How do i solve 15=16x-11x

1 answer:

8 0

You need to isolate x, which means you need to get it alone. 16x and 11x are like terms because they both have an x, do subtract them. 16-11=5. So 15 = 5x

Then to turn 5x into x, divide by five. This is because 5/5 is 1, and 1x is x. Divide both sides, so

X = 3

Factor Xsquared +12x+27

____ [38]

Answer:

$(x+3)(x+9)$

Step-by-step explanation:

We are given the expression $x^2+12x+27$

This means that we are looking for two numbers that would add together to give us 12 and multiply to give us 27.

The two numbers that fit this description are 3 and 9.

This means that the factored form of the expression would be

$(x+3)(x+9)$

The graph relates the number of gallons of white paint to the number of gallons of red paint Jess used to make the perfect pink.

Effectus [21]

Answer:

y = $\frac{1}{4}x$

Step-by-step explanation:

Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.

Let the number of gallons of white paint required = x

and number of gallons of red paint required = y

y ∝ x

y = kx [k = proportionality constant]

Since a point (4, 1) lies on this line,

1 = 4k

k = $\frac{1}{4}$

Therefore, equation that describes the relationship will be,

y = $\frac{1}{4}x$

Berikut ini adalah data hasil penjualan beras toko “Sukses” selama seminggu (dalam kg). 24, 23, 25, 30, 31, 23, 26, 25, 29, 27,

Gnoma [55]

The mode of the given data is 25.

<u>Explanation:</u>

24, 23, 25, 30, 31, 23, 26, 25, 29, 27, 26, 25, 26, 25, 24, 27, 28, 30, 25, 27, 30, 26

Rearranging the data in ascending order:

23, 23, 24, 24, 25, 25, 25, 25, 25, 26, 26, 26, 26, 27, 27, 27, 28, 29, 30, 30, 30, 31

Mode of a data is the number that is repeated the most number of times in the entire data set.

From the given data set, we can see that the number that is repeated the maximum number of times is 25 as 25 is repeated 5 number of times.

Thus, the mode of the given data is 25.
