4 (10-x) = 8x + 4
What is x?
Answer:
3 = x
Step-by-step explanation:
4 (10-x) = 8x + 4
Distribute
40 -4x = 8x+4
Add 4x to each side
40 -4x+4x = 8x+4 +4x
40 = 12x+4
Subtract 4
40 -4 = 12x+4-4
36 = 12x
Divide each side by 12
36/12 = 12x/12
3 = x
At the toy store, 3 toy cars cost $2.37. How much does it cost to buy 30 toy cars?
Answer:
23.7
Step-by-step explanation:
Multiply 2.37 by 10
Answer:
$23.70
Step-by-step explanation:
3 toy cars
Each cost $2.37
How much does 30 toy cars cost
________________________________
We know that 3 toy cars cost 2 dollars and 37 cents. To solve, we first need to find what times 3 gets us 30.
3 * ? = 30
30 / 3
10
Therefore you need to multiply the amount of toy cars by 10 to get thirty toy cars, since three of them cost 2.37, multiply 10 by 2.37.
$2.37 * 10
$23.70
What is the value of x in the solution to this system of equations?
3x - 5y = 22
y = -5x + 32
Answer:
Replace all occurrences of y with −5x+32 in each equation.
28x−160=22
y=−5x+32
Solve for x in the first equation.
x=13/2
y=−5x+32
Replace all occurrences of x with 13/2 in each equation.
y=−1/2
x=13/2
The solution to the system is the complete set of ordered pairs that are valid solutions. ( 13/2, −1/2 )
The result can be shown in multiple forms. Point Form: (13/2,−1/2)
Equation Form:
x=13/2, y=−1/2
Step-by-step explanation:
The value of x in the solution to given system of equations is 13/2
Here,
Given system of equations are;
3x - 5y = 22 -----(i)
y = -5x + 32 -----(ii)
What is system of equations?
A system of equations is a set of two or more equations with the same variables.
Now, in given system of equations put the value from (ii) in (i), we get
⇒ 3x - 5 (-5x + 32) = 22
⇒3x + 25x - 160 = 22
⇒28 x = 182
⇒ x = 182/28
⇒ x = 13/2
Hence, The value of x in the solution to given system of equations is 13/2.

Landon made 36 muffins she put the same number of muffins on each of four plates how many my friends did she put on each plate
Answer:
the muffins put on each plate is 9
Step-by-step explanation:
The computation of the muffins put on each plate is shown below:
= Total muffins ÷ Total number of plates
= 36 ÷ 4
= 9 muffins on each plate
hence, the muffins put on each plate is 9
If △ABC∼△LMN and △LMN∼△XYZ, is △ABC∼△XYZ? Use the AA similarity criterion to support your answer.
Answer:
yes because transitive property
Step-by-step explanation:
if abc~lmn, then the angles a and b are similar to angles l and m. and if lmn~xyz then angles l and m are similar to angles x and y. therefore, using transitive property, angles a and b would be similar to angles x and y. so using AA similarity, the two triangles would be similar

Answer:
y = 3x - 12
Step-by-step explanation:
y = mx + b
(m is the slope)
y = 3x + b
plug in your point
9 = 3 (7) + b
9 = 21 + b
subtract 21 on both sides
b = -12
y = 3x - 12

find the value of x and please show how
Answer:
?=91 degrees.
Step-by-step explanation:
There is no x- I'll find ? though.
So, angles in a triangle must equal 180.
180-29-62=89. The last angle in the triangle is 89 degrees.
A straight angle is equal to 180 degrees. ? + 89=180.
180-89=91.
?=91 degrees.

Plz mark brainliest
Step-by-step explanation:
I'm assuming you mean Point- Slope Form of a linear equation.
If so, then a point slope form of a linear equation is one that looks something like this:
y - y₁ = m (x - x₁)

n is the middle integer of three consecutive positive integers.
The three integers are multiplied to give a product.
n is then added to the product.
Prove that the result is a cube number.
n must be used in your proof.
Your final line must consist of only,
= n^3
Answer :
[tex]\boxed{\textsf{ The final answer is \textbf{n}$^{\textbf{3}}$ .}}[/tex]
Step-by-step explanation:
Its given that n is the middle out of the three consecutive integers . So ,
The last integer will be :-
[tex]\sf\implies Last \ Integer \ = \ n - 1 [/tex]
The next Integer will be :-
[tex]\sf\implies Next \ Integer \ = \ n + 1 [/tex]
Now the Question says that the three integers are multipled to give a product . So that would be.
[tex]\sf\implies Product_{(three\ consecutive\ integers)}= (n-1)n(n+1) = (n^2-1)(n) = \pink{n^3-n}[/tex]
Now thirdly it's given that n is added to the given integer . That would be ,
[tex]\sf\implies Adding\ n = \ n^3 - n + n = \pink{n^3} [/tex]
Here - n and +n gets cancelled. So we are ultimately left out with n³.
Hence the final number is a cube of some number.
