arcade game costs $2. Which of the following could be used to determine the number of arcade games Pedro can
play if he plays one round of mini-golf?

Answer:

4

The dot in the middle simply means multiplication. 4.4 is 16. 16/4 is 4

Answer:

2x-3=7 /×3

2x=3+7

2x=10 /÷2

x=5

Answer:

Step-by-step explanation:

2x - 3 = 7                         Add 3 to both sides

2x - 3+3 = 7 + 3                Combine

2x = 10                              Divide by 2

2x/2 = 10/2                       Combine

x = 5

These types of equations all follow the same pattern. The look like

ax + b = c                         You have to isolate the x so add b if b is minus or you subtract b if b is plus. Notice that b was minus in your question. So Add

Now you you have

ax  =  c - b                      That always happens. The x is isolated if you deal with b first. Now all you need to do is divide by a.

x = (c - b)/a

Try a couple

3x -4 = 5                       The answer is 3

5x + 2 = 27                   the answer is 5

Hope this helps

Step-by-step explanation:

what we trying to find the value of x and y

20x+6=y

x intercept,y=0

20x+6=0-6

20x/20=-6/20

×=-0.3

y intercept,x=0

20(0)+6=y

0+6=y

6=y

(-0.3,0)

19x+7=y

y intercept,x =0

19(0)+7=y

0+7=y

7=y

x intercept,y=0

19x+7=0-7

19x=-7

19x/19=-7/19

x=-0.37

Answer:

- 9

Step-by-step explanation:

We require

- 15 , m₁, m₂, m₃, 9

The average of the end values gives m₂ , that is

m₂ = [tex]\frac{-15+9}{2}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

Similarly, the average of - 15 and m₂ gives m₁

m₁ = [tex]\frac{-15-3}{2}[/tex] = [tex]\frac{-18}{2}[/tex] = - 9

The first arithmetic mean m₁ = - 9

Answer: 16

Step-by-step explanation:

Standard deviation is 2

Margin error for the problem is 1

Probability 95%, that means thet the siginficance level α is 1 – p

α = 1 – 0.95 = 0.05

margin of error (ME) can be defined as follows

ME = Z(α/2) * standard deviation/ √n

Where n is the sample size

Z(0.05/2) = Z(0.025)

Using a z table Z = 1.96

Now, replacing in the equation and find n

1 = 1.96 * 2/ √n

1 = 3.92 / √n

√n = 3.92

n = 3.92^2

n = 15.36 = 16

i hope this work for you

Answer:

1/6

Step-by-step explanation:

firstly the question is a probability without replacement because the chocolate are eaten after being picked .

next sum the total chocolate in the bag (4+5)=9

now probability is possible outcome over total outcome.

P(a)and p(b) =p(a)xp(b)

p(a)=4 /9

p(b)=3/8 ... because there will be 3 milk chocolate and 5dark chocolate left

hance P=(4/9)(3/8)

=1/6

Answer:

62

Step-by-step explanation:

Answer: Width = 49meters; Length = 59meters

Step-by-step explanation:

Let the width be represented by x

The length will be (x+10)

Perimeter = 2(length+breadth)

Perimeter= 2(x + x + 10)

Perimeter = 2(2x + 10)

216 = 4x + 20

4x = 216 -20

4x = 196

x = 196/4

x = 49

Width = 49meters

Length = x+10

Length = 49 + 10

Length = 59meters

Hey there!

5 = 1/4(a + 5)

1/4(a + 5) = 5

1/4(-4 + 5) = 5

1/4(-4) + 1/4(5) = 5

1/4(-4) + 1/4(5)
= -1 + 5/4

= -1/1 + 5/4

= 1/4

1/4 ≠ 5
0.25 ≠ 5

Thus, your answer should most likely be: [FALSE] because the numbers are NOT equivalent to each other.

“a” should equal to “15”

Good luck on your assignment & enjoy your day!

Answer:

$8.50/h

Step-by-step explanation:

I am unsure of the - in the equation. This should be 4h+50+6h+70=M

then we would set the equation equal to the $205

205=4h+50+6h+70

if we simplify we have

205=10h+120

then we would get the h by itself and we get

205-120=10h

85.00=10h

85.00/10=10h/10

8.50=h

Answe: 3rd one

Answer:

bottom right due to X being grater then 2 on the X-axis

Answer:

2

Step by step explanation:

Given: The average mass of all the students in the class was 35.1 kg. After 1 student left the class, whose mass is 32.3kg, the average mass of the remaining students became 36.3kg, how many students were there in the class room now?

Find out: how many students were there in the class room after one student left

Solution: Let the total number of remaining student be= n

Let the total number of remaining student be= nAnd the sum of mass of all the students be = x kg

So,

[tex] \frac{x}{n + 1} = 35.1[/tex]

Make x the subject of formula

[tex]--› \: x = 35.1(n + 1)[/tex]

And

[tex]--› \: \frac{x - 32.3}{n} = 36.3[/tex]

[tex]--›x - 32.3= 36.3n[/tex]

[tex]--› \: 35.1(n + 1) - 32.3 = 36.3n[/tex]

[tex]--› \: 35.1n + 35.1 - 32.3 = 36.3n[/tex]

[tex]--› \: 2.8 = 1.2n[/tex]

divide both side by n

[tex]n = \frac{2.8}{1.2} [/tex]

N = 2.333

so total number of students remaining is 2

Answer:

2.25 seconds, 86 feet.

Step-by-step explanation:

No idea where the r, second is, so I'm assuming that t is time in seconds.

Because this is a perfect parabola, we can find the zeroes (the places where the y value is 5, because that's where the teacher is launched from) and then get the middle of those 2 points.

First let's make the a term of this equation be positive so multiply everything by minus one.

16t^2-72t-5

After that, let's factor this (I won't go into details about this, you should already know how to do this if your asking this question)

we get t(t - 4.5) = 5

So the 2 x values are 0 and 4.5, and the whole flight time of the teacher is 4.5 seconds.

The half way between that is 2.25, and then we can plug that time back in to the equation to get a y value of 86.

Answer:

There are 364,000 people in the Air Force.

Step-by-step explanation:

Percentages

The N% of a number M is calculated by:

[tex]\displaystyle \frac{N*M}{100}[/tex]

For example, 15% of 280 is

[tex]\displaystyle \frac{15*280}{100}=42[/tex]

We know the total amount of people serving as of January is estimated to be 1,400,000 people and that 26% of them are serving in the Air Force.

Compute 26% of 1,400,000:

[tex]\displaystyle \frac{26*1,400,000}{100}=364,000[/tex]

There are 364,000 people in the Air Force.

OK I'm just gonna guess this but I think its B. 130? Cuz honestly it makes the most sense.

Step-by-step explanation:

If it's wrong sorryyyy...

To solve algebraic equations, we must combine like terms and perform inverse operations on both sides of the equal sign to isolate the variable.

Inverse operations help us cancel values out.

[tex]- 4 a - 2 a = - 18[/tex]

⇒ First, combine like terms:

[tex]- 6a = - 18[/tex]

⇒ a is being multiplied by -6. To isolate a, divide both sides by -6:

[tex]\dfrac{- 6a}{-6} = \dfrac{- 18}{-6}\\\\a=3[/tex]

a = 3

Answer:

a=3

Step-by-step explanation:

-4a-2a=-18

-6a= -18

Divide both sides by -6

-6a/-6=-18/-6

a=3
