Mini golf costs  $10 per round and batting cages cost $2.5 each turn.

Step-by-step explanation:

mini golf ([tex]m[/tex])

batting caves ([tex]b[/tex])

Sylvester:

[tex]5m+4b=60[/tex]

Lin

[tex]3m+6b=45[/tex]

System of equations:

[tex]$\left \{ {{5m+4b=60} \atop {3m+6b=45}} \right. $[/tex]

[tex]$\left \{ {{5m(-3)+4b(-3)=60(-3)} \atop {3m(5)+6b(5)=45(5)}} \right. $[/tex]

[tex]$\left \{ {{-15m-12b=-180} \atop {15m+30b=225}} \right. $[/tex]

[tex]18b=45[/tex]

[tex]b=2.5[/tex]

Now let's find [tex]m[/tex]

[tex]3m+6(2.5)=45\\3m+15=45\\3m=30\\m=10[/tex]

If X^2 = 4
Does X = 2 or X = -2

Answers

Answer:

Both.

Step-by-step explanation:

[tex]x^2=4[/tex]

[tex]x=\±\sqrt{4}[/tex]

[tex]x=\± 2[/tex]

Answer:

Yes

Step-by-step explanation:

If,

X² = 4

Taking square root on both sides

[tex]\sqrt{x^2} = \sqrt{4}[/tex]

So, It becomes

X = ±4

10) Two number cubes are rolled and the results are added. (There are 36 possible
outcomes.) What is the probability the sum is equal to 2?​

Answers

Answer:

2.7%

Step-by-step explanation:

The first thing to take into account, how could the sum be and the only way is that in each numerical cube, get a 1, because the other option is 2+ 0, but it is assumed that both cubes are numerical and on each side there are number.

Therefore, the probability would be that in each die 1 appears, they tell us that there are 36 possible results in the two dice and this would be 1 of those 36 results, which means that the probability would be:

1/36 = 0.027

What 2.7% means is the probability

The point (2,–5), when reflected across the origin, maps onto the point _______. answers : (–5,2) (5,–2) (–2,5) (2,5)

Answers

The points (2, -5) when reflected across the origin becomes (-2, 5)

What is reflection?

Reflection is a mathematical transformation of a shape by moving the vertices of the shape a distance equal to the distance between the line of reflection and the original point.

Other types of transformational processes are: Rotation and translation.

Analysis:

In transformation in the origin, the line of reflection is x = 0 and y = 0.

Which means both coordinates of the point would be changed.

At x = 2, 2 is 2 units from the origin. The only point which is 2 units away from the origin in the opposite side is -2.

Also at x = -5, that is 5 units away from the origin. The only point 5 units away from the origin is 5. so the new coordinate is 5.

In conclusion, the new point after reflection would be (-2, 5)

Answers

Answer:

n = - 5

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex]\frac{a^{m} }{a^{n} }[/tex] ⇔ [tex]a^{(m-n)}[/tex]

Consider the left side

[tex]\frac{y^4.y^{n} }{y^2}[/tex]

= [tex]\frac{y^{4+n} }{y^2}[/tex]

= [tex]y^{4+n-2}[/tex]

= [tex]y^{2+n}[/tex], then

[tex]y^{2+n}[/tex] = [tex]y^{-3}[/tex]

Since the bases on both sides are the same, equate the exponents

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

n = - 5

Answers

Answer: C. 42

Step-by-step explanation:

(3x + 3) is the same angle as 129.

So, you have to equal them to each other.

3x + 3 = 129

Now you solve.

Subtract 3 from each sides.

3x = 126

Divide 3 from each side.

x=42

Answer:

x = 42°

Step-by-step explanation:

J//k if the the two corresponding angles are equal

which means 3x + 3 = 129

solving 3x + 3 = 129

3x = 129 - 3

3x = 126

then

x = 126/3

 = 42°
