5x + 7 < -3 or 3x - 4 > 11
rodikova [14]

Answer:

x < -2; x > 5          

Step-by-step explanation:

5x + 7 < - 3                  3x - 4 > 11

     -7     -7                         +4   +4

    5x < - 10                        3x > 15

    / 5     /5                          /3     /3

      x < -2                             x > 5

A) Complete this prime factor tree:
Ierofanga [76]

Answer:

2 * 2 * 3 * 3

Step-by-step explanation:

We are to write the value of 36 as a product of of prime factor

Factorizing 36;

2| 36

2| 18

3| 9

3| 3

| 1

Multiplying out all the factors;

36 = 2 * 2 * 3 * 3

Hence the prime factors of 36 are 2 * 2 * 3 * 3

in CAT the measure of the largest angle is 10 less than 5 time the smallest angle. The measure of the middle angle is 6 more tha
Vsevolod [243]

Answer:

The measure of middles angle is 113.5° .

Step-by-step explanation:

Given as :

The measure of the largest angle is 10 less than 5 time the smallest angle.

The measure of the middle angle is 6 more than twice the measure of the largest angle

Let The largest angle = L

Let The middle angle = M

Let The smallest angle = S

As per statement

Largest angle = 5 times smallest angle - 10

i.e L = 5 × S - 10                .....1

Again

Middle angle = twice largest angle + 6

i.e M = 2 × L + 6                ......2

Since for any Triangle sum of three angles = 180°

i.e ∠L + ∠M + ∠S = 180°

Or, ( 5 × S - 10 ) + ( 2 × L + 6 ) + S = 180°

Or,  ( 5 × S - 10 ) + [ 2 × (5 × S - 10 ) + 6 ] + S = 180°      

Or, 5 S - 10 + (10 S - 20 + 6) + S = 180°      

Or, 5 S - 10 + 10 S - 20 + 6 + S = 180°    

Or, (5 + 10 + 1) S - 24 =  180°    

Or, 16 S =  180° + 24

Or, 16 S = 204

∴  S = \dfrac{204}{16}

i.e S = 12.75

So, The measure of smallest angle = S = 12.75°

And

L = 5 × 12.75 - 10  

i.e L = 53.75

So, The measure of Largest angle = L = 53.75°

And

M = 2 × L + 6                

Or, M = 2 × 53.75 + 6

i.e M = 107.5 + 6 = 113.5

So, The measure of middles angle = M = 113.5°

Hence,  The measure of middles angle is 113.5° . Answer
