4x - 3 = 6x + 9 looking for variable

otez555 [7]

$\huge{\red{\boxed{\sf{x = - 6}}}}$

Step By Step Explanation:

Step 1:

→ $4x - 3 = 6x + 9$

Step 2:

→ $4x - 6x = 9 + 3$

Step 3:

→ $- 2x = 12$

Step 4:

→ $x = \frac{12}{ - 2}$

Step 5:

→ $\green{x = - 6}$

verification:

Step 1:

⇝ $4( - 6) - 3 = 6( - 6) + 9$

Step 2:

⇝ $- 24 - 3 = - 36 + 9$

Step 3:

⇝ $- 27 = −27$

Which numbers between 10 and 99 have digits that differ by 4 and add to 6

madreJ [45]

Answer:

Step-by-step explanation:

Correct option is A)

Let a 3-digit number ABC

Case (1)

If A=7, then B and C can be any digit but not 7

so, total 9 digits (0,1,2,3,4,5,6,8,9) can replace B and C

Then total such combinations =1(9)(9)=81

Case (2)

If B=7 then A can be any digit but not 0 and 7, because if A=0 it will be a 2-digit number.

And C can be any digit but not 7

Then total combinations =(8)(1)(9)=72

Case (3)

If C=7 then A can be any digit but not 0 and 7, because if A=0 it will be a 2-digit number.

And B can be any digit but not 7

Then total combinations =(8)(9)(1)=72

So, total numbers between 99 and 1000 which have exactly one of their digits as 7 are =81+72+72=225

The three angles of a triangle are in the ratio 5:4:1. Find all the angles of the triangle.

solniwko [45]

Answer:

Step-by-step explanation:

let the first angle be 5x

second be 4x

and third be 1x

as we know that by adding all the sides of triangle we get 180°

therefore ,

5x+4x+1x=180°

10x=180°

hence ,

x=18°

first angle - 18*5 = 90°

second angle - 18*4=72°

third angle - 18°
