Mathematics

Alright, let's solve this problem! :)

<u>First we need to subtract 5k from both sides.</u>

3k−5k>12

<u>Then we simplify 3k - 5k to -2k.</u>

-2k > 12

<u>Now we divide both sides by -2.</u>

k < -12/2

<u>Now we simplify 12/2 to 6.  </u>

k < -6

✔️Done!

Have an amazing day!

In the blueprint for A rectangular balcony is 1 inch by 1.75 inches if the actual length is 7 feet what is the perimeter
Elenna [48]

Answer:

22 feet

Step-by-step explanation:

Given

  • In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
  • The actual length(L)=7 feet

To find the actual perimeter, we need the breadth of balcony(B)

The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth

⇒

\frac{\text{length of rectangular balcony in blueprint}}{\text{breadth of rectangular balcony in blueprint}} =\frac{\text{length of rectangular balcony actually}}{\text{breadth of rectangular balcony actually}}

\frac{l}{b} =\frac{L}{B} \\B\times l=L \times b\\B= \frac{L \times b}{l}=\frac{7 \times 1}{1.75} =4

Therefore Breadth actually=4 feet

⇒Perimeter

=2\times(length+breadth)\\=2\times(7+4)\\=2\times(11)\\=22

Therefore perimeter of rectangular balcony= 22 feet

I don't know how to put this answer in.
kap26 [50]

Answer:

i \times j = k \\ j \times k = i  \: and \:  k \times i = j \\  \\ j \times i=  - k \\ k \times j =  - i \\ i \times k =  - j \\  \\  (i - k) \times (k - j) = \\ i \times k - (i \times j) -  \\ (k \times k)  + (k \times j) \\ note  \\ \: i \times i = j \times j = k \times k = 0

3. A recipe calls for 2 cups of sugar to make 2 dozen cookies. Use the proportion to calculate how much sugar is needed to make
vova2212 [387]

Answer:

c. 6 cups

Step-by-step explanation:

The proportion is 1 cup of sugar for 1 dozen cookies (1/1). So if you multiply the denominator by 6 you must multiply the numerator by 6, and 6*1=6. Therefore you need 6 cups of sugar to make 6 dozen cookies.
