Answer: 3
Step-by-step explanation:
6x-7y=4
Plug in 2 for y
6x-7(2)=4
6x-14=4
Add 14 to both sides
6x=18
Divide both sides by 6 to get x alone

Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.

Solving Multi-Step Equations Using the Distributive Property
Answer:
w=6
Step-by-step explanation:
−5(w−5)=−5
= divide both sides by -5
=w-5=1
add 5 to both sides
= w=6
Answer:
w=6
Step-by-step explanation:
5(w−5)=−5
(−5)(w)+(−5)(−5)=−5(Distribute)
−5w+25=−5
Step 2: Subtract 25 from both sides.
−5w+25−25=−5−25
−5w=−30
Step 3: Divide both sides by -5.

The value of the expression is 11.032
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
28 - 12 √(n ÷ 2)
Sustitute n = 4
= 28 - 12 √(4 ÷ 2)
= 28 - 12√2
= 28 - 12 x 1.414
= 28 - 16.968
= 11.032
Thus,
The value is 11.032

Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan
Answer:
449.10
Step-by-step explanation:
Her monthly payment, if she is considering a three-year loan is $373.47
Given the cost of the motorcycle to be $14000
If the tax rate is 6.75%, the total cost plus tax is expressed as:
Final cost = 14000+(0.0675 * 14000)
Cost of motorcycle = 14000 + 945
Cost of motorcycle = $14945
If she plans to make a down payment of $1,500 before the sales tax is applied, then;
Balance = 14945 - 1500
Balance = $13,445
If she considers a three-year loan, her monthly payment will be ;
Monthly payment = 13,445/36
Monthly payment = $373.47
Hence her monthly payment if she is considering a three-year loan is $373.47

Which describes the transformation that could have been applied to triangle ABC?
A dilation could have been applied because all of the
vertices decreased by 2 units.
O An isometric transformation could have been applied
because all of the vertices moved 2 units right and 2
units down.
A dilation could have been applied because all of the
vertices increased 2 units.
An isometric transformation could have been applied
because all of the vertices moved 2 units left and 2
units up.
Answer: I’m sorry im late, but the answer to your question should be B.
Step-by-step explanation: reason being is because the figure didnt grow/shrink like it would for a dilation so that gets rid of A. And C. And its not D. Because the dashed triangle is our original triangle not our new one so it would not make sense for it to go up and to the left. Thanks for coming to my ted talk
The image A'B'C' is formed by an isometric transformation because all of the vertices moved 2 units right and 2 units down, the correct option is B.
What is Transformation?Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.
Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.
Reflection is creating a mirror image of the object, which is same in shape and size but only the coordinates have been changed.
Translation is moving the object, up, down, left or right on the coordinate axis.
Dilation is changing the size of the object, the original object is either enlarged or compressd by certain scale factor.
The object ABC shown in the image has coordinates A ( -2, 5), B (-5, -3), C(1, -3) and,
The image has the cooridnates A'(0,3), B'(-5,-3) , C'(3, -5).
The coordinates have been transformed by translation.
The transformation is an isometric transformation could have been applied because all of the vertices moved 2 units right and 2 units down.

Find three consecutive integers such that the sum of twice the second and four times the third is twenty-five more than the first?
Answer:
3, 4, 5
Step-by-step explanation:
Three consecutive integers means that
[tex]X_1, X_2 = X_1 + 1, X_3 = X_2 + 1[/tex]
The sum of twice the second and 4 times the third is 25 times the first number
[tex]X_1 + 25 = 2X_2 + 4X_3\\X_1 + 25 = 2(X_1 + 1) + 4(X_1 + 2)\\X_1 + 25 = 2X_1 + 2 + 4X_1 + 8\\X_1 + 25= 6X_1 + 10\\5X_1 = 15\\X_1 = 3\\X_2 = 4, \\X_3 = 5[/tex]

Use the quadratic formula to find the solutions to the equation.
3x2 - 10x + 5 = 0
Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]
Hence, [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Ratio of diamonds to emeralds = 1:4.
Total = 16 emeralds
let the common ratio be x.
Emeralds = 4x and Diamonds = x
So, 4x = 16
x= 4
Thus, number of diamonds
= 4
Hence, there are 4 diamonds.
