Answer:

i would think 32

Step-by-step explanation:

cause you said one fourth and i multiplied 8 and 4 and got 32

Answer:

3x(2x - 5)

Step-by-step explanation:

because you have x² that means that you have to timse x by x to get x².

6 divided by 15 gets you a decimal but both number goes into the 3 times table

Therefor 6x² - 15x = 3x(2x-5)

If you need to check just times 2x by 3x which would get you 6x² and 5 by 3x which would get you 15x

Answer:

3x(2x-5)

Answer:

18

Step-by-step explanation:    

To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.

Now, break it by parts - "three times a number" would be [tex]3n[/tex]. The "is" means that it equals something, giving us [tex]3n =[/tex]. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: [tex]5n -36[/tex]. So, put it all together and it is [tex]3n = 5n-36[/tex].

Next, solve the equation for n. The answer will be the number.

[tex]3n = 5n-36\\0 = 2n - 36\\36 = 2n \\n = 18[/tex]

Thus, the number is 18.

Answer:

She can make three shirts and will have 7/56 left.

Step-by-step explanation:

49/56-14/56=35/56 (one shirt) 35/56-14/56=21/56 (two shirts) 21/56-14/56=7/56 (three shirts)

Answer:

2/5 x ? = 4/3?

4/3 / 2/5= ?

Quick method is quick change flip, Change the division sign into multiplication and switch the values in the denominator and numerator of the second fractiom

4/3 x 5/2 = 20/6

simplify to 10/3

x or ? = 10/3

written as a mixed number is is 3 1/3

Step-by-step explanation:

Answer:

x² – x – 12 = (x – 4)(x + 3)

Step-by-step explanation:

Identify two numbers that add to -1 and multiply to -12, let's call them p and q.

So ax² + bx + c = (x + p)(x + q)

pq = c

p + q = b.

It is easier to find these numbers by finding factors of -12.

This can be done by splitting the number up until all the numbers are prime.

-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)

There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.

We can eliminate them by adding them up.

6 + -2 = 4 ≠ -1 so that can't be it.

-6 + 2 = -4 ≠ -1 so that can't be it either.

-3 + 4 = 1 ≠ -1

therefore p and q are 3 and -4 because 3 + -4 = -1.

so x² – x – 12 = (x – 4)(x + 3)

p = -4, and q = 3.

(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

Answer:

d

Step-by-step explanation:

Answer:

the answer is D

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given

6x + 2 - 8x + 7 = 4x + 1 ← simplify left side

9 - 2x = 4x + 1 ( subtract 4x from both sides )

9 - 6x = 1 ( subtract 9 from both sides )

- 6x = - 8 ( divide both sides by - 6 )

x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

Answer: C. Zero

Step-by-step explanation:

The Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line shown in the image is horizontal, i.e. all of its points have the same y-coordinate regardless of their x-coordinate.

Take two random points on the line like (0,-2) and (2,-2), the slope is:

[tex]\displaystyle m=\frac{-2+2}{2-0}=0[/tex]

The slope is zero

Answer: C. Zero

Answer:

Lol, do you still need the answer? If you do, here it is:

The equation is : X+Y=21,   X+Y+21 can be the following options:

1+20=21

2+19=21

3+18=21

4+17=21

5+16=21

6+15=21

7+14=21

8+13=21

9+12=21

10+11=21

Answer:

2

Step-by-step explanation:

4.05+14.40=4.50p+13.50

4.05p-4.5p=13.5-14.4

-0.45p=-0.9

p=2

Answer:

q = 0

Step-by-step explanation:

8q + 12 = 4( 3 + 3q )

Distributive property

8q + 12 = 4 ( 3 + 3q )

8q + 12 = 12 + 12q

Inverse operations

8q + 12 = 12 + 12q

-8q               -8q

12 = 12 + 4q

-12  -12

0 = q

q = 0

Answer:

Q = 0

Step-by-step explanation:

1. Expand.

8q + 12 = 12 + 12q

2.cancle 12 on both sides.

8q = 12q

3. Move all terms to one side.

8q - 12q = 0

4. simplify 8q - 12q to -4q.

-4q = 0

5. Divide both sides by -4.

q=0

therefor, the answer is q=0
