how do I solve number 1?​

For a 2 step equation, I'm guessing you are talking about this kind of equations.

2x+3=5

In these equations you solve it first.

2x=2

x=1

Now to check your work you simply substitute it back in to see if the equation stands.

2*1+3=?=5

2+3=5

This equal sign stands when I substitute it back so therefore its correct.

That's what checking your work means, this is how you check your work for most solve for x problems :)

Answer:

14

Step-by-step explanation:

17 - 4 + 1 = 13 + 1 = 14

Answer:

Step-by-step explanation:

D = distance

[tex]x_{1}[/tex] = 4

[tex]x_{2}[/tex] = 17

No "y" values were given.

The distance formula:

[tex]D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}[/tex]

If we insert in the values:

[tex]D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}[/tex]

(0-0)^2 = 0 so we can just remove the last part since it's +0:

[tex]D = \sqrt{(4 - 17)^{2}}[/tex]

4 - 17 is equal to -13:

[tex]D = \sqrt{(-13)^{2}}[/tex]

Since [tex](-a)^{2} = (a)^{2}[/tex], that means that the negative 13 becomes positive

[tex]D = \sqrt{(13)^{2}}[/tex]

Now the square root and the square cancels each other out:

[tex]D = 13[/tex]

C! 10 = ∎ × 60

i know this becuase i did the equation in reverse, then used my calculator to make sure all the numbers added up.

Answer: B)

Step-by-step explanation:

First we need to find the value of the black sqaure. The value of the black square is 6 because 60 / 10 = 6. A) cannot be the answer because 6 does not equal 60. C) cannot be the answer because 10 does not equal 360. The only answer can be B) because 6 x 10 does equal 60.

Answer:  rice a

Step-by-step explanation:

convert 1/5 to a decimal .20 <.25

Bag of rice B gives more rice than bag A as per the percentage.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

Given, A shop sells two different bags of rice. Rice A has 500g plus 25% extra free and Rice B has750g plus 1/5 extra free.

For calculating the free amount of rice,

For Bag A

Frre amount of rice  = 500* 25%  = 500 *25/ 100 = 125g

For Bag B

Frre amount of rice  = 750 * 1/5 = 150g

Therefore, According to the percentage, bag B of rice contains more rice than bag A.

Step-by-step explanation:

The parent function is y = x²

If we vertically stretch it by a factor of 3, then we get to y = 3x²

So it's 3 times taller than it used to be. A point like (2,4) moves to (2,12) after applying this vertical stretch. Because it's stretched vertically, it becomes more narrow in the horizontal direction.

If we then shift that down by 2 units, then we arrive at the equation y = 3x²-2

So to summarize, we applied these two transformations:

Answer:

The answer is below

Step-by-step explanation:

A parallelogram is a quadrilateral (has 4 sides and 4 angle) with two pair of parallel and opposite sides. Opposite sides of a parallelogram are parallel and equal.

Given parallelogram ABCD:

AB = CD = 18 cm; BC = AD = 8 cm

∠P = ∠P, ∠PDA = ∠PCQ (corresponding angles are equal).

Hence ΔPCQ and ΔPDA are similar by angle-angle similarity theorem. For similar triangles, the ratio of their corresponding sides equal. Therefore:

[tex]\frac{CD}{PC}= \frac{AD}{CQ}\\\\\frac{18}{6}=\frac{8}{x} \\\\x=\frac{6*8}{18}=\frac{8}{3}\ cm[/tex]

Perimeter of CPQ = CP + CQ + PQ

15 = 6 + 8/3 + PQ

PQ = 15 - (6 + 8/3)

PQ = 6.33

∠CQP = ∠AQB (vertical angles), ∠QCP = ∠QBA (alternate angles are equal).

Hence ΔCPQ and ΔABQ are similar by angle-angle similarity theorem

[tex]\frac{AQ}{QP}=\frac{AB}{CP} \\\\\frac{AQ}{6.33} =\frac{18}{6} \\\\AQ=\frac{18}{6}*6.33\\\\AQ = 19[/tex]

[tex]\frac{BQ}{CQ}=\frac{AB}{CP} \\\\\frac{BQ}{8/3} =\frac{18}{6} \\\\BQ=\frac{18}{6}*\frac{8}{3} \\\\BQ =8[/tex]

Perimeter of BAQ = AB + BQ + AQ = 18 + 8 + 19 = 45cm

PA = AQ + PQ = 19 + 6.33 = 25.33

PD = CD + DP = 18 + 6 = 24

Perimeter of PDA = PA + PD + AD = 24 + 25.33 + 8 = 57.33 cm

Answer:

B.

Step-by-step explanation:

For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.

The dot plot is solved and Overall, house cats weigh more with less variation.

A dot plot, also known as a dot chart or dot graph, is a type of data visualization that displays the frequency of values in a dataset. It is a simple graphing technique that uses dots to represent data points on a horizontal or vertical axis.

Each data point in the dataset is represented by a dot placed above the corresponding value on the axis. If there are multiple data points with the same value, the dots are stacked vertically above that value. The resulting plot shows the distribution of data points along the axis, with the height of the stack of dots representing the frequency of each value.

Given data ,

Let the dot plot be represented as A and B

where the weights of house dogs and small dogs are plotted

Now , the median of house cats = 11

The median of small dogs = 9

Variation refers to the spread or dispersion of a set of data points. It measures how much the values in a dataset differ from the mean or from each other. There are several ways to calculate variation, including the range, variance, and standard deviation.

So , Overall, house cats weigh more with less variation.

Hence , the dot plot is solved
