Answer: 7.29 or 7 1/4 or 29/4 (they're all equal, just rewritten)

Step-by-step explanation:

the angles are equal, so we set the equations to each other and then solve. here's my work:

12k - 9 = 8k + 20

12k (- 8k) - 9 = 8k ( - 8k) + 20

4k - 9 = 20

4k -9 ( + 9) = 20 ( + 9)

4k = 29

k = 7.29 or 7 1/4 or 29/4

Solve (x+1&lt;5) n (x-4&gt; -3).<br> A (all real numbers)<br> B [x|1 C [x|x&lt;4 or x&gt; 1)
katovenus [111]

Answer:

  1 < x < 4 . . . . {x | x < 4 <u>and</u> x > 1}

Step-by-step explanation:

We want to write the answer as a compound inequality, if possible. As it is written, we can solve each separately.

  x + 1 < 5

  x < 4 . . . . . . . subtract 1

__

  x -4 > -3

  x > 1 . . . . . . . add 4

So, the solution is ...

  (x < 4) ∩ (x > 1) . . . . . . the intersection of the two solutions

As a compound inequality, this is written ...

  1 < x < 4

Linn plans to wallpaper the 4 walls in her bedroom. The measurements are 9’ by 11’ by 8’. How many single rolls of wallpaper sho
Ann [662]

Answer: There are 4 rolls she should buy.

Step-by-step explanation:

Since we have given that

Length of wall = 9 feet

Width of wall = 11 feet

Height of wall = 8 feet

As we know the formula for "Area of four walls ":

Area=2(l+b)h\\\\Area=2(9+11)\times 8\\\\Area=2\times 20\times 8\\\\Area=320\ ft^2

Area of each single roll covers = 72 square feet

So, Number of single rolls of wallpaper is given by

\frac{\text{ Area of 4 walls}}{\text{ Area of single roll}}\\\\=\frac{320}{72}\\\\=4.44\\\\=4

Hence, there are 4 rolls she should buy.
