plz solve 20 points plz solve plz solve

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5

Answer: B

Step-by-step explanation:

y intercept is -2

y = 3/2x^2 + 4x – 2

y = 3/2(0^2) + 4(0) – 2 = -2

and x intercepts are

0 = 3/2x^2 + 4x – 2

about

x =  0.43050087, -3.09716754

Answer: 40 ft^3

Step-by-step explanation:

l*w*h to find volume of space in the drawer so

5*4=20 and 20*2= 40 so the volume is 40

Answer:

The area is 40 square feet.

Step-by-step explanation:

To find area, you multiply length x height x width. 5x4x2=40

Answer:

[tex]\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Step-by-step explanation:

The formula for finding the any side of the triangle is

[tex]a^{2}+b^{2} =c^{2}[/tex]

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

[tex]2^{2}+b^{2} =11^{2}[/tex]

[tex]4+b^{2} =121[/tex]

To find side b, we have to make it alone on one side. Subtract 4 on both side.

[tex]b^{2} =117[/tex]

Now square root both sides, and that leaves us with:

[tex]b=\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Answer:

A) But

B) Conversely

C) On the other hand

Step-by-step explanation:

Answer:

12.25 cm^2

Step-by-step explanation:

Draw a segment from the bottom of the 1.5-cm vertical side to the bottom side of the entire polygon.

Now you have two rectangles.

The left rectangle has dimensions 3.5 cm by 1.5 cm.

The right rectangle has length 5 cm - 1.5 cm = 3.5 cm and width 3.5 cm - 1.5 cm = 2 cm.

The total area is the sum of the areas of the two rectangles.

area of rectangle = length * width

total area = 3.5 cm * 1.5 cm + 3.5 cm * 2 cm

total area = 5.25 cm^2 + 7 cm^2

total area = 12.25 cm^2

Answer:

19!

Step-by-step explanation:

Probability of getting "2" in 1 roll = 1/6

No: of times played = 114

Times expect to roll a "2" in 114 times = 1/6 x 114  = 19

I hope im right!!

Answer:

-7i - 9

-11i + 12

Step-by-step explanation:

i stands for imaginary number, in which i² = -1

6i² = 6 * -1 = -6

-6 - 7i - 3

Combine like terms:

-6 - 3 = -9

-7i - 9

2i^2 = 2 * -1 = -2

Combine like terms:

-11i + 14 - 2

-11i + 12

Answer:

321900

Step-by-step explanation:

3.5 x 10^5 - 2.81 x 10^4

To solve this, you need to use the Order of Operations to do the exponents first.

3.5 x 100000 - 2.81 x 10000

350000 - 28100

= 321900

your answer is C I'm definitely sure

Answer:

The answer is D.

First you need to  distribute the power on the first bracket, then to make it easier you rearrange the equation into fraction

so it will look like that : [tex]\frac{3^{5}.2^{5} }{3^{2}.2^{3} }[/tex]

and there is a rule that says:

To divide exponents (or powers) with the same base, subtract the exponents.

[tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]

[tex]=3^{5-2}.2^{5-3} \\= 3^{3}.2^{2}[/tex]

Step-by-step explanation:

x+y=3

y=2x

x+2x=3

x=3-2x

it's your required answer

Answer:

x = -3

If you need to find the value of y than substitute x=-3 into equation (1) .

Answer:

v = 60

Step-by-step explanation:

65 + 55 + v = 180

65 + 55 = 120

180 - 120 = 60

v = 60

Answer:

Step-by-step explanation:

9/2 is the slope. Slope defines how steep is the straight line.

Slope =  change in y ÷ change in x

In this model, 9 refers to the vertical distance between two points

and 2 refers to  the horizontal distance between two points.

9/2 is a positive slope. It indicates that if 'x' increases, y also increase.

gustavo is wrong

Step-by-step explanation:

48 calculated on my calculator and i worked it out irl your welcome

Answer:

19.65 left

Step-by-step explanation:

The total amount that he has is 3 * 12 =                   36 dollars.

From this he buys a CD for                          15.00

There is a 9% tax on 15 dollars 15*9/100 =   1.35

Amount spent =                                                         16.35

Amount left                                                               19.65

Paul saves $3 each week for 12 weeks.

3 × 12 = $36

He buys the CD for $15

The tax is 9% out of $15.

15 × 9/100 = $1.35

In total he spent $16.35

To find the money he has left we take the total amount of money he had before he bought anything and subtract it with the money he spent.

36 - 16.35 = $19.65

Answer:  1.9

Step-by-step explanation:

You want to multiply 9x10 which is 90.

Then you want to add 44+pi

now pi can be shown as 3.14 or 22 over 7

in this case you want to add 44 + 3.14 which gives you 47.14

now you want to divide 90/47.14 which gives you 1.90920661858 or in short

1.9
