Carter shares his post with 10 friends who each share the post with 2 friends a day
b) write an exponential function to show the growth of Carter’s social media post

Answer:

a=$10

c=$3

Step-by-step explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

so

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence,  the system of equations

6a+2c=66------1

5a+4c=62-------2

solving simultaneously

6a+2c=66------1 x2

5a+4c=62-------2 x1

  12a+4c=132

 -5a+4c=62

   7a=70

divide both sides by 7

a=$10

put  a=70 in 1

6(10)+2c=66------1

60+2c=66

2c=66-60

2c=6

c=$3

Answer:

-1.8f - 19

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

For the lines to be parallel, then

(8x - 31) and (6x + 3) are alternate angles and congruent, then

8x - 31 = 6x + 3 ( subtract 6x from both sides )

2x - 31 = 3 ( add 31 to both sides )

2x = 34 ( divide both sides by 2 )

x = 17

Answer:

The correct approach is "a simple random sample".

Step-by-step explanation:

Some other four approaches do never use any of certain characteristics. So that is indeed the best decision.

Answer:

12249580

Step-by-step explanation:

Answer:

X=6

Step-by-step explanation:

5(x-1)+3x=7(x+1)

5x-5+3x=7x+1

8x-5=7x+1

8x-7x=1+5

X=6

So the answer is X=6

Answer:

2

Step-by-step explanation:

You know that -3 is smaller than 0 so you have to add 3 to get it to 0 then you get 2 more so you add 0 and 2 together to get 2.

Answer: 17/18

Step-by-step explanation: Multiply the amount of containers and the amount of cups in each container. Subtract 3. This is 51 out of 54, simplify this and get 17 out of 18.

Answer:

the answer is 1/18

Step-by-step explanation:

6×9=54-3=51.

One third and two thirds are too large for the amount he ate, so is 17/18s.

Answer: I THINK it’s A

Step-by-step explanation:

This system can be solved for x by elimination.

[tex]6x - 3y = 15\\ x + 3y = -8\\\\7x = 7\\\\x = 1[/tex]

Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.

[tex]1 + 3y = -8\\\\3y = -9\\\\y = -3[/tex]

Now, we have our solution.

[tex](1, -3)[/tex]

Answer:

(1,-3)

Step-by-step explanation:

6x-3y=15

substitute x with 1 and y with -3

6(1)-3(-3)=15

6+9=15 so that's true

x+3y=-8

again substitute x with 1 and y with -3

(1)+3(-3)= -8

1-9=-8

-8=-8 and that's true

hope i helped

Fraction: [tex]\frac{27}{8}[/tex]

Mixed Number: [tex]3\frac{3}{8}[/tex]

Step-by-step explanation:

We know how much strawberry jam there is, which is 3/4 of a jar. But we need to find how many jars the raspberry jam can fill. We are told that it is      4 1/2 times as much as the strawberry jam. So, you mulitly 3/4 and 4 1/2 to get [tex]\frac{27}{8}[/tex] or [tex]3\frac{3}{8}[/tex].

ANSWER: [tex]\frac{27}{8}[/tex] or [tex]3\frac{3}{8}[/tex].

Hope this helps and answers your question! :)

Answer:

B

Step-by-step explanation:

The options in the question and the number line are shown in the image attached.

From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;

Temperature at 7:00 a.M - Temperature at 1:00 p.M

We can see from the number line that the temperature at 7:00 a.M = -4

Temperature at 1:00 p.M = 16

difference between the two temperatures = ∣(-4) - 16∣ = 20

Answer:

Remove parentheses.

y-10=-3\times -2y−10=−3×−2

2 Simplify 3\times -23×−2 to -6−6.

y-10=-(-6)y−10=−(−6)

3 Remove parentheses.

y-10=6y−10=6

4 Add 1010 to both sides.

y=6+10y=6+10

5 Simplify 6+106+10 to 1616.

y=16y=16

Answer:

B. [tex] n = 16p [/tex]

Step-by-step explanation:

number of ounces = n

number of pounds = p

There are 16 ounces in 1 pounds (unite rate: 1 pounds = 16 ounces)

Therefore, there would be n ounces in p pounds

Set a proportion to find n.

16 : 1 = n : p

[tex] \frac{16}{1} = \frac{n}{p} [/tex]

Multiply both sides by p

[tex] \frac{16}{1} \times p = \frac{n}{p} \times p [/tex]

[tex] \frac{16 \times p}{1} = n [/tex]

[tex] 16p = n [/tex]

[tex] n = 16p [/tex]

Answer:

B. 295,35 sq ft

Step-by-step explanation:

We are told that the outside dimensions of a living room are 13' 0" x 22' 0".

Since the wall has a thickness of 5 1/8", then the internal dimensions are;

Length = 22' 0" - 5⅛" - 5⅛" = 21' 1¾"

Width = 13' 0" - 5⅛" - 5⅛" = 12' 1¾"

The floor area will be length × width.

So let's convert length and width to feet

Length = 21' 1¾" = 21.1458 ft

Width = 12' 1¾" = 12.1458 ft

Area of floor required = 21.1458 × 12.1458 = 256.83

Allowing 15% for waste gives us;

Area provided = 256.83 × 1.15 = 295.35 Sq.ft

Answer:

7

Step-by-step explanation:

We have that x1=−1, y1=5, x2=3, y2=7.

Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.

Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).

b=5−(12)(−1)=112

Finally, the equation of the line can be written in the form y=b+mx:

y=112+x2

Answer:

x = 8

Step-by-step explanation:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

So,

[tex] \rm \longrightarrow 45 \degree + 80 \degree + (9x - 17) \degree = 180 \degree \\ \\ \rm \longrightarrow 125 + 9x - 17 = 180 \\ \\ \rm \longrightarrow 108 + 9x = 180 \\ \\ \rm \longrightarrow (108 - 108) + 9x = 180 - 108 \\ \\ \rm \longrightarrow 9x = 72 \\ \\ \rm \longrightarrow \dfrac{9}{9} x = \dfrac{72}{9} \\ \\ \rm \longrightarrow x = 8[/tex]

Answer:

  (x, y) = (1, -1)

Step-by-step explanation:

The augmented matrix of coefficients for these equations is ...

  [tex]\left[\begin{array}{cc|c}2&-5&7\\-2&4&-6\end{array}\right][/tex]

The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...

  [tex]\left[\begin{array}{cc|c}1&0&1\\0&1&-1\end{array}\right][/tex]

This tells you the solution is (x, y) = (1, -1).
