, and n+4. We know that their sum will be divisible by 2 because they are all even, so we can set x = n/2, and say that x + x+1 + x+2 = 48/2 = 24. Then, we can solve for 3x + 3 = 24, 3x = 24-3 = 21, and x = 21/3 = 7.
Final answer: n/2 = 7, so n = 14, so n+4 (the greatest number) is 14+4 =

Find the solution of the following system of equations -5+2y=9 3x+5y=7
Rudiy27

Answer:

x=-\frac{28}{3}\\\\y=7

Step-by-step explanation:

Given the system of equations:

\left \{ {{-5+2y=9} \atop {3x+5y=7}} \right.

You can pply Substitution method:

First you must solve for "y" from the first equation:

-5+2y=9\\\\2y=9+5\\\\2y=14\\\\y=\frac{14}{2}\\\\y=7

Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

3x+5(7)=7\\3x=7-35\\\\x=-\frac{28}{3}

What is the slope of the line represented by the equation y=x/3-5
Nana76 [90]

Answer:

a. 1/3

Step-by-step explanation:

y=x/3-5  (rewrite x - term)

y = (1/3) x + 5

recall that in the slope-intercept form of  a linear equation y = mx + b

m is the slope.

In our case, we can clearly see that slope  m = (1/3)
