just plugged in 4 for x

y=1.5(4)+3

hope this helps and is right haha <3

Answer:

x = 4

Step-by-step explanation:

Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.

Taking [tex]-24x=6x^2[/tex], we can simplify this just to make it a bit more professional, to say [tex]6x^2=-24x[/tex] (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).

Now, we can really start by dividing both sides by 6, to get [tex]x^{2} =-4x[/tex], and then divide both sides by x to get [tex]x=4[/tex].

So, the answer of this quadratic equation is x = 4.

Answer:

Its the snack shop because for each bar it is 1.25 each.

Step-by-step explanation:

Answer:

The answer is Snack Shop.

Step-by-step explanation:

The equation given us, y=1.25x means this store sells a bar of granola for $1.25.

However the other store sells there granola bar for $1.30.

1.25 is less than 1.30.

Choose the store that sells their granola bar for $1.25.

B. They are alternate interior angles, so angle 3 also measures 130°.

Explanation: This is the correct answer on Edge 2021, just took the unit test. Hope this helps ^-^.

They are alternate interior angles, so angle 3 also measures 130°. The correct option is B.

The angle formed by the line intersecting two parallel lines is called the alternate interior angle. These two angles are equal in magnitude.

Here, according to the given figure, lines a and c are parallel lines and pipe cleaner is a transversal that is passing through these parallel lines.

Therefore, by the property of parallel lines, the corresponding and alternative exterior or interior angles made by the common transversal ( pipe cleaner) on lines a and c must be equal, and here ∠3 and 130° are alternative interior angles by lines a and c with the same transversal, So, they must be equal.

The complete question is given below:-

A pipe cleaner lay across a wire shelf. The wires that make up the shelf are parallel, and the pipe cleaner is a transversal. The parallel wires are labeled a, b, and, c, and the angles are labeled with numbers. The measure of one angle is 130°. Which statement is true regarding the 130° angle and angle 3?

A. They are same-side interior angles, so angle 3 measures 50°.

B. They are alternate interior angles, so angle 3 also measures 130°.

C. They are corresponding angles, so angle 3 also measures 130°.

D. They are alternate exterior angles, so angle 3 measures 50°.

Answer:

Step-by-step explanation:

Given parameters:

Mark up percentage  = 150%

Original cost = $488

Sales tax = 5%

Unknown:

His total cost  = ?

Solution:

Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.

 Since the emerald was marked up by 150%;

   New cost  = (1 + 1.5) x $488 = $1220

Now, the additional tax was 5%;

   Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61

So, the total cost = New cost + tax  = $1220 + $61 = $1281

Step-by-step explanation:

9 = - 7w + 12w - 6

by transposing,

9 + 6 = -7w + 12w

15 = 5w

w = 15 / 5

w = 3

Hope this helps

plz mark as brainliest!!!!!!

Answer:

[tex]w=3[/tex]

Step-by-step explanation:

[tex]9 = -7w + 12w -6[/tex]

Start by combining like terms ([tex]-7w+12w[/tex]):

[tex]9=5w-6[/tex]

Add [tex]6[/tex] to both sides of the equation:

[tex]15=5w[/tex]

Divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]5[/tex]:

[tex]3=w[/tex]

_

Check your work by substituting the solved value of [tex]w[/tex] ([tex]3[/tex]), into the initial equation:

[tex]9 = -7(3) + 12(3) -6[/tex]

Multiply:

[tex]9=-21+36-6[/tex]

Combine like terms:

[tex]9=9[/tex]

Since both sides of the equation are equal, our answer is correct!

Answer:

Y=5-2X

Step-by-step explanation:

Answer:

IF YOU HAVE TO SOLVE FOR Y THEN TAKE X AS ANY NUMBER YOU WANT.

SUPPOSE X=2

PUT THE VALUE IN THE EQUATION THEN U WILL GET-

Y+2(2)=5

= Y+4=5

= Y=5-4

= Y=1

THIS IS JUST ONE EXAMPLE BUT THERE CAN BE INFINITIVE NUMBER OF ANSWERS FOR THIS QUESTION.

I WILL SHOW U ONE MORE EXAMPLE.

IF X=1

THEN THE EQUATION WILL BE-

Y+2(1)=5

Y+2=5

Y=5-2

Y=3

SO HERE WE GOT Y=1&3

AND ALSO Y CAN HAVE INFINITE SOLUTIONS (THIS IS ON THE BASIS OF THE PROPERTY OF LINEAR EQUATION, I.E., A LINEAR EQUATION CAN HAVE INFINITIVE SOLUTIONS)

number one 720 second 36

Step-by-step explanation:

Answer:

the first one is is 720$ second one is 36$

Step-by-step explanation:

You divide 166 by 2. The answer would be 83.

The value of splitting 166 in half gives two equal halves of 83 each.

When 'split' a number in half, dividing the number into two equal parts.

Here want to split the number 166 in half.

Perform a division operation by dividing 166 by 2.

Division is the opposite operation of multiplication.

When divide a number by 2, you are essentially finding the value of half of that number.

So, the calculation is as follows:

166 ÷ 2 = 83

This means that half of 166 is 83.

Divide the number 166 into two equal parts, each being 83.

If add both halves together, you get the original number back:

83 + 83 = 166

Therefore, dividing 166 by 2 allows to splitting it equally into two halves, each having a value of 83.

given that she earns $13.05 per hour

and also given that she works for 190 hours in a month

then in a month, her earnings will be

=$13.05*190

=$2479.5

alternatively,

per week she works 47.5hours

in a week she will earn 13.05*47.7= $622.485

Step-by-step explanation:

2/3 (x-4)=2x

or, 2x-8/3 =2x (multiply(x-4) by 2/3)

or, 2x-8 =3×2x

or, 2x-8 =6x

or, 2x-6x = 8

or, -4x = 8

or, x= 8/(-4)

or, x= -2
