Answer:
Option B - graphing is the correct answer.
Step-by-step explanation:
To solve a system of inequalities we need graphing. Inequality tells us about the relative size of two values. When we graph the x and y co-ordinates, the solution is not the drawn line, but the area of the coordinate plane that satisfies the inequality. In inequalities, multiple solutions can be possible.
Plug and chug method does not a complete solution, it only tells where a point belongs. Guess and check does not apply here.
If your friend now has 18 that means you had 48, as mentioned above, you had given half of your tokens, half of 48 is 24. =24
Answer:
Strong positive correlation
Step-by-step explanation:
The closer the value of ρ is to +1, the stronger the linear relationship. For example, suppose the value of oil prices are directly related to the prices of airplane tickets, with a correlation coefficient of +0.8.
The expression obtained after solving the given expression is,![\rm \frac{(15x+3)}{y}](https://tex.z-dn.net/?f=%5Crm%20%5Cfrac%7B%2815x%2B3%29%7D%7By%7D)
<h3>What is a BODMAS rule?</h3>
For the Bracket, Order, Division, Multiplication, Addition, and Subtraction rules, BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction.
Given expression ;
9(5x + 1) ÷ 3y
Follow the BODMAS rule;
Step 1; Divide
![\rm \frac{9(5x+1)}{3y} \\\\ \frac{3(5x+1)}{y} \\\\](https://tex.z-dn.net/?f=%5Crm%20%5Cfrac%7B9%285x%2B1%29%7D%7B3y%7D%20%5C%5C%5C%5C%20%5Cfrac%7B3%285x%2B1%29%7D%7By%7D%20%5C%5C%5C%5C)
Step 2; Multiply
![\rm \frac{9(5x+1)}{3y} \\\\ \frac{(15x+3)}{y} \\\\](https://tex.z-dn.net/?f=%5Crm%20%5Cfrac%7B9%285x%2B1%29%7D%7B3y%7D%20%5C%5C%5C%5C%20%5Cfrac%7B%2815x%2B3%29%7D%7By%7D%20%5C%5C%5C%5C)
Hence the expression obtained after solving the given expression is,![\rm \frac{(15x+3)}{y}](https://tex.z-dn.net/?f=%5Crm%20%5Cfrac%7B%2815x%2B3%29%7D%7By%7D)

Let x = the number of penguins we are finding
x ÷ 100 × 30 = 15
x = 15 ÷ 30 × 100
x = 50
hope this helps and have a great day :)
