Hey, there!!

Let's solve it simply.

Given,

11 - 13x - 7 - 2x = 7

Simplify the like terms.

11 - 7 - 13x - 2x = 7

4 - 15x = 7.

shifting 4 in right side.

-15x =7-4

-15x = 3

Divide 3 by -15.

$x = \frac{3 }{ - 15}$

Therefore, x = (-3/15) or (-1/5).

Hope it helps....

Which of the following is the equation of a line that passes through the point (1,4) and is parallel to the x-axis A. Y=1 B. Y=4

const2013 [10]

Answer:

Step-by-step explanation:

The equation of a line parallel to the x- axis is

y = c ← standard form

Where c is the value of the y- coordinates the line passes through

here the line passes through (1, 4) with y- coordinate of 4, hence

y = 4 ← is the equation of the horizontal line

Consuelo's living room is the shape of a rectangle and has an area of 360 square feet. The width of the living room is 5/8 its l

zlopas [31]

Answer:

The answer to your question is length = 24 ft

Step-by-step explanation:

Data

Rectangular-shaped

Area = 360 ft²

lenght = x

width = 5/8x

Formula

Area = length x width

- Substitution

360 = (x)(5/8x)

- Solve for x

360 = 5/8x²

x² = 360(8)/5

x² = 2880 / 5

x² = 576

- Result

x = 24 ft

- Conclusion

The length of the living room is 24 ft and the width is 24(5/8) = 15 ft.

= The average score of Karl's first four math tests is 72 points. After the fifth and the sixth tests, his average score increas

mylen [45]

Answer:

83 points

Step-by-step explanation:

-The formula for average is given as:

$\bar X=\frac{1}{n}\sum{x_i}\\\\x_i=Individual \ Test \ scores\\n=number \ of \ scores$

Let a be his 5th score and (a+4) of the 6th

#We subtract the sum of the first 4 tests from the 6, to get the sum of the 5th and 6th tests:

$(6^{th}+5^{th})=\bar X n_6-\bar X n_4\\\\=75\times 6-72\times 4\\\\=162$

#We substitute for the 5th and 6th to solve a:

$5^{th}=a\\6^{th}=a+4\\\\a+(a+4)=162\\\\2a=158\\\\a=79\\\\6^{th}=a+4=79+4=83$

Hence, Karl score 83 points in his 6th test.
