PLEASE HELP ME WITH MATH (also please tell me how you got the answer so I understand)

Answer:
1st=3x+9, 2nd=8x, 3rd=4x+3y, 4th=neither, 5th=neither, 6th=4x+3y, 7th=3x+9, 8th=8x.
Step-by-step explanation:
for the 1st one cancel out the y's, 3x+9. for the 2nd one: 2x-1x+7x, (2-1+7)x, 8x. for the 3rd one: 2x+2y+2x+y, 4x+2y+y, 4x+3y. for the 4th one: 7x+x+0-y, 8x-y. for the 5th one: 2x+2y+2x, 4x+2y. for the 6th one: 4x+4y-y, 4x+3y. for the 7th one: 2x+6+x+3, 3x+6+3, 3x+9. for the 8th one: 5(2x)-2x, 5 * 2x-2x, 10x-2x, 8x.
Answer:
The answers would be :
first table (equivalent to 8x ) = 2x-x+7x , 7x+x+0×y , 5(2x)-2x
second one (equivalent to 4x+3y) = 2x+2y+2x+y , 4x+4y-y
third one = every expression left but 2x+2y+2x .
you have to calculate them ! for example look at the first one ----> y+3x-y+9 is equivalent to 3x+9 'cause y-y = 0 ,so 3x +9 will be the left expression and you can't calculate it because the both left items in expression are not from the same type , one of them has a x but the other one doesn't have .
or for example the second one is 2x-x+7x and you know that -x can be written as -1x ,so it becomes like 2x+-1x+7x = 8x .
in the above example we could calculate numbers 'cause all of them have the same variable .
hope it was kinda helpful , sorry for bad english :D
ask me if you have further questions .

What do I do in this problem?
Answers
Answer: p=60
Step-by-step explanation:
Angles on a straight line always add up to 180 degrees.
So, because you have an angle on the straight line with the arrow going up, you have to do:
180-110=70
This will give you the angle inside of the triangle that is next to 110.
Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:
180-130=50
This gives you the angle inside the triangle next to 130.
Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:
70+50=120
Then you would take the answer away from 180 like this:
180-120=60
So, p=60
Hope this helps :)
Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.
Answers
Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478

The sales tax is 8%.
What is the total cost for the game including sales tax?
Answers
Answer:
$64.8
Step-by-step explanation:
To determine the tax, you want to make the percent into a decimal by moving the decimal point over two times the the left, which means 8% would be 0.08. Then, multiply the new decimal by the price. 60 times 0.08 is 4.8. Now, add the tax to the original price. 60+4.8=64.8, so therefore the total cost is $64.8

There is a line that includes the point (4,8) and has a slope of 4 What is its equation in slope- intercept form
Answers
Answer:
y=4x-8
Step-by-step explanation:
1) The slope-intercept form of an equation looks like this:
y=mx+b
The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.
2)We have the slope you entered in, so we'll plug that in first:
y=4x+b
3) Now, let's plug in that point you entered in to solve for b:
y=4x+b
8=4(4)+b
8=16+b
8-(16)=b
-8=b
4) Now that we have both our slope, m, and our y-intercept, b, values, we can plug them in to get our equation:
y=mx+b
y=4x-8

What is the rate of change for the function represented
in the table?
$0.50 per book
$0.67 per book
$1.07 per book
$1.50 per book
Answers
The rate of change for the function represented in the table is 1.5.
What is Rate of change?Rate of change, also known as slope or gradient, is a measure of how quickly one variable is changing with respect to another variable. In mathematics, it is typically represented as the ratio of the change in the output variable (y) to the change in the input variable (x) over a given interval.
Let's choose the points (100, 50) and (250, 275). The change in profit between these two points is:
Δy = 275 - 50 = 225
The change in books sold between these two points is:
Δx = 250 - 100 = 150
The slope of the line between these two points is the ratio of the change in profit to the change in books sold:
m = Δy/Δx = 225/150 = 1.5
So the rate of change for the function represented in the table is 1.5,
which means that for every additional book sold, the profit increases by $1.50.
