Answer:

27

Step-by-step explanation:

3(6)=18

18+9=27

Answer:

27

Step-by-step explanation:

You would use PEMDAS to solve this equation, P (parenthesis) E (exponates)  M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication?  Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.

Hope this helps!

Answer:

Question 3

C. [tex] y-9 =1/2(x-1)[/tex]

Question 4

D. [tex] y+5 =3(x+2)[/tex]

Step-by-step explanation:

Question 3:

Equation of line in point slope form is given as:

[tex] y-y_1 =m(x-x_1)[/tex]

Plug m = 1/2, [tex] x_1 = 1, \:y_1 = 9 [/tex] in the above equation, we find:

[tex] y-9 =1/2(x-1)[/tex]

This is the required equation of the line.

Question 4:

Equation of line in point slope form is given as:

[tex] y-y_1 =m(x-x_1)[/tex]

Plug m = 3, [tex] x_1 = - 2, \:y_1 = - 5[/tex] in the above equation, we find:

[tex] y-(-5) =3[x-(-2)][/tex]

[tex] y+5 =3(x+2)[/tex]

This is the required equation of the line.

Answer:

2

Step-by-step explanation:

The first step is to convert the equation to slope-intercept form (y = mx+b).

2y+6 = 4x

2y+6-6 = 4x-6

2y = 4x-6

2y/2 = 4x/2-6/2

y = 2x-3

In slope-intercept form (y = mx+b), m is the slope. 2 is m in the equation, so therefore it is the slope.

Answer:The new cost per person= $19 when there are 12 people

Step-by-step explanation:

Step 1

Let Number of people be rep as N

And Cost per person = C

such that the relationship of  number of people which varies inversely with the cost per person is given as

N∝ 1/C

Introducing constant of proportionality, k, we have that

N= K/C

such that when there were 4 people the cost per person was $57, K would be

N= K/C

4 = K /57

k= 57 X 4

k=228

Step 2

Therefore If the number of people changed to 12, cost per person would be

N= K/C

12= 228 / C

C= 228/12

C= 19

The new cost per person= $19 when there are 12 people

The missing decimal number to decrease by 14% is 0.86.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Percent= 14%

Now,

14% is equivalent to 0.14 as a decimal, and to decrease by 0.14 we need to subtract 0.14 from 1, which gives 0.86. So multiplying by 0.86 is the same as decreasing by 14%.

Therefore, by algebra the answer will be 0.86.

Answer:

Your answer is 37

Step-by-step explanation:

Caanan is 62 miles away and since he drives at 50 miles per hour, and if it is 2:30 then 30 minutes is half a hour, which means you divide 50 in half by 2 and get 25. After you do that then you subtract 62 and 25 to get your answer 37. Have a good day!!! :)

Answer:

17t+9

Step-by-step explanation:

Step-by-step explanation:

Since y= -7x you will want to substitute the y in the other equation.

2x -(-7x) = -9

2x + 7x = -9

9x = -9

so x will be -1

y= -7(-1)

x= -1

y= 7

Answer:

x = -1 , y =7      (-1,7)

Step-by-step explanation:

[tex]y=-7x\\2x-y = -9\\[/tex]

[tex]2x+7x = -9[/tex]

[tex]2x+7x = 9x\\[/tex]

[tex]9x = -9\\[/tex]

[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]

[tex]x = -1\\[/tex]

[tex]y = -7(-1)\\y = 7[/tex]

Answer:

Jeremy constructed this solid by combining two rectangular prisms and a square pyramid.

A rectangular prism with a length of 6 meters, width of 14 meters, and height of 2 meters. A rectangular prism with a length of 5 meters, width of 8 meters, and height of 3 meters. A square pyramid with a base of 6 meters by 6 meters and triangular sides with a height of 7 meters.

What is the surface area of this figure?

_____________ square meters

320

322

√368

386

Step-by-step explanation:

it was that because you have to figure out the numbers and multiply all the number and you get the number 368

Answer:

368

Step-by-step explanation:

Answer:

416 in²

Step-by-step explanation:

Given that:

Height. h = 4 in

Length = 12 in

Width = 10 in

The surface area of a rectangular prism is obtained using the relation :

Surface Area, S = 2(lw + lh + wh)

S = 2[(10*12) + (10*4) + (12*4))

S = 2(120 + 40 + 48)

S = 2(208)

S = 416 in²

Answer:

X = 3

Step-by-step explanation:

First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.

5x + 2 = 17

Then Solve For X

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide by 5

X = 3

Check your answer

5(3) +2 = 17

15 + 2 = 17

17 = 17

It is correct!

Answer:

area = 2106

perimeter = 210

Step-by-step explanation:

area = length x width

(for this specific problem and since the shape is a rectangle)

perimeter = length + length + width + width

Answer:

A = 2106 yd^2 P = 210 yd

Step-by-step explanation:

PART A:

A = l x w

A = 78 x 27 = 2106 yd^2

P = l + w + l + w = 78 + 27 + 78 + 27 = 210 yd

PART B:

area

PART C:

Answer:

49°

Step-by-step explanation:

First, solve for x.

3x-7+2x+17=90

5x+10=90

5x=80

x=16

Then put 16 in for x.

2(16)+17=

32+17=49
