b. Has equal coefficients for x^3 and for x
anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:
Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???
Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13
Hope this helped, I tried to explain it easily.
1. the pizza at kwame's party is cut to into eighths, kwame eats 3 slices and the rest of the family eats 18 slices. there's 3 slices left over, how many pizza's have been ordered? and how do you know?
2. hair scrunchies come in a packages of 5.
suppose you have 2 1/5 of these packages to share among 4 friends.
a) do you have enough scrunchies to give each friend 3 scrunchies? how do you know?
b) do you have enough scrunchies to give each friend 2? how do you know?
(you don't have to answer the 2 questions if they are too hard for you)
Answer:
1. answer is 3 pizzas
2. a) yes b) yes
Step-by-step explanation:
1. If kwame eats 3 slices and the family eats 18 slices thats a total of 21 slices. Each pizza is cut into eighths so there has to be 8 slices to each pizza. There are 3 slices left over for a total of 24 when the eaten slices are added to the left over slices. 24 divided by 8 is 3 pizzas.

Answer:
n = 10 and n = 16
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then
[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]
= [tex]4^{10}[/tex] , thus n = 10
---------------------------------------------
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then
[tex](3^2)^{8}[/tex]
= [tex]3^{2(8)}[/tex]
= [tex]3^{16}[/tex] , thus n = 16
On a coordinate plane, a line goes through (0, 4) and (4, 16). The line representing the first table is shown in the graph. What is the solution to the system of linear equations represented by both tables? 2 tables. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, 0, 2, 4. Column 2 is labeled y with entries negative 2, 4, 10, 16. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, 0, 2, 4. Column 2 is labeled y with entries 18, 16, 14, 12.
Answer:
x=3
y=13
Step-by-step explanation:
okay so what that means is that the two equations are y=-x+16 and y=3x+4
so y+x=16
y-3x=4
so 4x=12 so x=3
y=13 is the solution

Richard mowed 30% of his lawn in 18 minutes. How many minutes will it take him to mow the rest of his lawn at this rate? PLs answer quick!
Answer:
It should take about 54 minutes!
Step-by-step explanation:
30% / 18 = 100% / ?
30 x ? = 100
30 x 3(roughly) = 100
So, 18 x 3 = 54.
It should take about 54 minutes!
A _____________ ratio in any proportional relationship.
Answer:
a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x
If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

Answer:
8 because if you take a row away from the total, you have 8, and that's how many are hidden
Step-by-step explanation:
Answer: there are eight blocks hidden in the cup.
Step-by-step explanation:
seeing that we don’t know how many blox are in the cup The cup would be a variable in this situation.
x + 4 = 12 cubes
to find your answer you would’ve solve for X, a.k.a. the cup.
x + 4 = 12 cubes
first you would do the inverse operation of addition so instead of adding four you subtract four from four, so that it cancels out. Whatever you do to one side you have to do to the other side so you would have to subtract 4 from The previous 12 cubes.
X = 12 - 4
and your final answer would be 8 cubes
x = 8
there are eight blocks/cubes hidden in the cup
If you don’t know don’t answer-

Answer:
120πcm²
Step-by-step explanation:
Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.
First we need to figure out the area of the top circle and bottom circle.
We know that the formula for the area of a circle is:
πr²
So we need both circles, our formula becomes:
2πr²
Let's substite our radius in.
2 × π × 4² = 32πcm²
Now we need to find the area of the sides itself. Our formula here is:
2 × π × r × h
Let's substitute our radius and height in:
2 × π × 4 × 11 = 88πcm²
Let's now add both of these together:
88πcm² + 32πcm² = 120cm²
Remember to add your measurements!
Hope this helped!

-3z - (3z - 2) = 4(z + 3)
Can someone please tell me what to do step by step Pleaseee
Answer:
z = -1Explanation:
-3z - (3z - 2) = 4(z + 3)
Expand -3z - (3z - 2): -6z + 2
Expand 4(z + 3): 4z + 12
-6z + 2 = 4z + 12
Subtract 2 from both sides
-6z + 2 - 2 = 4z + 12 - 2
Simplify
-6z = 4z + 10
Subtract 4z from both sides
-6z - 4z = 4z + 10 - 4z
Simplify
-10z = 10
Divide both sides by -10
-10z / -10 = 10 / -10
Simplify
z = -1- zyxx

The Science Club went on a two-day field trip. The first day the members paid $30 for transportation plus $10 per ticket to the planetarium. The second day they paid $100 for transportation plus $7 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.
An expression that represents the total cost in dollars for two days for the n members of the club is given by
Answer:
just add all the numbers which means $147
Answer: I believe is $147 because u have to add all the number and it will give u the total of 147. So the total cost in dollars for two days for the n members of the cub will be $147.
