Answer:

Elimination

Step-by-step explanation:

Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.

Which equation can be represented using the number line?​
frez [133]

Answer:

First Equation: \frac{3}{4} \div \frac{1}{8} =6

Step-by-step explanation:

From the given number line we can see that there are 6 arrows/jumps of equal sizes to reach from 0 to \frac{3}{4}

Each small jump is equivalent to \frac{1}{8}. This is because from 0 to \frac{1}{4} there are 2 jumps, so 1 jump will be equal to \frac{1}{4} divided by 2 which is equal to \frac{1}{8}

From 0 to \frac{3}{4}, 6 jumps of \frac{1}{8} are made. In other words we can say \frac{1}{8} is added to itself 6 times to reach to \frac{3}{4}.

Adding \frac{1}{8} 6 times to itself also means multiplying \frac{1}{8} by 6. So we can set up the equation as:

\frac{1}{8} \times 6 = \frac{3}{4}

Dividing both sides by \frac{1}{8}  we get:

6=\frac{3}{4} \div \frac{1}{8} \\\\ or\\\\ \frac{3}{4} \div \frac{1}{8} =6

Hence, the first equation represents the given number line.

Slope = rise over run = the change in y over the change of x
if you want it to be exactly 2, then you have to make sure the equations are proportional.
 -5 - y / 6-1
so you simplify it -5-y/ 5
the answer needs to be 2 times 5,
2 x 5 = 10, so you need to add 5 because that's what you subtract from it in the end.
y = 15

David has 85 white eggs and 28 brown eggs. He puts 6 eggs into each tray and fills as many trays as he can. How many eggs are le
Murljashka [212]

Answer:

5 eggs are left over.

Step-by-step explanation:

Computers love this question. They have a built in command called mod which will give the answer in one line.

L = (85 + 28) mod 6: Print L

Humans have a little tougher time with it. We do it like this

Add 85 and 28 = 113

Divide by 6

113 / 6 = 18.8333333

What is left over is 0.833333333. But what does that mean, and how do you get rid of it?

Answer Number of Trays: The 18 is easily explained. He can fill 18 trays.

But we still have 0.83333333 to deal with.

The simplest way is to multiply that by 6.

6 * 0.833333333 = 5

The answer is 5
