Can anyone help and explain how to do this it’s very confusing?

Answer:

Find the slopes; 123 servings

Step-by-step explanation:

When you look at the graph and table, find out which ones have a slope of 1/2

To find slope you have to use this equation

$\frac{y - y^1}{x - x^1}$

So for each graph and table, calculate the slope using that formula :)

For the second question,

For every 10 students, the amount of juice dispensed was

7*4 + 3*8 = 52

So divide 52 by 10 to get 5.2

Then divide the total amount of juice (640) by 5.2 and that rounds to about 123 servings of juice

Evaluate.<br><br> 21 ÷ 7 + 20 • 102 • 2 – 3

mrs_skeptik [129]

To avoid confusion, remember PEMDAS. This is the order of operation.
Parenthesis, Exponents, Multiply, Divide, Add, Subtract

21 ÷ 7 + 20 * 102 * 2 - 3

No parenthesis and no exponents, proceed to multiplication.

20 * 102 * 2 = 4,080

Then, perform division

21÷7 = 3

Then, do addition

3 + 4080 = 4083

Lastly, do subtraction

4,083 - 3 = 4,080

So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080

What is 100 in decimals

lesya [120]

Answer:

Step-by-step explanation:

I am assuming you mean what is 100 % in decimals. To convert a percent to a decimal, you divide by 100 (percent means by 100). If you divide 100 by 100, you get 1.
