Rosa says 4x and -6x are like terms, so they can be combined. Tiffany says 5a and 5b are like terms, so they can be combined. Is Rosa correct? Is Tiffany correct? Why or why not?
please help =)

Answer:

85° and 95°

Step-by-step explanation:

Given that , x and x + 10 are a pair of angles .

=> x + x + 10° = 180°

=> 2x = 180° -10°

=> 2x = 170°

=> x = 170°/2

=> x = 85° .

Answer:

NOT 24/25 and NOT -4/5

Step-by-step explanation:

took the quiz

If cos(x) = 3/5 and sin x < 0, sin(2x) is equal to -24/25 as a fraction in simplest terms.

To find sin(2x), we can use the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

Given:

cos(x) = 3/5

sin(x) < 0

We need to determine sin(x) based on the given information.

Using the Pythagorean identity, sin^2(x) + cos^2(x) = 1:

[tex](sin(x))^2 + (cos(x))^2 = 1\\(sin(x))^2 + (3/5)^2 = 1\\(sin(x))^2 + 9/25 = 1\\(sin(x))^2 = 1 - 9/25\\(sin(x))^2 = 16/25[/tex]

sin(x) = -4/5

Now we can  the values into the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

sin(2x) = 2 * (-4/5) * (3/5)

sin(2x) = (-8/5) * (3/5)

sin(2x) = -24/25

Therefore, sin(2x) is equal to -24/25 as a fraction in simplest terms.

Answer:

Find the percentage of the original or real number.

Multiply the final number by 100.

Divide the result of the multiplication by the percentage.

Have a great day

The proportion of the original or true number is then added 100 to the final figure.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let's suppose it is required to find the x percentage of y:

First step:

= x% of y

Second step:

= (x/100)y

Third step: Divide x by 100

= 0.01xy

Fourth step: Multiply the remaining term(0.01x and y).

= 0.01xy

The fifth step: Round off if required

= 0.01xy %

Calculate the proportion of the original or true number.

Add 100 to the final figure.

Subtract the percentage from the multiplication result.

Thus, the proportion of the original or true number is then added 100 to the final figure.

Answer:

(3, - 1 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = 9 → (1)

x + 2y = 1 → (2)

Rearrange (2) expressing x in terms of y by subtracting 2y from both sides

x = 1 - 2y → (3)

Substitute x = 1 - 2y into (1)

2(1 - 2y) - 3y = 9

2 - 4y - 3y = 9

- 7y + 2 = 9 ( subtract 2 from both sides )

- 7y = 7 ( divide both sides by - 7 )

y = - 1

Substitute y = - 1 into (3) for corresponding value of x

x = 1 - 2(- 1) = 1 + 2 = 3

solution is (3, - 1 )

Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Pick any two corresponding points from the table

So, we have:

[tex](x_1,y_1) = (8,1.21)[/tex]

[tex](x_2,y_2) = (12,1.63)[/tex]

So:

[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{1.63 - 1.21}{12 - 8}[/tex]

[tex]m =\frac{0.42}{4}[/tex]

[tex]m =0.105[/tex]

The linear equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 0.105 * (x - 8) + 1.21[/tex]

Open bracket

[tex]y = 0.105x - 0.84 + 1.21[/tex]

[tex]y = 0.105x + 0.37[/tex]

To get the length closest to 4.2lb,

we set [tex]y = 4.2[/tex]

Then solve for x

So, we have:

[tex]y = 0.105x + 0.37[/tex]

[tex]4.2 = 0.105x + 0.37[/tex]

Collect like terms

[tex]0.105x= 4.2 - 0.37[/tex]

[tex]0.105x= 3.83[/tex]

Solve for x

[tex]x= 3.83/0.105[/tex]

[tex]x\approx 36.5[/tex]

The ratio of the number of ham slices to the number of turkey slices is 2:3.

Hence:

Ham slices: Turkey slices

2:3

Sum of proportion = 2 + 3 = 5

Ratio of turkey slices = 3

Ratio of the total of ham and turkey slices = sum of proportion = 5

Therefore, the ratio of the number of turkey slices to the total of ham and turkey slices is

Answer:

The IQR (interquartile range) of the data set represented by this box plot is 22 units.

Step-by-step explanation:

Each number of the data set represented as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is called the minimum. The highest number there (the last number), 75, is called the maximum. The second number there, 45, is called the lower quartile. The third number there, 50, is called the median or middle quartile. The fourth number there, 67, is called the higher quartile. In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.

67 (highest quartile) - 45 (lower quartile) = 22 (interquartile range)

Therefore, the IQR (interquartile range) of the data set represented by this box plot is 22 units.
