Awnser please :((((((((((((((((((((
vfiekz [6]

Answer:

I believe it is: 6n+8+7y+4m

Step-by-step explanation:

You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables.  Since the top and bottom are the same, you just list it once.  Sorry, not the best explanation.  Please let me know if I am wrong.  It's been a while since I had to any type of algebra.

2. The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers aj set up the variables (2
storchak [24]

Answer:

Larger number = 34

Smaller number = 17

Step-by-step explanation:

Given that:

Sum of numbers = 51

Let,

x be the larger number

y be the smaller number

According to given statement;

x+y=51       Eqn 1

x = 2y        Eqn 2

Putting x=2y in Eqn 1

2y+y=51

3y=51

Dividing both sides by 3

\frac{3y}{3}=\frac{51}{3}\\y=17

Putting y=17 in Eqn 2

x=2(17)

x=34

Hence,

Larger number = 34

Smaller number = 17

5.8 km is how many meters
stepan [7]

Answer:

5,800m

Step-by-step explanation:

1 km = 1000 m

Use the SBD (small to big, divide) and BSM (big to small, multiply) method.

So, 5.8 X 1000, as we are converting km(big) to m(small) and move the decimal point corresponding to the number of zeroes = 5800m
