Many times does 5 go into 125

Answer: X=2.7

Step-by-step explanation:

25*2-8x=12x-4

50-8x = 12x-4

subtract 50 from both sides

-8x = 12x-54

subtract 12x from both sides

-20x= -54

divide both sides by -20

X=2.7

Answer:x=2/5

Step-by-step explanation:

25x2-8x=12x-4

25x2-8x-12x+4=0

25x2-20x+4=0

25x2-10x-10x+4=0

5x(5x-2)-2(5x-2)=0

(5x-2)(5x-2)=0

5x-2=0 and 5x-2=/

5x=2 and 5x=2

X=2/5

Dot bikes 7m+10 miles this week.

Step-by-step explanation:

Distance of one loop = m miles

Distance of 2 loops = 2m

Distance of 3 loops = 3m

Distance covered on Sunday = 10 miles

Total distance = Monday + Wednesday + Friday + Sunday

Total distance = 2 loops + 2 loops + 3 loops + 10 miles

Total distance = 2m + 2m + 3m + 10

Total distance = (7m+10) miles

The third dot

Step-by-step explanation:

I did this question before :)

Answer:

Step-by-step explanation:

Let t and f represent the numbers of three- and five-pound weights. The problem statement tells us ...

  f + t = 60

  f - t = 10

Adding these two equations, we get ...

  (f +t) +(f -t) = (60) +(10)

  2f = 70 . . . . . eliminate parentheses

  f = 35 . . . . . . divide by 2

She has 35 5-lb weights, and 25 3-lb weights.

Let's label the number you're trying to find x. You have to set up a system of equations.

1. Five times a number can be labeled as 5x.

2. Subtracted from 20 gives us 5x-20.

3. The problem says this is the same as simply tripling the original number. So set the first equation equal to 3x.

4. 5x-20=3x

5. Move like terms onto the same side. We can do this by subtracting 3x from both sides and adding 20 to both sides.

6. 5x-3x=20

7. 2x=20

8. Divide both sides by 2 to get x by itself.

Answer: x=10

The number is 2.5.

Let the number is = x.

According to the question:

20 - 5x = 3x

Add 5x.

20 = 5x + 3x

20 = 8x

Divide by 8.

x = 20/8 = 2.5

Answer:

10 black- 10/20 - 50%

8 red- 8/20 - 40%

2 white - 2/20 -10%

Step-by-step explanation:

The total number of balls = 10 + 8 + 2 = 20 balls

probability of black balls = 10/20 = 50%

probability of red balls = 8/20 = 40%

probability of white balls = 2/20 = 10%

the three probabilities:

probability that the ball is one of the three colors = (10/20) + (8/20) + (2/20)

                                                                              = 1 = 100%

The Town Recreation Department ordered 76 baseballs and 24 bats.

Given that, the total number of baseballs = 100, the total purchase = $822, cost of each baseball = $4.50 and the cost of each bat = $20.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let the number of baseballs be x and the number of bats be y.

Now, the total number of items = The number of baseballs + The number of bats

⇒ 100=x+y ------(I)

Total amount = 4.50x+20y

⇒ 4.50x+20y = 822 ------(II)

Solve the obtained equations:

Put x=100-y in the equation 4.50x+20y = 822

We get, 4.50(100-y)+20y = 822

⇒ 450-4.50y+20y=822

⇒ 15.5y=372

⇒ y=372/15.5

⇒ y= 24

So, x+y =100

⇒ x=100-24=76

Therefore, the Town Recreation Department ordered 76 baseballs and 24 bats.

Answer:

Explanation:

The complement of a subset is the subset of elements that are not in the given subset.

You must know which numbers the spinner has.

Assuming the spinner has the numbers 1, 2, 3, 4, the complement of spinning any number less than 3, is spinning a number that is not less than 3.

Then, that is spinning a number that is equal to or greater than 3.

The numbers that are equal to  or greater than four, for a spinner that has the numbers 1, 2, 3, and 4 are 3 and 4.

Thus, the complement of spinning any number less than 3 is spinning a three or a four.

Answer:

Center (h, k) = (0, 6)

Radius, r = 3 units

Step-by-step explanation:

The given equation of the circle is: [tex]$ x^2 + y^2 + 12y + 27 = 0 $[/tex]

STEP I: Move the constant term to the right hand side.

To do that we subtract 27 on both the sides, we get:

[tex]$ x^2 + y^2 + 12y = -27 $[/tex]

STEP II: Divide the co - effecient of 'x' by 2 and square it.

