Hi! i need help (It is due in a few hours)

Mathematics

Answer:

1a and 2a

Step-by-step explanation:

<em>In the first one, </em>you should write an expression to help you picture what is happening. Since a test score is 4 times a quiz score which is x, a test score will be 4x. And since there are also 2 quizzes we should do 2x or just x + x. We then add the test score points and the quiz score points.

Here is the first way:

4x + 2x = 6x

Here is the second way:

4x + x + x = 6x

6x is your answer!

<em>In the second one, </em>you should also write an expression. Since a novel costs 6 more than a textbook which is represented by x, we will represent it the cost of a novel like this: x + 6. And since there is also one textbook we will just mark that as x. Now all we need to do is add them up/

This is what it will look like:

x + 6 + x = 2x + 6

2x + 6 is your answer!

I hope this helped! Please give Brainliest.

How would you teach something you have learned this year in Math to someone younger than you? Write more than 5 sentences
rewona [7]

Answer:

ok here ya go

Step-by-step explanation:

A way that I would teach someone something that I learned in math this year to someone else is simple. I would start by writing everything out so that they have a visual of what I am teaching them. I would also use a visual of a real world situation so that it relates to something they would understand. Teaching someone younger than you means they probably will not understand as easy as you understood it so, I would be very slow and make sure if they are confused to help them. I would also make sure not to be too bossy, understanding that they may not understand and that is ok.

Using the table below, complete and explain the process used for each step in solving the equation. 4c+ 12-2c = 5c - 3​
Oduvanchick [21]

Answer:

c=3

Step-by-step explanation:

4c+12-2c=5c-3  1. combine like terms

2c+12=5c-3    2. -5c on both sides

-3c+12=3      3. -12 on both sides

-3c=-9       4. /-3 on both sides

c=3

Practice Skills_ Simplifying Inequality1. 3( 1/2 - y) = 3/5 + 15y. What isthe solution to the given inequality?
Angelina_Jolie [31]

3( 1/2 - y) = 3/5 + 15y

Applying distributive property:

3*1/2 - 3y = 3/5 + 15y

3/2 - 3y = 3/5 + 15y

3/5 is adding on the right, then it will subtract on the left

3y is adding on the left, then it will subtract on the right

3/2 - 3/5 = 15y + 3y

15/10 - 6/10 = 18y

9/10 = 18y

18 is multiplying on the right, then it will divide on the left

9/10*1/18 = y

1/10*1/2 = y

1/20 = y

Two points on L1 and two points on L2 are given. Use the slope formula to determine if lines L1 and L2 are parallel, perpendicul
vlada-n [284]

Answer:

The lines L1 and L2 neither parallel nor perpendicular

Step-by-step explanation:

* Lets revise how to find a slope of a line

- If a line passes through points (x1 , y1) and (x2 , y2), then the slope

 of the line is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

- Parallel lines have same slopes

- Perpendicular lines have additive, multiplicative slopes

 ( the product of their slopes is -1)

* Lets solve the problem

∵ L1 passes through the point (1 , 10) and (-1 , 7)

- Let (1 , 10) is (x1 , y1) and (-1 , 7) is (x2 , y2)

∴ x1 = 1 , x2 = -1 and y1 = 10 , y2 = 7

∴ The slope of L1 is m1 = \frac{7-10}{-1-1}=\frac{-3}{-2}=\frac{3}{2}

∵ L2 passes through the point (0 , 3) and (1 , 5)

- Let (0 , 3) is (x1 , y1) and (1 , 5) is (x2 , y2)

∴ x1 = 0 , x2 = 1 and y1 = 3 , y2 = 5

∴ The slope of L2 is m2=\frac{5-3}{1-0}=\frac{2}{1}=2

∵ m1 = 3/2 and m2 = 2

- The two lines have different slopes and their product not equal -1

∴ The lines L1 and L2 neither parallel nor perpendicular
