Answer:

v = \frac{5.4mT}{6T - 37}

v = -1.701*10^8

Step-by-step explanation:

Given

T = \frac{37v}{6v-5.4m}

Solving (a): Make v the subject

T = \frac{37v}{6v-5.4m}

Cross Multiply:

(6v-5.4m)T = 37v

Open bracket

6vT - 5.4mT = 37v

Collect Like terms

6vT - 37v= 5.4mT

Factorize:

(6T - 37)v= 5.4mT

Make v the subject

v = \frac{5.4mT}{6T - 37}

Solving (b):

T = 4.5

m = 7 * 10^7

So, the expression becomes:

v = \frac{5.4mT}{6T - 37}

v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}

v = \frac{170.1*10^7}{27 - 37}

v = \frac{170.1*10^7}{-10}

v = -17.01*10^7

v = -1.701*10*10^7

v = -1.701*10^8

Devisibility rules for 3, 6, and 9
fenix001 [56]

Answer:

<u>★</u><u> </u><u>Divisibility</u><u> </u><u>rule</u><u> </u><u>for</u><u> </u><u>3</u><u> </u><u>-</u>

If the sum of all the digits divisible by 3 then the number is divisible by 3.

Here, we take an example for better understanding -

<u>Example</u><u> </u><u>1</u><u> </u><u>-</u> 3525

Add up the digits - 3 + 5 + 2 + 5

→ 15

As, 15 is divisible by 3. So, 3525 is a factor of 3.

★<u> </u><u>Divisibility</u><u> rule</u><u> </u><u>for</u><u> </u><u>6</u><u> </u><u>-</u>

A number is to be divisible by 6 , if the number is also divisible by 2 and 3.

<u>Exampl</u><u>e</u><u> </u><u>2</u><u> </u><u>-</u> 132

Add up the digits = 1 + 3 + 2 = 6

As, 6 is divisible by 2 and it's also divisible by 3. Then, 132 is a factor of 6.

★ <u>Divisibility</u><u> rule</u><u> for</u><u> </u><u>9</u><u> </u><u>-</u>

If the sum of all the digits is divisible by 9 then the number is divisible by 9. Just like we'd in 3.

<u>Example</u><u> </u><u>3</u><u> </u><u>-</u> 1052

Add up the digits - 10 + 5 + 2 = 17

As, 17 is not divisible by 9. So, 1052 is also not divisible by 9.

Solve the equation to find the value of m and n.<br> 2m + 3n = -5<br> 5m + 3n = 1
Leokris [45]

Answer:

m = 2, n = - 3

Step-by-step explanation:

Given the 2 equations

2m + 3n = - 5 → (1)

5m + 3n = 1 → (2)

Subtract (2) from (1) term by term to eliminate n

2m - 5m = - 5 - 1

- 3m = - 6 ( divide both sides by - 3 )

m = 2

Substitute m = 2 into either of the 2 equations and solve for n

Substituting into (1)

2(2) + 3n = - 5

4 + 3n = - 5 ( subtract 4 from both sides )

3n = - 9 ( divide both sides by 3 )

n = - 3
