2x^2 + 24x + 72 - 50

2x^2 + 24x + 22

hope this helps <3

Answer:

See below.

Step-by-step explanation:

The 3 marked angles add up to 360 degrees.

5x + 12 + 10x - 37 + 9x + 1 = 360

24x - 24 = 360

24x = 384

x = 384/24 =  16

The large angle at C = 10(16) - 37

= 160 - 37 = 123 degrees.

So m <BCA = 180 - 123

=  57  degrees    (adjacent angles add up to 180).

Answer:

21

Step-by-step explanation:

Well you basically divide 3 and 1/2 by 1/6 which you would you have to simplify the 3 and 1/2 which is 7/2 and switch the denominator and numerator of the 1/6 which would be 6/1 and after you multiply(7/2 x 6/1=42/2) it would be 42/2 which you would have to simplify by dividing 42 and 2 which is 21. There you go I hope this helps.

Answer:

21.

Step-by-step explanation:

That would be  3 1/2 divided by 1/6.

= 7/2 / 1/6

= 7/2 * 6

= 42/2

= 21 glasses.

Answer:

number is 1

Step-by-step explanation:

let the number be n , then 2 times the number is 2n and 3 more than this is

2n + 3 , so

2n + 3 = n + 4 ( subtract n from both sides )

n + 3 = 4 ( subtract 3 from both sides )

n = 1

That is the number is 1

The required number is 1 which represents "3 more than 2 times a number is equal to that number plus 4"

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

Let the required number would be x.

According to the given question, translate the phrase into an algebraic equation:

3 + 2x = x + 4

Subtracting x from both sides gives:

3 + 2x - x = x + 4 - x

Simplifying the left side gives:

3 + x = 4

Subtracting 3 from both sides gives:

3 + x - 3 = 4 - 3

Simplifying the left side gives:

x = 1

Therefore, the required number would be 1.

Step-by-step explanation:

a = 7 cm

b = 10.4 cm

h = 6.7 cm

Area of trapezium = ?

we have the formula

Area of trapezium

= 1/2 * h ( a + b)

= 1 / 2 * 6.7 ( 7 + 10.4)

= 1/2 * 6.7 * 17.4

Answer:

I mean c and d but you wrote this weirdly

Step-by-step explanation:

It is a cyclic quadrilateral.

The sum of interior angles of this polygon is equal to 180 degrees.

ATQ,

2x+26y=180

x+13y=90 ....(1)

3x+21y=180

x+7y=60 ....(2)

Subtract equation (1) from (2).

x+7y-(x+13y) = 60-90

x+7y-x-13y=-30

-6y=-30

y = 5

Put the value of y in equation (1

x+13(5) = 90

x+65=90

x = 90-65

x = 25

So,

∠DAB = 26y = 26(5) = 130°

∠ABC = 3x = 3(25) = 75°

∠BCD = 2x = 2(25) = 50°

∠ADC = 21y = 21(5) = 105°

    x = 25, y = 5

    m∠DAB = 26(y) = 180°

    m∠ABC = 3x = 75°

    m∠BCD = 2x = 50°

    m∠ADC = 21y = 105°

From the picture attached,

By using the property of cyclic quadrilateral,

m∠A + m∠C = 180°

26y + 2x = 180

13y + x = 90 --------(1)

m∠B + m∠D = 180°

3x + 21y = 180

x + 7y = 60 --------(2)

Subtract equation (2) from (1),

(13y + x) - (x + 7y) = 90 - 60

6y = 30

y = 5

Substitute y = 5 in equation (1),

13(5) + x = 90

x = 90 - 65

x = 25

Substitute the values of 'x' and 'y' to get the measures of the angles,

m∠DAB = 26(y) = 180°

m∠ABC = 3x = 75°

m∠BCD = 2x = 50°

m∠ADC = 21y = 105°

         Therefore, values of the variables will be,

                            x = 25, y = 5

                            m∠DAB = 26(y) = 180°

                            m∠ABC = 3x = 75°

                            m∠BCD = 2x = 50°

                            m∠ADC = 21y = 105°

Answer:

A, $151.36

Step-by-step explanation:

Step #1: Change 5.3% to a decimal.

To do that just move the decimal point 2 places to the left (same thing as dividing by 100). Also remember that every number has invisible zeros in front of it that don't change the number at all.

So basically to change 5.3% to a decimal just move the decimal point in front of 5 (that's one time), then in front of the invisible zero (that's 2 times) so you have .053

Step #2: Then multiply .053 times $143.74

The answer should be $7.61822 if you did it right.

Step #3: Add #143.74 and $7.61822 to find the total with the sales tax.

The answer should be $151.35822.

But we don't do that in money so round the total to the nearest cent. Look at the third decimal space to see if you're rounding up or down. If the decimal space is 0-4, then round down (so in this case if the 8 was a 2, you would keep the 5 like it is and the answer would be $151.35). But if the third decimal space is 5-9, then round up.

In this case since the third decimal space is a 8, we are rounding up and changing the 5 to a 6.

So your final answer should be $151.36.
