What’s 20 times 6 plus negative 2?

Answer:

a=-8 b=2

Step-by-step explanation:

x^2+6x-16

x^2+(8-2)x-16=0

x^2+8x-2x-16=0

X(X+8)-2(X+8)=0

(X+8)(x-2)=0

Compare with (X+a)(X+b)

Where we get a=-8 b=2

Answer:

[tex]\huge\boxed{216 \ \text{in}^2}[/tex]

Step-by-step explanation:

We can find the surface area of an object by finding the area of all its sides and adding them up.

We know that a cube has 6 identical sides. Therefore, we can just find one side and multiply by 6.

A cube is made up of 6 squares. We can find the area of this square by squaring the length (multiplying it by itself).

Since the length is 6, that means the area of one side of the cube must be [tex]6^2 = 6 \cdot 6 = 36 \ \text{in}^2[/tex]

Since there are 6 identical sides, the total surface area must be:

[tex]36 \cdot 6 = 216 \ \text{in}^2[/tex]

The system reveals that there are 15 questions worth 2 points and 10 questions worth 3 points on the test.

Given:

Total question = 25

Marks for question= 2 or 3 points

Total marks = 60

Let x be the 2-point questions and y be the number of 3-point questions.

As, there are a total of 25 questions then

Equation1 : x+ y= 25

and, total points in the test is 60 then

Equation 2 : 2x+ 3y = 60

From equation 1: y= 25 -x.

Substitute y = 25 -x  into the Equation 2

2x + 3(25-x) = 60

2x + 75- 3x= 60

75 - x = 60

-x = 60 - 75

-x = -15

x= 15

Now, the value of y is

y = 25 -x

y = 25 - 15

y =  10

Answer:

x = ⅗ = 0.6

Step-by-step explanation:

A square has four equal sides.

If a square has a side length of [tex] x + 3 [/tex], therefore,

Perimeter of the square = [tex] 4(x + 3) [/tex]

[tex] = 4x + 12 [/tex].

Also, a regular octagon has 8 equal sides.

If it has a side length of 3x, therefore:

Perimeter of the octagon = [tex] 8(3x) [/tex]

= [tex] 24x [/tex]

Given that the Perimeter of the rectangle and the octagon are the same, to find the value of x, set each perimeter equal to the other.

Thus:

[tex] 24x = 4x + 12 [/tex]

Subtract 4x from each side

[tex] 24x - 4x = 12 [/tex]

[tex] 20x = 12 [/tex]

Divide both sides by 20

x = 12/20 = ⅗ = 0.6.

Answer:

c. Susan's debt-to-income ratio decreased by about 15%

Step-by-step explanation:

Susan's previous salary = $52,000

Susan's new salary = $68,000

Susan's mortgage = $1,500

The total of three minimum credit card payment = $350

Her lease payment = $280

Her student loan payment = $250

Her personal loan payment = $325

Therefore, her total debt = $1,500 + $350 + $280 + $250 + $325 = $2,705

Her new Debt to loan ratio = (Her total deb)/(Her total new income) = 2705/68000 = 3.9779 %

Her previous to loan ratio = (Her total deb)/(Her total previous income) = 2705/52000 = 5.2%

The percentage change in her debt to income ratio = (5.202 - 3.9779)/5.202 ≈ 23% decrease

Therefore, the best option is Susan's debt-to-income ratio decreased by about 15%.

Answer:

$42.12

Step-by-step explanation:

Calculation for How much will Gretta pay in total for this transaction

First step is to calculate the new price

New price=$65- ($65*40%)

New price=$65-26

New price=$39

Second step is to calculate the sales tax amount

Sales tax=8%*39

Sales tax=$3.12

Last step is to calculate How much will Gretta pay in total for this transaction using this formula

Total Amount to be paid=New price+Sales tax

Let plug in the formula

Total Amount to be paid=$39+$3.12

Total Amount to be paid=$42.12

Therefore the amount that Gretta will pay in total for this transaction will be $42.12

$105.  I don't know about how much the skateboard is but on an average skateboard yes it is enough.

Step-by-step explanation:

If you get $3 a week and you have lived 20 more weeks. You would multiply 3 by 20 and get $60. Then you would add $60 to $45 and get $105. The average skateboard costs $70. So yes, a skateboard could be bought for $105. Hope this helps! Have a great day!

$105.

45 + 3w gives the amount of money you save after w weeks. We need to find amount of money we have after 20 weeks.

In equation we have to arrange all variables on one side and constants on other side

To save for a skateboard, If you get $3 a week from your aunt and you have lived 20 more weeks.

We need to multiply 3 with 20 to get the amount for 20 weeks.

So 3*20=$60 for 20 weeks...(*)

and from given

The expression 45 + 3w gives the amount of money you save after w weeks.

$45+3W

=$45+$60 (From *)

=$105

Therefore $10 money is enough to buy the skateboard.

Answer:1.875

Step-by-step explanation:

The solution to the expression "-2.5 times (-3/4)" is 1.875.

A set of numbers, variables, and mathematical operations that may be evaluated to yield a value are referred to as expressions in mathematics. A single number or variable might be used, or it can be more complicated and involve several words and processes.

To find the solution to the expression "-2.5 times (-3/4)", we can follow these steps:

Step 1: Multiply -2.5 by -3/4,

-2.5 x (-3/4) = (2.5/1) x (3/4) = (2.5 x 3) / (1 x 4) = 7.5/4

Step 2: Simplify the fraction,

To simplify the fraction 7.5/4, we divide the numerator (7.5) by the denominator (4).

7.5 ÷ 4 = 1.875

In summary, when we multiply -2.5 by -3/4, we get 7.5/4, which simplifies to 1.875.