Here there is no 'x' term. Its co-effecient is 0.

STEP III: Add the result on both sides.

Since, we got 0 in the previous step, there would no change in the equation

STEP IV: We repeat the process for 'y'.

Here, the co-effecient of 'y' is: 12.

Dividing by 2 and squaring it will yield:

[tex]$ \frac{12}{2} = 6; \hspace{5mm} 6^2 = 36 $[/tex]

STEP V: Adding 36 to both the sides of the equation, it becomes:

[tex]$ x^2 + y^2 + 12y + 36 = -27 + 36 $[/tex]

[tex]$ \implies x^2 + y^2 + 12y + 36 = 9 $[/tex]

We have arrived at perfect squares.

STEP VI: Write in the form of perfect squares.

[tex]$ (x - 0)^2 + (y - 6)^2 = 3^2 $[/tex]

STEP VII: Compare it with the standard form.

[tex]$ (x - h)^2 + (y - k)^2 = r^2 $[/tex]

We get: The centre of the circle: (h, k) = (0, 6) and

the radius of the circle, r = 3 units.

Two sevenths over two fifths = five over seven mile per hour

The unit rate is 5 over 7 miles per hour

Solution:

Given that, Suzanna walked two over seven of a mile in two over five of an hour

We have to find the unit rate in miles per hour

Unit rate means number of miles covered in 1 hour

From given information,

Two over seven of a mile in two over five of an hour

Which means,

[tex]\frac{2}{7} \text{ miles } = \frac{2}{5} \text{ hour }[/tex]

[tex]\text{ So she covered } \frac{2}{7} \text{ miles in } \frac{2}{5} \text{ hour }[/tex]

To find for number of miles covered in 1 hour, divide the [tex]\frac{2}{7} \text{ by } \frac{2}{5}[/tex]

[tex]\text{Unit rate in miles per hour } = \frac{\frac{2}{7}}{\frac{2}{5}}\\\\\text{Unit rate in miles per hour } = \frac{2}{7} \times \frac{5}{2} = \frac{5}{7}[/tex]

Two sevenths over two fifths = five over seven mile per hour

Thus unit rate is 5 over 7 miles per hour

Answer:

two sevenths over two fifths = five over seven mile per hour

Step-by-step explanation:

two sevenths over two fifths = five over seven mile per hour

Teresa served 33 orders and Charlie served 24 orders and Justin served 96 orders

Solution:

Let "a" be the orders served by Teresa

Let "b" be the orders served by Charlie

Let "c" be the orders served by Justin

Teresa, Charlie, and Justin served a total of 153 orders

Therefore,

a + b + c = 153 -------- eqn 1

Justin served 4 times as many orders as Charlie

Orders served by Justin = 4( orders served by Charlie )

c = 4b ---------- eqn 2

Teresa served 9 more orders than Charlie

orders served by Teresa = 9 + orders served by Charlie

a = 9 + b ----------- eqn 3

Let us solve eqn 1 and eqn 2 and eqn 3

Substitute eqn 2 and eqn 3 in eqn 1

9 + b + b + 4b = 153

9 + 6b = 153

6b = 153 - 9

6b = 144

b = 24

Substitute b = 24 in eqn 3

a = 9 + 24

a = 33

Substitute b = 24 in eqn 2

c = 4(24)

c = 96

Thus Teresa served 33 orders and Charlie served 24 orders and Justin served 96 orders

Answer:

1.75, 0.4375

Step-by-step explanation:

Note there is a common ratio between consecutive terms, that is

r = 28 ÷ 112 = 7 ÷ 28 = 0.25

Thus the sequence is geometric.

To obtain a term in the sequence multiply the previous term by 0.25

7 × 0.25 = 1.75

1.75 × 0.25 = 0.4375

The next 2 terms in the sequence are 1.75, 0.4375

Answer: 10 Acme and 15 Zenith.

She can buy 10 Acme and 15 Zenith calculators.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

A math teacher wants to buy 25 new scientific calculators for the classroom.

Acme and Zenith makes two different type of calculators.

Acme calculators cost $15 each.

Zenith calculators cost $12 each.

The math teacher has $330 to spend.

Let x represents the number Acme calculators and y represents Zenith.

Now, we have the system of equations,

x + y = 25

So, y = 25 - x

And 15x + 12y = 330

Substituting the value of y,

15x + 300 - 12x = 330

3x = 330 - 300

3x = 30

x = 10

So, y = 15

Therefore, 10 Acme and 15 Zenith calculators.
