Ryan scored 12 more points than Alex on a video game. If together they scored 214 points, how many points
does each person score?

Answer:

1.

x=# of purple marbles

y=# of yellow marbles

y=3x

y+x=164

3x+x=164

4x=164

x=41

There are 41 purple marbles and 41*3=123 yellow marbles.

2.

L=large fries

H=hamburger

H=1.15+L

2H+L= 8.60

2.3+2L+L=8.60

2.3+3L=8.60

3L=6.3

L=2.1

A large fries costs $2,1 while a Hamburger costs 1.15+2.1=$3.25.

Answer:

$450

Step-by-step explanation:

let m represent the amount of money munah has

That means elias would have 3 * m or 3m dollars.

Then, you have m + 60 = 3m - 240

solve:

[tex]m + 60 = 3m -240\\300 = 2m\\m = 150[/tex]

So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450

Answer:

y=2x+5

Step-by-step explanation:

I used 2 as the slope bc we were given an equation above: y=2x-4. Since parallel lines have same slopes and different y-intercepts, hence, I easily got 2 as the slope.

Step-by-step explanation

that corner is same as the one across it sorry I don’t know how to explain it very well but it’s Angel is linear to the one across it mean it’s the same

Answer:

C. 130 degrees

Step-by-step explanation:

The total degrees of the interior angels of a six sided ploygon is 720, so all you need to do is add the shown angles together and subtract that number from 720:

130 + 130 + 130+ 100 + 100 = 590

720 - 590 = 130

The Moon exerts its force of gravity; since it's smaller and lighter than Earth, we would discover we weigh around a sixth of our weight on Earth if we could weigh ourselves on it. One could ask why the Moon doesn't fall on Earth as an apple from the tree.

Answer:

  x = 12

Step-by-step explanation:

Segment lengths of each chord have the same product.

  (x -2)(x +6) = 9×20

  x² +4x -12 = 180

  x² +4x +4 = 196 . . . . . add 16 (complete the square)

  (x +2)² = 14²

  x +2 = 14 . . . . . . . . . . . positive root is the only one useful

  x = 12

Answer:

Step-by-step explanation:

8) B(x) = [tex]5^{x +1}[/tex]

[tex]5^{x + 1} = 3125 \\\\5^{x +1} = 5^{5}\\\\[/tex]

Compare the exponents,

x + 1 = 5

   x = 5 - 1

   x = 4

[tex]10)2^{x-4}=512\\\\2^{x -4} = 2^{9}\\\\[/tex]

Compare exponents,

x - 4 = 9

    x = 4 + 9

    x = 13

Step-by-step explanation:

y/2 is what we need. If y is 6. Then 6/2=3.

Answer:

14. (-8, 12)   15. (6, 7)

Answer:

- True

- True

- False

- True

Step-by-step explanation:

- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system

- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.

[tex]-2(-3)+(-3)=3[/tex] (Correct)

[tex]3(-3)+2(-3)=-15[/tex] (Correct)

- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.

- The solution can be written as one value since x = y = -3. Therefore, this statement is true.

Answer:

1.586 x 10³

Step-by-step explanation

900.000 + 50.000 + 9.000 + 600 + 20 + 7=1586

standard form:

1.586 x 10³

Answer:

18 sides.

Step-by-step explanation:

The interior and exterior angles sum to 180 so:

       I + E = 180

also  I - E = 140       (given)

So, adding to eliminate E:

      2I = 320

I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.

Since the sum of all exterior angles in a polygon = 360 degrees

- the number of sides = 360 / 20 = 18.
