Simplifying
2x + -1x + 7 = x + 3 + 4
Reorder the terms:
7 + 2x + -1x = x + 3 + 4
Combine like terms: 2x + -1x = 1x
7 + 1x = x + 3 + 4
Reorder the terms:
7 + 1x = 3 + 4 + x
Combine like terms: 3 + 4 = 7
7 + 1x = 7 + x
Add '-7' to each side of the equation.
7 + -7 + 1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
0 + 1x = 7 + -7 + x
1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
1x = 0 + x
1x = x
Solving
1x = x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
1x + -1x = x + -1x
Combine like terms: 1x + -1x = 0
0 = x + -1x
Combine like terms: x + -1x = 0
0 = 0
Simplifying
0 = 0

Solve using elimination
-2x+4y=-16
-2x-y=19
Answer:
x = -6 y = -7
Step-by-step explanation:
multiply the 2nd equation by -1 to get 2x + y = -19
Now -2x + 4y = -16
2x+y = -19
5y = -35
y = -7
Substitute y = -7 into the second equation to get -2x + 7 = 19
-2x = 12
x = -6
Check: Substitute values into the 1st equation
-2(-6) +4(-7) = 12 - 28 = -16
So we have the correct values for x and y

I NEED ANSWERS NOW BRAINLY!Steven has one bag that contains disks numbered 1, 2, and 3. He also has a
second bag that contains four disks lettered A, B, C, and D.
Construct a sample space of picking one disk randomly from each age and state the totals number of outcome possible
9 total outcomes
You can list out all the outcomes like this: 1a, 2a, 3a, 1b, 2b, 3b, 1c, 2c, 3c
or you can multiply 3 (the number of disks in one bag) by 3( the number of disks in the other bag)
The 2nd method is more efficient, also you can use these methods if you get another similar problem

How do you know 31/40 is greater than 3/4, but less than 4/5
Step-by-step explanation:
So you have 31/40
3/4=30/40 (multiply by 10/10)
4/5=32/40 (multiply by 8/8)
So, there you have it, 31/40 is right in between those two.
turn it into decimal format. just do the division,. 31 divided by 40 = .775 and 3 divided by 4 = .75 and 4 divided by 5 = .8. all you have to do is the division and once it is in decimal format you can tell which is greater. hope this helps

Answer:
30/40 < 31/40 < 32/40
Step-by-step explanation:
The fractions are easiest to compare when they have a common denominator. A denominator of 40 will serve.
3/4 = 30/40
4/5 = 32/40
Then the relation between the fractions is ...
30/40 < 31/40 < 32/40
3/4 < 31/40 < 4/5 . . . . 31/40 is greater than 3/4 and less than 4/5
_____
You can also compare the numbers as decimals.
3/4 = 0.750
31/40 = 0.775 . . . . greater than 3/4
4/5 = 0.800 . . . . greater than 31/40

Bryson has x+5 marbles. Stephanie has six times as many marbles as Bryson. Which expression represents how many marbles Stephanie has?
Answer:
6(X+5)
Step-by-step explanation:
Stephanie has 6 groups of x+5 which is 6 x (x+5)
= 6(x+5)
Take x+5 and multiply it by six so the answer is x+5*6. Simplified would be x+30.

Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65. How many dollars would he get at this rate for recycling 200 pounds of cans?
Answer:
$354
Step-by-step explanation:
first we need to find out how much 1 lb of can is then we can multiply that by 200 to get the answer.
so I divided 43 by 23.65 and got 1.81818181
i'll round that to $1.82 so that equals 1 lb of a can
multiply that by 200
the answer is $354
For recycling 200 pounds of cans, he will get $110.
What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65.
For 43 pounds, he recieved $23.65
For 1 pound, he will receive $(23.65/43)
For 200 pounds, she will receive $(23.65/43) x 200 or $110.
Therefore, for recycling 200 pounds of cans, he will get $110.

A cone has a base area of 20 m and a volume of 160 m. Find the height of the cone
Given:
Base area of cone =20 m²
Volume of the cone = 160 m³
To find:
The height of the cone.
Solution:
We know that, the volume of a cone is
[tex]V=\dfrac{1}{3}Bh[/tex]
Where, B is the base area and h is the height of the cone.
Putting V=160 and B=20, we get
[tex]160=\dfrac{1}{3}(20)h[/tex]
[tex]480=20h[/tex]
[tex]\dfrac{480}{20}=h[/tex]
[tex]24=h[/tex]
Therefore, the height of the cone is 24 m.

Eduardo wants to save up to take a vacation. He estimates that he’ll need about $2,000 for the vacation. He determines he can save $125 a month. To keep a track of his progress, he wants to create a graph to model the situation. How should Eduardo label and scale his graph?
A. x-axis scale, 0–20; label, Months
y-axis scale, 0–2,000; label, Total Savings ($)
B. x-axis scale, 0–20; label, Total Savings ($)
y-axis scale, 0–2,000; label, Months
C. x-axis scale, 0–2,000; label, Total Savings ($)
y-axis scale, 0–15; label, Months
D. x-axis scale, 0–15; label, Months
y-axis scale, 0–2,000; label, Total Savings ($)
Answer:
The answer should be D according to how it is arranged
Eduardo labeled and scale his graph as,
An x-axis scale, 0–15; label, Months
y-axis scale, 0–2,000; label, Total Savings ($)
Option D is correct.
Given that,
He estimated that he’ll need about $2,000 for the vacation.
He determines he can save $125 a month.
To keep a track of his progress, he wants to create a graph to model the situation. How should Eduardo label and scale his graph is to be determined
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
If he is saving $125 a month and has an initial saving of $125.
Total number of months = 2000 - 125 / 125
= 1875 / 125
= 15
So,
x-axis and y-axis can be labeled as total months and total saving respectively.
Thus,
An x-axis scale, 0–15; label, Months
y-axis scale, 0–2,000; label, Total Savings ($)
Option D is correct.
