Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5). Step 2: Choose another point on the line, such as (1, 3).Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is. Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio of the slope. Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

In how many different ways can 3 identical green shirts and 3 identical red shirts be distributed among 6 children such that each child receives a shirt

Answers

Answer:

Total number of ways will be 20

Step-by-step explanation:

We have given three identical green shirts and three identical red shirts

So total number of shirts = 3+3 = 5

We have to distribute these shirts to 6 children so that each children got one shirt

Number of ways will be equal to $=(6!)/(3!3!)=20$ ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )

Peter has 18 dimes. He uses 12 dimes to buy a drink. The number of dimes he has left is one half the number of pennies he has. How many pennies does Peter have? Write an equation to solve the problem. Please help!

Answers

p=(18-12)2
p=pennies remaining
p=12

Final answer:

The problem can be solved by setting up and solving an equation based on the number of coins - specifically dimes and pennies. After Peter spends some of his dimes, the remaining dimes are half the number of his pennies. From this, we can find out that Peter has 12 pennies.

Explanation:

The subject of this question is Mathematics, specifically, it focuses on solving word problems, and in this case, the problem relates to coins - dimes and pennies. From the problem, we know that Peter starts with 18 dimes and he spends 12 dimes, he will be left with 18 - 12 = 6 dimes.

The problem also states that the number of pennies Peter has is twice the number of dimes. Therefore, we can write this as an equation: 2 × (Number of dimes) = Number of Pennies.

Substituting the number of dimes (6), the equation become: 2 × 6 = Number of Pennies. Solving this equation, Peter has 2 × 6=12 pennies.
