Answer:

<u>p = -2q</u>

Step-by-step explanation:

<u>Given</u>

There is no solution.

  1. Slopes are equal

  • px + 4y = 10
  • 4y = -px + 10
  • y = -p/4 + 5/2

  • qx - 2y = 1
  • 2y = qx - 1
  • y = q/2 - 1/2

<u>Equating the slopes</u>

  • -p/4 = q/2
  • -p = 2q
  • <u>p = -2q</u>

Approximately how many times greater is 8.5×108 than 3.4×105 ? A 2.5 B 250 C 2,500 D 25,000
Vlada [557]

Solution:

we have been asked to find that , how many times one number is to the other given numbers.

To do this we will divide the larger number by the smaller number and the resulting number will be the answer of the question.

Here the larger number is 8.5\times10^8

The smaller number is 3.4\times 10^5

Now lets divide as follows

\frac{8.5\times10^8}{3.4\times 10^5} =\frac{8.5}{3.4}\times 10^{8-5}\\ \\\frac{8.5\times10^8}{3.4\times 10^5} =2.5\times10^3=2500

Hence the correct option is C.

Hi friends,
Fiesta28 [93]

d = b - 3 / 10

Step-by-step explanation:

b = 10d + 3

  • Place +3 in the other side of the equal sign
  • + 3 becomes - 3
  • b - 3 = 10
  • Divide both sides by 10 to make d the subject
  • b - 3 / 10 = 10d / 10
  • d = b - 3 / 10
